MOBILE ADVERTISING GUIDELINES

The MMA’s Mobile Advertising Guidelines provide recommendations for the global ad units broadly used in
mobile advertising in the following mobile media channels: Mobile Web, messaging, applications and mobile
video and TV. The Guidelines recommend ad unit usage best practices, creative technical specifications, as
well as guidance on ad insertion and delivery necessary to implement mobile advertising initiatives. The
guidelines are intended to promote the development of advertising on mobile phones by:
• Reducing the effort required to produce creative material,
• Ensuring that advertisements display effectively on the majority of mobile phones
• Providing an engaging, non-intrusive consumer experience.
The MMA’s Mobile Advertising Overview is a supplemental document that provides an overview of the mobile
media channels that are available to advertisers today, as well as the benefits of, and considerations for,
optimizing campaign effectiveness and strengthening consumer satisfaction. The Mobile Advertising
Overview can be found on the MMA Website at http://www.mmaglobal.com/mobileadoverview.pdf
The MMA guidelines are the result of ongoing collaboration across
the MMA Mobile Advertising Committee with representation from
companies in Asia Pacific (APAC), Europe, Middle East and Africa
(EMEA), Latin America (LATAM) and North America (NA).
Committee members are representative of all parties in the mobile
marketing ecosystem, including handset manufacturers, operators,
content providers, agencies, brands and technology enablers.
The target audience for these guidelines is all companies and
individuals involved in the commissioning, creation, distribution and
hosting of mobile advertising. The MMA Mobile Advertising
Guidelines present a baseline through which widespread adoption
will accelerate market development and ensure consumer
satisfaction.
Universal Mobile Ads
The MMA’s Mobile Advertising Guidelines are increasingly accepted across the industry worldwide. In order
to make preferred MMA ad units easier to define, adopt and reference, a subset of advertising units have
been defined as “universal” mobile ad units. These “universal” mobile ad units already enjoy broad support
across the industry.
The model for this package of ad unit identification is the Interactive Advertising Bureau’s Universal Ad
Package (UAP). The MMA hopes to adopt a similar structure in the future.
Publishers who are compliant with the MMA Mobile Advertising Guidelines will provide advertisers with at
least one of the ad units designated “universal” in this document, and will attest that those ad units have the
ability to reach the majority of that publisher’s audience. Publishers are also free to offer more ad units
beyond universal units.
Advertisers can be sure that by producing creative material according to these universal ad units, they will be
able to advertise through publishers who are compliant with the MMA Mobile Advertising Guidelines.
Advertisers are not obliged to provide all ad units in every case. Also, advertisers are free to use ad units
beyond those defined as universal.
The MMA is also working on an initiative with the Interactive Advertising Bureau (IAB) to drive accuracy in the
Measurement of mobile ad units.

2.0 Mobile Web
This section provides recommendations for the most prevalent advertising units on the Mobile Web; graphical
banner advertising and text links.
The Mobile Web features text and graphics optimized to match the specific screen resolutions and browser
capabilities of each user’s mobile phone. Therefore, a smartphone with a high resolution screen can be
served large, visually rich ads and a mobile phone with fewer resources can be served light-weight ads
designed for small screens with limited resolution.
In order to accommodate the wide range of mobile phone capabilities, it is recommended that advertisers
produce and provide ad creative in a few pre-defined dimensions, discussed in this section. The appropriate
ad unit is selected from this set of pre-defined forms based on a particular mobile phone model’s capabilities
so that it best fits the mobile phone’s display. This approach helps ensure a good user experience and
increases process and campaign effectiveness.
2.1 Mobile Web Advertising Unit Definitions
The recommended ad units for Mobile Web are as follows:
• Mobile Web Banner Ad is a universal color graphics ad unit displayed on a Mobile Web site. The
universal Mobile Web Banner Ad is defined as a still image intended for use in mass-market
campaigns where the goal is a good user experience across all mobile phone models, network
technologies and data bandwidths. In some cases, particularly in Europe, animated Mobile Web
Banner Ads may be available for supplemental use in campaigns to convey a rich media experience.
All Mobile Web Banner Ads must be clickable by the end user and may be placed in any location on a
Mobile Web site. Supplementary, a Mobile Web Banner Ad can be followed by a Text Tagline Ad to
emphasize the clickable character of the ad unit.
• WAP 1.0 Banner Ad is a supplemental black-and-white, still graphics ad unit for use in campaigns that
target older mobile phones. A WAP 1.0 Banner Ad can be followed by a supplemental Text Tagline Ad
to emphasize the clickable character of the ad unit.
• Text Tagline Ad is a supplemental ad unit displaying only text. Text links may be used in older mobile
phones not capable of supporting graphical images and/ or by publishers that prefer to use text ads
instead of graphical ads on their mobile sites.
2.2 Mobile Web Banner Ad Specifications
The recommended specification for a Mobile Web ad unit consists of a series of specification components,
i.e. aspect ratios, media formats, dimensions and file sizes. When providing inventory specifications,
publishers should remember to also quantify those parameters they support. Agencies and advertisers
should remember to verify the specifications with each publisher on their media plan.

Future: Mobile Web Banner Ads
The MMA recognizes the need to
provide larger than 300 pixels banner
dimensions. However, new mobile
phones coming to market vary in their
Mobile Web display characteristics
and clustering does not allow
identifying the most appropriate
dimension at this point in time. MMA’s
mobile advertising committee has
started exploring the opportunities of
using Rich Media as an advertising
format and plans to come up with
guidelines likely to feature flexible
widths especially beyond 300 pixels. In
the meantime, MMA encourages
experimentation in this space and
invites companies to share best
practice with the MMA mobile
advertising committee.
Future: File Sizes
The MMA recognizes that as new
mobile phones are introduced into the
market, and networks continue to
expand capacity, that file size limits
should increase accordingly. The MMA
has agreed to increase future
maximum file sizes to the limits
indicated in Appendix 2.
Specification Components
2.2.1 Aspect Ratios The recommended universal aspect ratios for
Mobile Web Banner Ads are 6:1 and 4:1. Key considerations for
providing universal aspect ratios include:
• Keeping the aspect ratio constant simplifies resizing of images
and reduces effort.
• Both aspect ratios provide sufficient creative space to ensure an
effective advertising experience, yet small enough not to be
intrusive. Having two aspect ratios gives publishers flexibility in
terms of layout and positioning in different contexts
2.2.2 Dimensions The recommended universal Mobile Web Banner
Ad widths are 120, 168, 216 and 300 pixels. Establishing guidelines
for Mobile Ad unit dimensions has several benefits:
• Limiting the amount of distinct dimensions reduces the amount
of time and resources spent on creative production.
• Dimensions selected provide a good fit for the majority of mobile
phones.
• Dimensions selected for Mobile Web Banner Ads provide for an
exact pixel height for both ratios defined which simplifies scaling of the creative.
2.2.3 Media Formats The recommended formats for Mobile Web Banner Ads are:
• GIF, PNG or JPEG as universal formats for still images.
• GIF for animated images.
2.2.4 File Size The maximum graphic file size is dependent on the
banner chosen. Tables 1 and 2 provide the maximum file size
recommendations across the banner ad unit types.
Character Limits for Text Taglines Character limits (rather than file
size limits) are applicable for Text Taglines appended to Mobile Web
Banner Ads. Screen width has no effect on text tagline sizes, which
Tables 1 and 2 summarize.
WAP 1.0 Banner Ad Specifications Appendix 1 provides a regional
summarization of WAP 1.0 ad specifications. This ad unit is still in use
in some markets, however, its importance, overall, is decreasing.
2.3 Mobile Web Advertising Creative Design Principles
In addition to the MMA Mobile Advertising Guidelines, other established guidelines for Mobile Web content
delivery should apply to Mobile Web sites containing image banners, as well as to Mobile Web sites that
users reach via links in image banners (post-click), such as jump pages, campaign sites and self-contained,
permanent third-party Mobile Web sites.
More detailed design principles and style guides for Mobile Web sites can be found in the W3C Mobile Web
Best Practices at http://www.w3.org/TR/mobile-bp. The MMA Mobile Advertising Committees also
recommends that Mobile Web sites conform to W3C mobileOK Basic 1.0 Guidelines, which are available at
http://www.w3.org/TR/mobileOK-basic10-tests.
Irrespective of using supplemental text taglines, the MMA recommends that advertisements contain some
form of call-to-action clearly identifiable by the user (e.g., “find out more” icon button).
Text Taglines
Text taglines are a supplemental feature that can be added to Mobile Web Banner Ad.
Mobile Advertising Guidelines
Mobile Marketing Association Version 4.0 www.mmaglobal.com Page 6 of 25
© 2009 Mobile Marketing Association
Purpose:
• In cases where consumers are unfamiliar with Mobile Web Banner Ads and may not realize that
Mobile Web Banner Ads can be navigated to and clicked on, they may have a greater awareness that
text taglines can be navigated to and clicked on.
• A Mobile Web Banner Ad with a text tagline may generate higher click rates.
• Some older browsers cannot navigate graphical elements at all. In those cases, a text tagline is
required to make the Mobile Web Banner Ad clickable.
Limitations:
• Mobile Web Banner Ads with text taglines together use more real estate (space in the usable browser
window), typically at the expense of other Web elements, such as navigation and content.
Media owners and publishers need to make a case-by-case decision about what best suits their business
requirements.
2.4 Mobile Web Advertising Insertion and Delivery
The following recommendations are for Mobile Web advertising insertion and delivery, as appropriate to the
technology.
2.4.1 Ad Indicators
Some publishers and markets recommend or require the use of ad indicators (signifiers) when displaying an
ad unit. The publisher or local market guidelines define the exact format and placement of the ad indicator.
Indicators are used with both text and banner ads:
• A Text link ad indicator is defined as text used to indicate the text link is an ad. An example is the use
of “Ad:” preceding the ad text link.
• A Banner ad indicator is defined as a portion of the Mobile Web Banner Ad used to display the ad
indicator and indicate the Mobile Web Banner Ad is an ad unit rather than content. The indicator
typically is located on the side or the corner of the ad unit and may use text (e.g., “AD” in English
speaking markets or “Anzeige” or “-w-“ in Germany) or an icon.
The Mobile Web Banner ad unit specifications in Section 2.1 are inclusive of the ad indicator. When choosing
to use an ad indicator, the MMA recommends that the ad indicator be included with the creative ad.
2.4.2 Functionality
Automatic resizing of Mobile Web banners
Some publishers and ad-serving solutions provide a capability to re-size the ad creative dynamically to match
the mobile phone’s screen dimensions and capabilities.
In cases where the publisher or ad-serving solution requires only one banner image, the MMA recommends
using the X-Large Mobile Web Banner ad unit specifications as the default re-sizeable banner. It’s important
that the creative takes into account both the impact of image re-sizing (i.e. certain amount of degradation of
image quality) and that the automatic resizing may not work well with animated banners.
Animated banner images
When using animated Mobile Web Banner Ads, please note:
• Mobile phones that don’t support image animation tend to render only the first image frame. For this
reason, the MMA recommends that the first image frame should contain the entire advertising
message, instead of leaving important information for subsequent frames.
• To date, automatic resizing of animated images does not always deliver ideal results. Therefore, the
MMA does not recommend applying automatic resizing with animated image banners. The MMA is
studying this issue in order to find a workable recommendation.
Mobile Advertising Guidelines
Mobile Marketing Association Version 4.0 www.mmaglobal.com Page 7 of 25
© 2009 Mobile Marketing Association
• There are several possible animation formats, including animated GIF, SVG, Flash, Silverlight and
interlaced JPEG. Animated GIF currently is the most widely supported on mobile phones. The MMA is
studying options for improvements that will be incorporated into future guidelines.
3.0 Text Messaging (SMS)
Short Message Service (SMS) is a communications service that allows the exchange of short text messages,
limited to160 characters, between mobile phones. It is also referred to as “text messaging” or “texting.” SMS
messages can be sent and received between virtually all operator networks. Virtually every mobile phone in
the world supports SMS, creating a ubiquitous market for SMS-based advertising campaigns. SMS supports
messages sent from one user to another, as well as messages sent from a machine, such as a PC,
application or server, to a user.
3.1 SMS Advertising Unit Definitions
The recommended ad units for SMS are as follows:
• Initial SMS Ad (Appended) is a universal text ad unit of variable length (often between 20-60
characters) appended to the content (or body) portion of the message containing the primary, nonadvertising
content of the message. This ad unit uses the remaining space after the content portion of
the message, and can be made available for advertiser usage by the publisher. As a principle, focus
should remain on the content portion which should not be compromised by the ad unit.
• Complete SMS Ad (Full Message) is a universal text ad unit with up to 160 characters available for
advertiser usage. There is no primary, non-advertising content in the message and this ad unit is
typically delivered as a reply to an Initial SMS Ad or “Text (keyword) to (short code)” call-to-action.
These ads may be delivered as part of an ongoing opt-in mobile advertising campaign.
3.2 Initial SMS Ad Specifications
Specification Components
3.2.1 Format SMS is a text-only medium. It does not support any rich media; however some mobile
phones with click-to-call or click-to-web capability will display colored links and underlining of URLs and
phone numbers. The font size is entirely controlled by the mobile phone and is not under control of advertiser
or publisher. Therefore the message renders differently on different mobile phones.
3.2.2 Length The length of the ad is the subject to the available space after the content. Consult your
publisher for the maximum allowable length. Current practice is typically ads under 20-60 characters, with
ads up to 80 characters. Advertisers should be aware that shorter copy allows for increased publishing
inventory availability.
When using double-byte characters (otherwise known as 16-bit) to send an SMS, the limit is 70 characters.
16-bit characters are associated with sending a Unicode text message, which is required to convey some of
the special characters used in non-Latin alphabets, such as Chinese, Japanese or Korean.
3.2.3 Location The ad copy will be inserted only at the end of the content portion of the SMS. In cases
where the sender uses a personal SMS signature, the ad should be inserted after the signature.
3.3 Complete SMS Ad (Full Message) Specifications
Specification Components
3.3.1 Format See Short SMS Ad format
3.3.2 Length A length of up to 160 Latin characters
3.3.3 Location The Complete SMS Ad will be the entire SMS message.
3.4 SMS Advertising Insertion and Delivery
Mobile Advertising Guidelines
Mobile Marketing Association Version 4.0 www.mmaglobal.com Page 8 of 25
© 2009 Mobile Marketing Association
3.4.1. SMS Ad Indicators
The publisher or advertising insertion partner is responsible for including an ad indicator in Initial (Appended)
SMS Ads. There should be a clear separation between the text message content and the ad. A carriage
return or line break is recommended, however not all carriers support line breaks, so an ad indicator should
also precede the ad copy. Acceptable ad indicators are:
• “*” (single asterisk)
• “**” (double-asterisk)
• “AD:” (or similar local language abbreviation)
• “-“ (dash)
Note that a carriage return may count as two characters.
3.4.2 SMS Ad Functionality
Delivery
• Delivery of SMS Ad messages should be consistent with the MMA Global Code of Conduct. In the
U.S., SMS Ad messages should also follow the MMA Consumer Best Practice Guidelines:
http://www.mmaglobal.com/bestpractices.pdf
• SMS Ad messages should be delivered per the watershed hours requirements of your local market.
Response (return SMS)
• If a user requests additional information be delivered to them via SMS, advertisers should respond to
that request within 12 hours or the request (opt-in) for that particular message will be deemed expired.
• Responses to user requests may be delivered by an alternate common short code or phone number,
but the relationship to the original request should be clearly identifiable by the user. (For information
about short codes, see the MMA Common Short Code Primer, available at
http://www.mmaglobal.com/shortcodeprimer.pdf )
Click-to-call
• Phone numbers should be local or domestic to the country that the ads are targeting.
• Phone numbers should be functional. Ensure that the numbers are in service before the campaign
launches.
• Premium destination numbers that would result in a charge that exceeds standard rates to the end
user should not be used unless the terms are fully disclosed in the ad.
• Emergency numbers (e.g., 911 in the United States and Canada, or 112 in parts of Europe), or any
unrelated service numbers, are not allowed in SMS ad units.
Link to Mobile Web site
• Landing page should be viewable in Mobile Web browsers.
• Content of the linked Mobile Web site should be related to the advertisement.
• The landing page should be working properly.
• Please see Section 2.3 of this document for best practices on mobile web content.
3.5 Creative Design Principles
The primary design goal should be that the SMS Advertising unit is clearly identifiable as an advertisement
and is easily understood by the receiver of the message. The following design principles are suggestions.
3.5.1 General Design Principles for SMS Ads
• Use abbreviations and “text speak” (e.g., LOL) with caution and avoid grammatical errors or
misunderstandings.
• Use punctuation when required for clarity or emphasis.
Mobile Advertising Guidelines
Mobile Marketing Association Version 4.0 www.mmaglobal.com Page 9 of 25
© 2009 Mobile Marketing Association
• Note that a carriage return may count as two characters.
• Conduct testing to ensure that the publishing network recognizes, and mobile phones properly render,
any non-Latin or accented letters prior to use.
• Note that URLs contained in the text may allow click through to Mobile Web pages, depending on
handset capability, and may appear underlined or in color.
3.5.2 Design Principles for Initial SMS (Appended) Ads
• If a URL is included in an appended ad, the URL should be as short as possible. A URL under 20-
characters is recommended.
• To optimize the potential for frequency of delivery, the advertiser may develop several versions of ads
with varying lengths, maximizing the ads’ availability for insertion based on the length of the content
portion of the message. For example, “Nike” or “Just do it - Nike.”
3.5.3 Design Principles for Complete SMS (Full Message) Ads
• The Complete SMS Ad unit can be used for any type of promotional message or call to action.
• The advertiser should be clearly identified in the ad copy.
• Creative may contain a URL. Use of short URLs is recommended to use reduce character count and
maximize clarity and use of advertising space.
• The title or header of the message should reflect the consumer query or subscription that resulted in
delivery of the full ad message copy. For example, if the consumer replied “HOME” to get more info on
real estate, the resulting ad should have “HOME” in the first line. If the resulting ad is unfamiliar, the
recipient may dismiss it as “Spam”.
4.0 Multimedia Messaging (MMS)
Multimedia Messaging Service (MMS) is a rich media messaging service that allows mobile users to send
and receive messages that can include graphics, photos, audio, video and text. As such, it provides
marketers with increased ad effectiveness over SMS. Another benefit is that unlike the Mobile Web, this
media resides on the user’s mobile phone, so a data connection isn’t required to access the ad content once
the message has been received. It should be noted that unlike SMS, MMS is not yet universally supported by
all operator networks and all mobile phones; however the advertising opportunity using MMS is significant.
These guidelines seek to ensure a clear distinction of MMS Advertising units from content to avoid perception
of MMS Advertising as unsolicited communication and ensure maximum ad campaign effectiveness.
The MMS guidelines consist of a set of ad unit dimensions, file formats and maximum file sizes, as well as
additional considerations for advertisers and publishers.
4.1 MMS Advertising Unit Definitions
The recommended ad units for MMS are as follows:
• MMS Short Text Ad is a supplementary text ad unit appended to the content (or body) portion of an
MMS slide containing the primary, non-advertising content of the MMS slide. A MMS Short Text Ad
can contain links that are clickable by the end user. As a principle, focus should remain on the content
portion of the MMS slide which should not be compromised by the ad unit.
• MMS Long Text Ad is a supplementary text ad unit filling all of an MMS slide, whereby the text can
contain a link that is clickable by the end user.
• MMS Banner Ad is a supplementary color graphics ad unit displayed at the top or bottom of an MMS
slide. The supplementary MMS Banner Ad is defined as a still image intended for use in mass-market
campaigns where the goal is a good user experience across all mobile phone models, network
technologies and data bandwidths. However, in some cases, particularly in Europe, supplementary
animated MMS Banner Ads are available for use in campaigns where it is imperative to convey a rich
media experience. An MMS Banner Ad can be clickable by the end user, in which case a separate
Mobile Advertising Guidelines
Mobile Marketing Association Version 4.0 www.mmaglobal.com Page 10 of 25
© 2009 Mobile Marketing Association
text link can be considered. The MMS Banner Ad unit specification is similar to the Mobile Web Banner
Ad specification in terms of aspect ratio and dimension.
• MMS Rectangle Ad is a universal color graphics plus optional text ad unit filling all of an MMS slide,
whereby the text can contain a link. The universal MMS Rectangle Ad is defined as a still image
intended for use in mass-market campaigns where the goal is a good user experience across all
mobile phone models, network technologies and data bandwidths. However, in some cases,
particularly in Europe, supplemental animated MMS Rectangle Ads are available for use in campaigns
where it is imperative to convey a rich media experience. An MMS Rectangle Ad can be clickable by
the end user, in which case a separate text link below the graphics is recommended. An MMS
Rectangle Ad can be placed before the original content (pre-roll), within (mid-roll) or after (post-roll) of
the MMS, on a separate slide. Mixing an MMS Rectangle Ad with other content (except audio) on one
slide is not recommended.
• MMS Audio Ad is a supplementary audio clip that is played while an MMS Rectangle Ad or an MMS
Full Ad is displayed.
• MMS Video Ad is a supplementary video ad unit and usually gets delivered as part of a MMS Full Ad.
• MMS Full Ad is a supplementary ad unit which only contains advertising content. The MMS Full Ad is
a complete MMS composed of elements of MMS Short Text Ads, MMS Long Text Ads, MMS Banner
Ads, MMS Rectangle Ads, MMS Audio Ads and MMS Video Ads and distributed over one or multiple
slides. There is no primary, non-advertising content in the MMS Full Ad and this ad unit is typically
delivered in response to an ad request or based on some form of valid consent (opt-in) provided by the
recipient.
4.2 MMS Advertising Unit Specifications
Specification Components
The following ad unit specifications provide the framework for producing MMS ad creative material suitable
across a broad range of mobile phones with a compelling and engaging user experience.
4.2.1 Media Formats for MMS ad units are as follows:
• JPG or GIF as universal formats for still images.
• GIF for animated images.
• AMR-NB (on GSM networks) and QCELP (on CDMA networks) are prevailing audio formats.
• AAC+, AAC, MP3, WAV (PCM encoded) become increasingly available on mobile phones.
• 3GP and 3G2 the are prevailing video formats. Recommended audio quality: @ 16bit 44 KHz Stereo;
Recommended video quality: QVGA @250kbps, 20-30 frames per second.
4.2.2 Aspect Ratio
Mobile phones vary substantially in their screen display designs: landscape, square or portrait. Unlike in the
Mobile Web, MMS creators have no visibility of the individual target mobile phone and its screen
characteristics at the time of MMS composing.1
As a consequence, and to keep the need for vertical scrolling of ad messages to a minimum, the MMA
recommends using any landscape aspect ratio for MMS Rectangle Ad images. This typically includes 16:9
and 4:3 ratios. Also, a 1:1 (square) ratio can produce acceptable results. Such aspect ratios usually allow for
ad text to be visible together with the ad image on screens. Portrait aspect ratios are not recommended.
For the MMS Banner Ad, aspect ratios apply as defined for the Mobile Web Banner Ad units in Section 2.2
(6:1 and 4:1).
1 Mobile operators and MMS service providers (e.g. VASP) may be able to provide information of individual users’ mobile phone
display and media capabilities, which can be used to build richer and even more engaging MMS ad campaigns.
Mobile Advertising Guidelines
Mobile Marketing Association Version 4.0 www.mmaglobal.com Page 11 of 25
© 2009 Mobile Marketing Association
For MMS Video Ads, the recommended aspect ratios are the following:
• 16:9 (HD)
• 4:3 (QVGA)
• 11:9 (QCIF)
4.2.3 Dimensions
For all graphical MMS Ad elements, regardless of their aspect ratio, widths are recommended as defined for
the Mobile Web Banner Ad units in Section 2.2, i.e.
• X-Large MMS Image (width 300 pixels)
• Large MMS Image (width 216 pixels)
• Medium MMS Image (width 168 pixels)
• Small MMS Image (width 120 pixels)
• Respective heights being according to the aspect ratio selected.
The Large MMS Image width (216 pixels) is the universal dimension recommended for use in MMS Ad
campaigns where only one dimension is used. This width has proven to produce satisfactory user experience
across today’s mobile phones in mature mobile markets.
For all MMS Video Ad elements, the following are the most common examples of frequently used
dimensions:
• Large MMS Video (320 x 240 pixels)
• Medium MMS Video (176 x 144 pixels)
• Small MMS Video (128 x 96 pixels)
4.2.4 File Size
The maximum MMS message file size available for advertisements depends on the following factors:
• Mobile phones are currently capable of receiving MMS messages between a maximum of 100 KB to
600 KB sizes2.
• Mobile network configurations apply irrespective of the mobile phone capability. Currently most
networks support a maximum of 300 KB. However, some networks already increase this limit to 600
KB.
In order to reach a broad audience, the MMA recommends that the complete MMS file size does not exceed
300 KB. Maximum MMS file size and maximum ad file sizes are inclusive of all applicable elements (e.g.,
graphics, text and audio3).
• For ads inserted to other content, the MMS ad file size should not exceed 100 KB. This limit allows 200
KB or more for the original content. This file size allows for good quality MMS Rectangle Ad images,
even for many animated images.
• For the MMS Full Ad unit, a maximum file size of 300 KB is recommended.
4.3 MMS Advertising Creative Design Principles
4.3.1 Sender identification
The sender of the MMS Full Ad message should be clearly identifiable by the message recipient. The “from”
and “subject” field as well as the first message slide should reflect the consumer request or opt-in context that
2 The number of mobile phones supporting less than 300 KB maximum MMS size is decreasing.
3 In case of using SMIL, about 1 KB of formatting information should be considered part of the MMS size.
Mobile Advertising Guidelines
Mobile Marketing Association Version 4.0 www.mmaglobal.com Page 12 of 25
© 2009 Mobile Marketing Association
resulted in delivery of the full ad. The message subject field alone is not sufficient for carrying this information
because it is not shown on many mobile phones.4
For example, if the consumer has opted in to receiving advertisements from brand XYZ, the full ad messages
delivered should have “XYZ” not only in the “from” and “subject” field but also in the first element (text or
graphic) of the first slide. Local market guidelines or regulation might be in place requesting sender
identification placement.
4.3.2 Ad Indicators
Advertisers should consult their publisher and local markets to determine requirements for ad indicators.
Indicators could be used with both text and graphical ads:
• Text ad indicators, where text is used to indicate the text is an ad. An example is the use of “Ad:”
preceding the ad text. See also Section 3.4.1 on SMS ad indicators for more guidance.
• Graphical ad indicators, where a part of the creative is used to display the ad indicator and thus make
it clear that the graphic is an ad rather than content. The indicator typically is located on the side or the
corner of the creative and may use text (e.g., “AD” in English speaking markets or “Anzeige” or “-w-“ in
Germany) or an icon to indicate that the image is an ad.
The ad indicator is part of the graphical and text ad elements as per the technical specifications in Section
4.2. The MMA recommends that when advertisers choose to use an ad indicator, it should be included with
the creative material. Conventions for ad indicators vary by market and publisher.
4.3.3. Illustrations
The following example seeks to illustrate a possible pre-roll design.
4.4 MMS Advertising Insertion and Delivery
4.4.1 Impact of Transcoding and Rendering of media on mobile phones
MMS Message delivery includes two steps, transcoding and rendering; both which potentially impact the
quality of the message, its formats, and the resolution of media elements.
4 Please reference the MMA Global Code of Conduct: http://www.mmaglobal.com/codeofconduct.pdf
Example 1: MMS Pre Roll
Key elements are:
← Announce the service
← Clearly distinguish publisher brand from
advertisement
← Inform customer that the content
message will display on the following
slide(s)
Mobile Advertising Guidelines
Mobile Marketing Association Version 4.0 www.mmaglobal.com Page 13 of 25
© 2009 Mobile Marketing Association
Many mobile operators support transcoding, also known as media adaptation. Transcoding, which
automatically adapts content during message delivery, is done according to the receiving mobile phone
capabilities (e.g. screen resolution, maximum message file size, supported media formats) to avoid negative
user experience. While transcoding ensures that advertisements (along with possible other content) are
consistently presented on all mobile phones, it can have a negative impact on the audio and visual elements
if applied extensively. The ad unit specifications as defined in chapter 4.1 seek to reduce the need for
transcoding, and retain the quality of the ad creatives.
Transcoding and rendering have advantages that are relevant for the purpose of MMS advertising:
• To provide a good experience for users on almost all MMS-capable mobile phones.
• To allow creative material to be provided in one version only.
However, some caution is recommended:
• Image creative should be chosen that properly resizes down to lower resolutions. For example, tiny
text and graphical details should be avoided.
• Extensive media adaptation (from very large graphics down to very small ones) may render some
creative material into poor quality for low-resolution mobile phone screens. This can happen to
graphics containing text, details, thin lines or color palettes with texture.
• Creative producers are recommended to contact MMS service providers and/or network operators for
more details. In case transcoding is not available on a network, only the standard audio formats (AMRNB
on GSM networks and QCELP on CDMA networks) are recommended in MMS advertising5 6.
The process of MMS delivery can influence the content of MMS, therefore; testing the impact of resizing on
quality and legibility of the creative material is recommended. The MMA further recommends that MMS ad
delivery be tested on real phones prior to any campaign execution.
4.4.2 Synchronized Multimedia Integration Language (SMIL)
For MMS messages, SMIL defines the order of images and text on a slide, the time a slide is displayed, and
other parameters. Media creators should consider the following SMIL parameters:
• Region – defines the order of text and graphics on MMS slides. It determines whether all slides of an
MMS will start with graphics followed by text or vice versa. Without this parameter it is up to the MMS
client to set the order of image and text on one slide, which may lead to an unfavorable display
representation.
• Height – determines the percentage of display space reserved for text and graphics respectively; this
enables forcing the display of text below a picture in the visible area of the mobile phone display.
• Duration (dur) – controls the duration of display for each individual slide of the MMS. This parameter
is of importance to synchronize the duration of slide display and length of audio play measured in
seconds. If not properly set, the slide show may progress to the next slide before the audio (or video)
has finished playing.
4.4.3 Other Considerations
International Roaming
Inserting ads into MMS messages sent to users who are roaming abroad can generate additional costs for
those users because they typically pay roaming fees for MMS data usage. The industry is still developing
best practices for this situation. Some MMS service providers/operators provide the ability to block ad
injection and sending ad MMS messages to roaming users, thus ensuring a good customer experience. If
possible, this option should be used.

V1_3-20080128-C.pdf
6 The MMA recommends to extend the capabilities of MMS audio composition tools to include the mandatory formats as defined in the
standards

Response timing (return MMS)
If a user requests advertising information to be delivered to him via MMS, this request should be respond to
within 12 hours or the request (opt-in) for that particular message will be deemed expired.
MMS Video Ads
Advertisers should consider the following when developing MMS Video Ads:
• Avoid using fast-moving videos
• Avoid rapid scene changes (many scene changes in a short period)
• Avoid using small letters for advertising messages
For further considerations, please refer to the Mobile Video and TV Advertising Creative Design Principles in
Section 5.2.
5.0 Mobile Video and TV
This section provides recommendations for the most prevalent advertising units used in Mobile Video and TV.
5.1 Mobile Video and TV Advertising Unit Definitions
The recommended ad units for Mobile Video and TV are described as follows:
Ad Breaks are video or still/animated image advertisements rendered before, during or after streamed or
downloaded Mobile Video and TV content.
Linear Ad Breaks take over the full mobile display screen and replace the streamed or downloaded video
content for a given period of time. Ad unit formats include:
• Billboard Ad –a static image or brand logo typically displayed full screen before or after the video
content
• Bumper Ad – a short video advertisement or sponsorship indent typically shown before or after the
video content
• Pre-Roll Ad – a video advertisement shown prior to the video content
• Mid-Roll Ad – a video advertisement appearing as a break during the video content
• Post-Roll Ad – a video advertisement shown after the video content has ended
• Book Ending Ad – a Pre-roll video advertisement with a corresponding bumper ad from the same ad
campaign appearing at the end of the video content
Non-Linear Ad Breaks share the mobile display with the streamed or downloaded video content for a given
period of time. Ad unit formats include:
• Overlay Ads are still/animated image advertisements that appear over top video content during
playback. These ads can be semi-transparent or opaque and can be shown for the full or partial
duration of the video content (appear/disappear effect). Variations include horizontal or vertical
promotion banners, sponsorship skins (picture frames) and ad bugs.
• Companion Ads are still/animated image advertisements that appear adjacent to video content during
playback. Variations include drop-down horizontal banners or L-shaped banners that surround a
resized video (shrink and surround).
Interactive Mobile Video and TV Ads are advertisements that allow for user interaction including clicking,
browsing, zooming. Guidelines for these types of Mobile TV and Video advertisements are still being
researched by the MMA but may include click-to-web, click-to-call, click-to-SMS, click-to-video, click-todownload,
click-to-locate, click-to-ad etc .

© 2009 Mobile Marketing Association
5.2 Mobile Video and TV Ad Break Specifications
5.2.1 Aspect Ratios
Although most handset display screens have a portrait format, Mobile Video and TV content is typically
created and rendered in a landscape format. Recommended landscape aspect ratios for Mobile Video and
TV content are 4:3, 16:9 and 11:9.
5.2.2 Ad Placement and Length
Shorter ad break durations of 15 seconds (also 10 – 20 seconds) are recommended for short form video
content of 3 to 5 minutes in length. Longer form video content over 5 minutes may support ad breaks of 30
seconds or more but should be considered in consultation with the content publisher to ensure the best
consumer viewing experience.
Table 3: Mobile TV and Video Ad Breaks
Design Model Advertisement Placement Recommended Length
Bumper/Billboard Before or after content 5 seconds or less.
Pre-Roll only Before content Typically 15 seconds.
30 seconds or less
Mid-Roll only During content Typically 15 seconds.
30 seconds or less
Post-Roll only After content Typically 15 seconds.
30 seconds or less
Book Ending Before and after content Typically 15 seconds.
30 seconds or less
5.2.3 Video/ TV Ad Lengths Exceptions
Video downloads: The total file size of a downloadable video is important, especially for consumers
downloading over 2G connections. Due to the download time, a downloadable video is typically 30 seconds
in length, and may go up to 2 minutes in length. For downloads, the MMA suggests shorter pre-rolls and / or
short bumper, or vice versa depending on the length of the content (For example a 10-second pre-roll and a
3-second post-roll, or a 3-second pre-roll and a 10-second post-roll).
Broadcast TV: Mobile TV is still nascent, so more research is necessary to ascertain consumer preferences
regarding advertising lengths within mobile TV. “Traditional” TV ad breaks can be long (several minutes) and
should be reviewed with the publisher to ensure good consumer experience.
5.2.4 Media Formats
The recommended formats and resolutions for Mobile Video and TV ad units are:
• Video Ad Specifications (e.g. Pre-Roll Video Ad):
• File formats: WMV, AVI, MOV, MPEG2, .3GP
• Resolution/Aspect Ratio: QVGA, CIF, QCIF
• Recommended audio quality: 16bit 44Khz stereo
• Recommended video quality: 250kbps, 20-30 frames per second
Image Ad Specifications (e.g. Billboard Ad):
• File formats: .JPG, .PNG

Future: Location Based Advertising
The MMA recognizes the need to
provide guidelines for location based
advertising. However, models for using
location currently vary, and do not
allow identifying the most appropriate
guidelines at this point in time. MMA’s
mobile advertising committee has
started exploring the opportunities of
using location in advertising and plans
to come up with guidelines for location
based advertising. In the meantime,
MMA encourages experimentation in
this space and invites companies to
share best practice with the MMA
mobile advertising committee.
Mobile Video and TV Advertising Creative Design Principles
Advertisers should consider the following when developing mobile video/TV campaigns:
• Avoid using fast-moving videos
• Avoid rapid scene changes (many scene changes in a short period)
• Avoid using small letters for advertising messages
• Avoid dark shots
• Shoot made-for-mobile versions of commercials
Existing video advertising creative assets that have been shot for TV or online may not be optimal for mobile
and could need re-editing. For instance, text may be difficult to read, and fast-moving action that is too far into
the distance may not be visible or look good on the mobile screen.
6.0 Mobile Applications
This section addresses advertising guidelines for applications that
host ads inside the application design and logic. Specifications
presented here are applicable to a wide range of application types
comprising managed platforms, virtual machines, native applications
and widgets. There are applications that may not be able to make
use of these guidelines (e.g. ad units within idle screen applications).
These types of applications will be addressed in future releases of
these guidelines. For a more comprehensive overview of the mobile
applications landscape, please consult chapter 4.0 of MMA’s Mobile
Advertising Overview document
(http://www.mmaglobal.com/mobileadoverview.pdf).
6.1 Mobile Application Advertising Unit Definitions
The recommended ad units for Mobile Applications are as follows:
• In-App Display Advertising Units
Mobile Application Banner Ad – is a universal color graphics ad unit displayed on a Mobile
Application. The universal Mobile Application Banner Ad is defined as a still image(s), text or
combination of these, intended for use in mass-market campaigns where the goal is a good
user experience across all mobile phone models, network technologies and data bandwidths.
In some cases, animated Mobile Application Banner Ads may be available for supplemental
use in campaigns to convey a rich media experience. A Mobile Application Banner Ad can be
clickable by the end user and may be placed anywhere in a Mobile Application (e.g., on the
application main menu page or subpages).
Mobile Application Interstitial Ad - is a full-screen advertisement, which may be placed as a
“bumper” screen for the launch and exit of the application, or as a splash or jump page within
the application. It may be used as the landing page from an earlier ad banner or may be a
stand-alone Interstitial. This Interstitial may also be active or static.
• Integrated Ad – is an advertisement that is integrated with the application or game experience (also
known as product placement) and is formatted to be compatible with the main content type used in the
application context. It can be resized, reshaped and freely positioned as part of the core application
content. Respective guidelines are under study and expected to be added in future releases of this
document.
• Branded Mobile Application - many downloadable application advertising campaigns will continue to
be custom designed to support the needs and expectations of the target audience. Respective
guidelines are under study and expected to be added in future releases of this document.
Mobile Advertising Guidelines
Mobile Marketing Association Version 4.0 www.mmaglobal.com Page 17 of 25
© 2009 Mobile Marketing Association
• Sponsored Mobile Application – publisher’s downloadable application which features a sponsoring
arrangement at various places across the application. Respective guidelines are under study and
expected to be added in future releases of this document.
6.2 Mobile Application Advertising Unit Specifications
Specification Components
The following ad unit specifications provide the framework for producing In-App Display Ad creative material
suitable across a broad range of mobile phones with a compelling and engaging user experience.
6.2.1 Media Formats The recommended formats for In-App Display Ads are:
• JPG, PNG or GIF as universal formats for still images.
• GIF for animated images.
6.2.2 Aspect Ratios The recommended aspect ratios for In-App Display Ads include:
• Mobile Application Banner Ads: 6:1 and 4:1 as per the respective Mobile Web Banner Ad unit.
• Mobile Application Interstitial Ad: Any landscape aspect ratio as per respective MMS Rectangle Ad
unit. This typically includes 16:9 and 4:3 ratios and also a 1:1 (square) ratio.
6.2.3 Dimensions For all graphical In-App Ad elements, regardless of their aspect ratio, widths are
recommended as defined for the Mobile Web Banner Ad units in Section 2.2 (except for the Text Tagline unit
which does not apply in Mobile Applications), i.e.
• X-Large Mobile Application Image (width 300 pixels)
• Large Mobile Application Image (width 216 pixels)
• Medium Mobile Application Image (width 168 pixels)
• Small Mobile Application Image (width 120 pixels)
Respective heights are according to the aspect ratio selected.
6.2.4 File Size File size considerations are currently ongoing for mobile applications. For the time being,
following respective guidance from Mobile Web Banner and MMS Rectangle Ads is recommended (see
Sections 2.2.4 and 4.2.4).
6.2.5 Display Length
Mobile Application Banner Ad units are displayed with application content
• Banner Ads may be replaced periodically with a new ad. Refresh intervals may vary by publisher and
application.
Mobile Application Interstitial ads should be displayed in full, during which click-through actions are enabled.
• At any time the Interstitial ad is displayed in full, the user should be able to click to continue past the ad
into the content.
• A preliminary recommendation for Interstitial ad display time is that the units disappear after a
maximum of 5 seconds.
6.3 Mobile Application Advertising Creative Design Principles
6.3.1 Banner Ad Unit Creative Design Principles
Mobile Application Banner Ad units are presented alongside the host application. Banners may be presented
anywhere on the screen at the publisher or developer’s discretion.
Applications may contain a dividing area between the banner and application content, but this is applicationspecific
and not considered a part of the ad unit specification. Banner ads are opaque (zero image
transparency), such that the ad image does not blend with the application content.
Mobile Advertising Guidelines
Mobile Marketing Association Version 4.0 www.mmaglobal.com Page 18 of 25
© 2009 Mobile Marketing Association
Mobile Application Interstitial Ad units are intended for display on a complete screen or with minimal
components of the application (e.g., title bar or soft-button labels). Generally, Mobile Application Interstitial
ads should use as much of the screen area as possible. However, landscape or square aspect ratios seem to
allow the most flexibility for both Mobile Web and Mobile Application platforms, are convenient for advertisers,
and leave room for the title bar and/or soft-button labels.
6.3.2 In-App Display Ad Unit Actions
In-App Display Advertising Units can either be:
• Non-active/non-highlighted/static means that the ad unit is visible on screen, but it is not clickable.
• Active/highlighted/non-static means that the ad unit is in the “select” state. Users can click on it for
more information.
Action initiation:
Clicking on ad units provide opportunities for the user to receive additional information from the advertiser.
Both ad banners and Interstitial ad images may be active and link either to places inside the application or to
outside the application. This functionality must be consistent with a mobile phone’s capabilities (e.g.,
interactivity such as click-to-call, WAP push) and will be limited by both type of mobile phone and mobile
phone connectivity. Examples include:
• Click-to-Mobile Web: click launches the web browser.
• Click-to-call: click initiates an outgoing call to the content provider or advertiser.
• Click-to-video: click initiates an advertiser’s video commercial for a product or service.
• Click-to-SMS: click initiates an SMS for a user to send a keyword to a shortcode to request more
information.
• Click-to-locate: click initiates a map enabled by location-based services where a user may find, for
example, the closest car dealer or movie theatre.
• Click-to-buy: click initiates a jump page where a user may make a purchase using some form of
mobile payment (i.e. credit card, operator bill, etc).
• Click-to-storyboard: click transitions to a second interstitial ad (which itself may provide additional
actions).
For applications and games whose flow may be greatly disrupted by a click-through, click-through ads should
only display before the launch or exit of the application, or be queued until the end of the application
experience, or avoided altogether. If it is required to switch the user away from the application context, the
MMA recommends that, where possible, and in mobile phones that support click through, users are returned
to the place in the application that they left after interacting with the ad (e.g., World Series of Poker, with $1
million in chips).
If there is a risk that switching the user away from the application context will cause the application to
terminate, requiring the user to completely re-launch of the application, the application developer or publisher
is recommended to apply specific user warnings as follows:
• Notification: Clearly notifying users that they will be leaving the application environment to
experience the advertisement. And clearly communicating that, in most cases, users will need
to completely re-launch the application in the same way they started the application.
• Right to Cancellation: Giving users the option of interrupting the action to return to the
application.
For ads displayed during the use of an application, MMA recommends using banners or interstitials that avoid
switching the user away from the application context (e.g. expandable banners).

7.0 Technical Requirements for Mobile Advertisers
Advertiser/merchant site infrastructure
• Advertisers are responsible for the infrastructure costs for a site or associated click-through pages
including: keeping up with traffic demands, communications, hosting, hardware and software, as well
as the costs of implementation.
Ad unit serving
• Ad-serving infrastructure will serve the ad units defined in these guidelines to phones on-the-fly, based
on device-type detection and according to the best-fit principle, where the specification choice is based
on what a particular mobile phone’s screen can accommodate.
• Content that cannot be displayed by a mobile phone should not be delivered. For example, if a mobile
phone does not support GIF, then that format must not be served to that particular mobile phone.
Ad format testing
• The MMA recommends that tests be conducted prior to launching a campaign.
Automatic resizing of ad formats (optional and where applicable)
• Ad-serving infrastructure may be capable of performing automatic resizing, where a standard
dimension is dynamically adjusted to match the phone’s display while maintaining the aspect ratio of
the standard ad unit.
• Based on early experiences, automatic resizing works well for still images and provides value, such as
the ability to support large screens. The absence of MMA guidelines should not stop companies from
collecting experience in the field of automatic resizing by working along their own guidelines.
• Advertisers are advised to ensure that their creative is suitable for automatic resizing, especially in
cases where visual detail is essential.

10.0 MMA Guidelines Approval Process
The MMA implements a collaborative process for industry guidelines review and approval, prior to public
release. The process not only considers feedback from industry leaders and experts but also helps to
determine work streams for future releases. The summarized approval process is as follows:
• Committees generate a draft guidelines document developed and approved by MMA committee
member companies (“Committee”).
• Once the guidelines are approved by Committee, the guidelines are issued for public review. Public
review will last a minimum of four weeks.
• Feedback from the public comment period is circulated to Committee for review and incorporation as
appropriate. Note: In the event substantial revisions are suggested, the Committee must again
approve the guidelines prior to release.
• Once all approvals and feedback is gathered, incorporated and approved, the guidelines are released.
The guidelines are released every six months and are the result of collaboration across the MMA
Mobile Advertising Committee with representation from companies in Asia Pacific (APAC), Europe,
Middle East and Africa (EMEA), Latin America (LATAM) and North America (NA). If deemed
appropriate, the Committee may elect to release an interim revision of the guidelines.
