The ad should be able to listen for the browser domcontentloadedeventend event before subsequent files beyond the initial max file size may be loaded Additionally, for ad units that allow video, another 1.1 MB of file size is allotted for auto-initiated 15-second videos, and 2.2 MB for auto-initiated 30-second videos in both display and mobile. User-initiated file size: 2MB Ads that allow additional file size for host initiated subload also allow for unlimited file load after user-initiated interaction. User initiation is the willful act of a user to engage with an ad. Users may interact by clicking the ad (or a portion of an ad). Max number of host-initiated file requests: 30 file requests during initial file load and host-initiated subload. Unlimited file requests allowed after user-interaction.

4 Files Supplied Direct (zip file) Guidelines Maintain an overall file size of less than or equal to 200KB, this includes all non-video, self-contained and external files Centaur Media will not be held responsible for H5 creative issues, nor will they troubleshoot H5 issues beyond trafficking a test page for testing purposes The advertiser/agency must ensure clicktag formatting is correct and Centaur Media is able to properly track clicks and impressions before the ad goes live The advertiser/agency is responsible for the optimization and packaging of the HTML files per the guidelines below. The advertiser/agency is responsible for cross-platform, cross-browser compatibility to include the implementation of proper fallback measures. Technical Considerations File Size ad size should be expected to be larger than what has been defined for traditional creative and should be discussed with other parties involved in delivering and placing the ad. The max file size should be negotiated with the publisher, File size measured after compressing the ad (all code and assets) to a.zip file The.zip file must include all referenced code such as Javascript libraries Some files such as JS libraries and Web fonts can be called form another location but must be considered as part of the overall file size Exceptions exist such as user-initiated videos which may be excluded from the overall file size Once the.zip is uncompressed, the ad must be viewable without a network connection The ad server should be able to predict ad drop-off rate from total file weight Optimization and Packaging tools for optimizations such as IDE are not yet available and being an open web technology means a large degree of development and creative freedom exist Code minifiers and compiler can assist in compressing code PNG crushers can reduce file size and scalable vector graphics (SVGs) is a lean method applicable to HD displays Use HTML text and scalable fonts whenever possible and consider font sub setting to increase legibility and reduce file size and download times. The number of individual files for an ad should be minimal and sprite sheets, code compilers and Base64 encoding of smaller images is recommended Maximize code efficiency so that it never uses the CPU to its capacity by using CSS styling and transitions for animations to divert processing power to the GPU Consider using gzip (.gz) compression which results in a smaller file size Ad Server Compatibly recommendations for maximizing compatibility with the ad server Ads must use the clicktag variable as the destination of the click event Click tags should be placed in the.html file without minification or obfuscation so the ad server can easily find the variable and substitute the correct value Hard-coded click-through URLs are required in the HTML for the ad server to track clicks When multiple.html files are included, the click tag variable must be present in the first.html file that loads Sample clicktag insertion: <html> <head> <meta name="ad.size" content="width=300,height=250"> <script type="text/javascript"> var clicktag = " </script> </head> [The rest of your creative code goes here.] </html> Your creative must use the click tag variable as the click-through URL: <a href="javascript:window.open(window.clicktag)"> <img src="images/dclk.png" border=0> </a> OR Place it in a container by making use of events: <div onclick="window.open(window.clicktag);"> <img src="images/dclk.png" border=0> </div> 4

5 Files Supplied Direct (zip file) - continued Ad Server Compatibly recommendations for maximizing compatibility with the ad server (continued) In instances of multiple clickthrough urls in the same ad, enumerate click tags as follows: clicktag0, clicktag1, clicktag2 Set the target attribute to _blank so the click destination opens in a new window or tab Ad dimensions must match placement dimensions to avoid distortion unless the ad is specifically designed to be responsive Ad dimensions should be defined within the <head> using the <meta> tag with the name ad.size For expansion or rich ads appearing in SDK based web applications, follow the IAB Rich Media Ad Interface Definition (MRAID) Fallback Since ad servers are not designed to detect compatibility in browsers the following fallback recommendations should be adhered to Fallbacks should be designed as part of the ad creative and should include the testing of ad features across browsers to ensure acceptable rendering Be aware of which features you use to ensure cross-browser compatibility Given that the ad server cannot control when to show a backup image it is not necessary, instead the ad code should detect what is failing and degrade gracefully <noscript> tag should be used to provide a path to an alternative image if a user has scripts disabled or client-side scripting is not supported (check to see if DFP uses this tag) Zip File Contents the.zip file submitted should follow the guidelines below There must be at least one.html file in the.zip which can load into an iframe and that includes at least one clicktag If multiple.html files exist the ad server should prompt the uploader for the appropriate.html file to use as the starting point Structure files as needed All code and assets should be relatively referred to by the.html file Minimize the number of files for performance reasons All code and assets should be contained in the.zip and the ad should be self-contained so that the ad is not dependent on a network connection Exceptions include files such as Javascript libraries, CSS source files or web fonts which, though external, are considered part of the overall size if loaded upon initial file load If there are multiple image files, ensure the images are named uniquely and are identifiable Add the alt attribute while using a similar naming convention to identify the creative to ensure accurate referencing and matching Example: <img src="creative[1].jpg" alt="img[1]" width="10" height="20"> <img src="creative[2].jpg" alt="img[2]" width="10" height="20"> <img src="creative[3].jpg" alt="img[3]" width="10" height="20"> Video and Animation guidelines for that make use of the video tag or animated content For in-banner video, video content is delivered by default to progressive download therefore the file weight should be kept small especially for mobile where a 2.5MB or smaller video is required (allow?) The video file is included as part of the ad s overall file size For animation the proper use of Javascript time controls like setinterval, settimeout and requestanimationframe are highly recommended to reduce CPU load jquery animation can delay animation playback therefore CSS animation is recommended To prevent code conflicts with the pub site the use of wrapping Javascript and CSS in closures or namespaces is recommended Because frames per second (FPS) for does not impact browser performance in the same way Flash does and cannot be defined by Javascript it is not required Tools Google Web Designer to build creatives in 5

Newer versions of Outlook (2007, 2010 and 2013) won't show the full animation, they will just show the first frame. We strongly suggest that you include the vital information (eg the call-to-action, offer, or headline) in the first frame of the GIF or supply a static JPG/GIF instead. You can also supply a sponsor message of up to 50 words.

HTML should be built using tables for compatibility - divs and referenced stylesheets are not supported on all clients. Graphic use should be kept to a minimum. Lots of graphics slow the user down in terms of reading the and clicking through. Image resolution should be 72dpi. We discourage the use of background images, animated gifs, videos and image mapping, since these aren't supported on all clients. If they are to be used, suitable fall-backs should also be in place. Only web safe fonts should be used & we suggest a minimum font size of 13 pixels. Our templates are 'mobile ready', so we encourage the use of media queries & other fluid coding techniques. Please ensure your html code has been fully tested before sending to us. If you require us to build the HTML, please supply a pdf or word doc, complete with approved copy, graphics & detailed instructions. We require a minimum of 48 hours for design, build and testing.
