• HTML5 Specifications
  • You may not use dynamic or expandable creatives as HTML5 creatives
  • Different browsers have different subsets of HTML5 features enabled. Your creative might fail on a browser if it attempts to use a feature that is not enabled in the browser. It is your responsibility to ensure that your creative “gracefully degrades” in case the browser it is viewed on doesn’t support the features it uses.
  • The IAB recommends adding the dimensions of your creative to your primary HTML document in a meta tag inside of thesection of your document. Here’s an example, in which you’d replace the width and height values with the actual dimensions of your creative:
    • < meta name="ad.size" content="width=300,height=250" />
  • The AlwaysOn Digital Hosted HTML5 system requires that you upload a static backup image. This image is used to display the ad if a user has JavaScript disabled.
  • Commonly used JavaScript and CSS libraries (such as jQuery) do not need to be included with the creative
  • Including image sprites instead of multiple images decreases the number of file requests made by your creative and increases its performance
  • File Sizes:
    • Initial Load: 300 KB max (200 KB recommended)

    • User-initiated Load: 2.2 MB (recommended)
  • File Packaging:
    • A single HTML file. All information for serving the creative (with the exception of commonly used JavaScript and CSS libraries) should be included in the HTML file. The maximum HTML file size is 200 KB.
    • A single root/main HTML file with supporting images
    • A single root/main HTML file with supporting images and additional supporting JS and CSS files
    • All files for displaying the creative (with the exception of commonly used JavaScript and CSS libraries) should be included in the ZIP file.
    • The primary HTML file should be located in the root of the ZIP file
    • ZIP files must contain no more than 100 files, including at least one HTML file for use as the initiating file for display. Keep the file count low to minimize browser performance impact.
    • You can include only HTML, JS, CSS, MP4, JPG, JPEG, GIF, PNG, and SVG files in a ZIP file
    • When packaging HTML5 creatives, include the asset files, not the folder containing them, in the ZIP file
  • Compressed Files Sizes:
    • Automatically-started Video: Less than 1.1 MB
    • Any Individual File: 2.2 MB max
    • Primary HTML FIle: 100 KB max
    • ZIP File Compressed: Less than 10 MB
    • ZIP File Uncompressed: Less than 12 MB
  • Click Tag Parameters:
    • You can customize the name of the URL parameter when uploading or editing the creative
    • Click tag names are case-sensitive. Be sure to use uniform capitalization throughout the creative and any supporting files. For example, clickTag and clickTAG are not interchangeable. The AlwaysOn Digital Platform defaults to clickTAG.
    • When the user clicks the ad, the creative must direct the user to the correct click tag page in a new window
    • If you want to also use that clickthrough URL in your HTML5 creative, you can configure the creative to use the backup clickthrough URL as the default clickthrough URL. To call the clickthrough page through the backup ad image correctly, you must supply a click- through parameter.
    • You can use multiple click-through URLs and define different landing pages for different actions. If you append a URL-escaped landing page to the click tag URL, the platform tracks the click and redirects the request to the given landing page.
      • var clickTAG = getParameterByName(“clickTAG”) + encodeURIComponent(“http://www.thetradedesk.com”);
        • TIP – Use JavaScript to read the parameter from the document location URL and use it to set up the landing page for your clicks. You can use either all single quotes (‘) or all double quotes (“) in your code, but you cannot mix them.

CONNECTED TV (CTV) ADS

• CTV creatives hosted by AlwaysOn Digital are automatically served in an SSL-compliant format
• To reach the most CTV inventory using third-party creatives, include a media file from each spec type
• CTV devices do not support the ability to click through to a landing page
• Certain requirements (such as bitrates) vary drastically by publisher
  • Typically, a minimum of 1200 kbps to 1500 kbps is required. A bitrate of 1.6 mbps to 3.2 mbps is preferred
• Most CTV inventory accepts only the VAST 2.0 standard for VAST bid responses
• File Format:
  • Only MP4 files are allowed for CTV ad placements
  • FLV and WebM files are not supported for CTV
• File Tags:
  • Third-party creatives must be VAST tags only
  • VPAID tags are not supported on CTV
  • While there is not a specific version of VAST that should be used with CTV creatives, keep in mind that VAST 3.0 and VAST 4.0 are typically less scalable. If you’re using a standard VAST tag that includes a VPAID component (for example, as part of an API framework), then this cannot cause any issues for your CTV creative. A VAST wrapper with VPAID functionality is not the same as a VPAID wrapper.
