Display Advertising HTML5 Guidelines

EBOSS can host advertising created in different formats, including HTML5.

When building your HTML5 zip bundle, please check your creative meets the following requirements:


  • Keep the overall file size under 150kb
  • Confirm your bundle is SSL compatible
  • If using Google Web Designer, choose "DoubleClick" as the environment

Size meta tags

  • Set creative dimensions in your HTML file with the size meta tag:
    <meta name="ad.size" content="width=270, height=225">
  • HTML5 creatives can only have fixed dimensions.
    For EBOSS advertising, our display advertising sizes are:
Lead Banner Website 728px 90px
Medium Rectangle 270px 225px

Click tags

  • Set click tags for each exit on your HTML5 creative
    • Make sure your creative uses the click tag variable as the click destination
    • The click tag should be easy for the ad server to read
    • We do not recommend hard-coded click-through URLs in the asset.

Sample Click Tag insertion

<meta name="
ad.size" content="width=270,height=225">
<script type="text/javascript">
var clickTag = "";

Your creative must use the click tag variable as the click-through URL:

<a href="">


Your HTML5 creative can be uploaded using the Creative Submission form, or by uploading it to your Dropbox account and sending us the link.
