Best practices for DoubleClick Rich Media ad serving

  • Install the latest DoubleClick iframe solution
    See the DoubleClick iframe solution.
  • To avoid certain issues with iframes, we recommend that you implement JavaScript tags for rich media.
  • Our creatives are set to a high z-index default (999999-1000000). To avoid expansion layering issues, set any site-side drop down-menus (or float units) to a z-index higher than 1000001.
    This will ensure that drop-down menus expand properly over rich media. (For more information, see Site navigation drop-down menus are expanding under my rich media.)
  • Avoid using overflow:hidden to style ad container divs
    It's recommended that you change this to overflow:visible;. (For more information, see Expanding ad isn't expanding out of placement or over webpage.)

  • Avoid dynamically writing the ad tag to the publisher page
    DoubleClick doesn't support custom publisher implementations that move ads into place on a webpage. Examples of unsupported implementations include using DOM methods like appendChild and innerHTML to move ads around the page and dynamically writing an ad with custom JavaScript.

    In these scenarios place the ad tag directly on the page and confirm the issue. If the issue persists, contact DoubleClick support. If the issue is resolved, then it's a problem on the publisher's side.
