Content Requirements

  • Only conventional graphical layout allowed: ads must occupy the entire space of the image size you've chosen. Ads cannot appear sideways or upside down. Ads cannot be segmented, contain multiple copies of itself within the ad, or otherwise appear to be more than one ad.
  • Ad images must be clear, recognizable, and relevant. Text appearing in the ad images must be legible. No low quality or blurry images.
  • Strobing, flashing backgrounds, or otherwise distracting ads are not allowed.
  • Ads cannot mimic news articles and features. They may also not contain screenshots of Google AdWords text ads or otherwise simulate an AdWords text ad in any way.
  • Image content and associated website content must be family safe. Any image ads that contain Non-Family Safe or Adult material in the ad or website will not be accepted.
  • „Trick to click“ ads not allowed: ads cannot pretend to be a system or site warning. Ads cannot mimic or resemble Windows, Mac, or Unix dialogue boxes, error message, etc. Ads can have mock animated icons or features such as button images as long as the purpose of these features can be achieved on the landing page.
  • Ads can have mock animated features or icons as long as the functionality works or the purpose of these features can be achieved on the landing page.
  • The sole purpose of the ad cannot be to play a contest or game or to win prizes. However, ads can promote sweepstakes and contests on their sites (specific to animated ads).
  • "Mousing effects" do not have to be user initiated. Ads can simulate mouse or computer actions like mimicking the movement of a mouse icon within the parameters of the ad, as long as the mousing effects stop after 5 seconds (specific to animated ads).
  • Must adhere to content restrictions (no politics, dating, religion, video games (casual & online), ringtones & downloadables, get-rich-quick, weight loss, cosmetic procedures & body modification, drugs & supplements, sexual & reproductive health, consumer loans, free gifts, quizzes & surveys, misleading claims, references to sex & sexuality etc.)

Info: Ad must conform to the AdX Content Policy. Full details available at AdX Policy Center.

Additional Flash Requirements

  • Tracking event constraints: AdWords does not allow the specific tracking of user interactions that don't involve clicks. Tracking parameters that are not allowed include:
  • View-through tracking
  • Key-modifier tracking
  • Mouse location tracking
  • Other behaviors: The AdWords system reviews the code of all Flash ads as they are uploaded. The following coded behaviors have restrictions on their use:
  • Extra calls: Your ad code cannot make external server calls for additional JavaScript or other functionality. All functionality must be localized to the code itself.
  • Tracking bypass: You cannot change the behavior of your ad to avoid or eliminate the AdWords redirect URL.
  • Destination changes: The ad should direct users to a web page with the appropriate destination URL. It should not open the destination URL within the ad iFrame itself.
  • Cursor behavior: Your ad may affect or change a user's mouse cursor (arrow) within the parameters of the ad, but the user should be able to stop this interaction if it is non-user initiated or it should auto-stop after 5 seconds.
  • Random numbers: Your ad may not include code that generates or uses random numbers.
  • Other disruptive behaviors: Ads may not be designed or coded to circumvent the basic and usual AdWords flow. This includes (but is not limited to) the ad being displayed normally to users, Google registering the impression, and a click directing the user to the destination URL indicated by the advertiser in their AdWords account.
