Which practice would violate Google’s editorial and professional requirements?

  • Showing a ValueTrack tag in the text
  • Including a question mark in the headline
  • Directing people to a page other than the advertiser’s homepage
  • Including a border on the ad

The correct answer is:

  • Showing a ValueTrack tag in the text

Explanation:
Here are some examples of content that Google doesn’t allow:

  1. The promotion is incomprehensible or does not make sense
    • Examples: Gibberish ad text, overly generic or vague promotions, making ValueTrack tags visible in ad text, blurry image or video ad, blank or gibberish landing page content
  2. The promotion doesn’t accurately reflect where the user is being directed
    • Examples: Using the display URL “www.google.com” but leading to a landing page with the URL “www.youtube.com,” using the keyword insertion feature in the top-level or second-level domain of your display URL like “www.{keyword}.com”
  3. Promotions that do not name the product, service, or entity they are promoting, including animated ads that do not clearly display identifying information such as a product or company name, logo, or display URL on the final static frame (after the animation has ceased).
    • Examples: Not including identifying information, such as a product or company name, logo, or display URL in the promotion
