Block advertiser URLs

You can block specific ads from appearing on your pages. This is helpful when you don't want to display particular advertisements—for example, you may want to block ads leading to competitors' sites.

You can block ads that link (or, click-through) to specific URLs. This way, you can easily block all ads that are linked to your competitor at www.example.com. By entering a top-level domain such as www.example.com, you'll also block all ads that link to subdirectories below that domain.

Guidelines for blocking URLs

Action / component Guideline
When entering the advertising URLs you want to block
  • You can separate multiple URLs with commas or hard returns.
  • You can block a maximum of 25,000 URLs.
For URL paths
  • Entering example.com blocks ads to example.com and example.com/sub.
  • Entering example.com/sub does not block ads to example.com/products.
For subdomains
  • Entering example.com blocks ads to www.example.com and forums.example.com.
  • Entering www.example.com blocks ads to www.example.comforums.example.com, and example.com.
  • Entering forums.example.com blocks ads to forums.example.com but does not block ads to example.com, www.example.com, or admin.example.com.
For apps URLs are normalized for Google Play Store and iTunes URLs. This means you only need to add one variation of the URL to block the app from advertising on your property. For example, if itunes.apple.com/app/id12345 and itunes.apple.com/us/app/id12345 point to the same app, you only need to enter one of the URLs to block the app entirely.
For URLs that combine a top-level domain with a country code top-level domain (such as google.com.br) Explicitly include the country code top-level domain as part of the URL.
