Set criteria for ad blocking in Verification

Update Verification settings to specify criteria to block ads from serving to:

  • A list of flagged domains
  • Content classifiers
  • Geographic targets

Flagged domains

You can choose an existing list or set up a new one. Campaign Manager will check this list whenever an impression is available. Campaign Manager will prevent your ads from serving to flagged domains and send brand-neutral ads instead. Note that you can only change the flagged domain lists for campaigns that have had impressions recorded. You can include second level subdomains (like but parent and subdomains cannot exist on the same list. If your list includes subdomains, and you wish to add their parent domain, the subdomains will be deleted. If your list contains a parent domain, and you wish to add its subdomains, you must edit or delete the parent first.

What are flagged domains?

Verification monitors the websites where your ads appear, or where they are about to appear. You can create flagged domain lists in Verification as a way to check whether your ads are serving to inappropriate or unwanted domains that are not right for your content. Verification sends you alerts when your ads appear on the wrong domains, or when they appear on a domain outside an approved list.

Using ad blocking, you can also enable campaigns to prevent your ads from serving to these flagged domains entirely. This effectively blocks your regular ads from all sites under those domains.

Block content classifiers

You can also select one or more content classifiers to specify content that should prevent Campaign Manager from serving an ad to a URL. 

  • Adult
  • Derogatory
  • Downloads & file sharing
  • Weapons
  • Gambling
  • Suggestive
  • Violence
  • Profanity
  • Drugs
  • Alcohol
  • Tobacco
  • Politics
  • Religion
  • Tragedy
  • Transportation accidents
  • Sensitive social issues

Note that you can use allowed domains in conjunction with flagged content to pinpoint where your ads can serve. For example, you might want your ads to appear on a particular site (say, that contains adult content, but to be blocked from serving on any other site with adult content. In that case, you would block the Adult classifier as shown above, but add to a list of allowed domains. 

Block geographic locations

You can select which geographic locations ads will be allowed to serve in. All others will be blocked.
