Verification

Limitations of Verification

Classification limitations

Site content classification is done automatically, using Google technology in a manner similar to Google Ads (learn more). As a result, we can’t manually verify every URL. There are several reasons why Verification may not be able to classify all traffic properly:

  • In some cases, pages might be classified incorrectly. For example, a word or phrase might indicate that a page refers to gambling, but a closer inspection might show that the reference was minor, irrelevant, or unrelated. To report a misclassified URL: click on the domain name in the content view >  then click Report Classification.

  • Not all pages have been classified. Your ads might have been served to pages for which we have no content data. We're working to increase coverage over time.

  • Some sites have a paywall or require you to sign in. In these cases, we can get the domain but not the exact URL.

  • If a referrer URL is blank, this may be due to a desktop or mobile application or the ad may be embedded within a web application.

Using the ins tag can provide better tracking for reporting data. More on the ins tag here.

Video limitations

In-stream video, VPAID, and in-stream video redirect creatives may have reduced availability for features that rely on VPAID, such as Active View and Campaign Manager Verification, based on how the publisher serves video ads. For these creative types to support measurement, you must have Active View enabled in in-stream video placement settings.

  • In-stream video creatives: Available if the publisher supports VPAID or uses the IMA SDK to serve video ads.

  • In-stream video redirect creatives: Available if the publisher supports VPAID or uses the IMA SDK to serve video ads. You also need to set the VPAID measurement adapter in your placement in-stream video settings to "On" and cannot use the “Let Campaign Manager decide” option. This prevents Campaign Manager from sending a blank tag if a publisher does not support VPAID..

  • VPAID creatives: Available if the publisher supports VPAID or uses the IMA SDK to serve video ads.

You can check with your publisher to see if these features will be available for their site.

Language limitations

Brand safety categories (in Display & Video 360) and content classifiers (in Campaign Manager) are available in most languages, but if you are unsure about a specific category in a given locale you may want to contact your support representative. 

Custom classifiers and entities work in the following languages:

  • English
  • German
  • Japanese
  • Spanish
  • Russian
