Chrome ad filtering
As of February 15, 2018, Chrome filters all ads on sites in Regions A and B if they've been in “Failing” review status for more than 30 days. Starting on July 9, 2019, Chrome will filter ads on sites in Region C if they've been in "Failing" review status for more than 30 days.
Here’s the timeline for Chrome ad filtering:
|Review status (learn more)||When Chrome ad filtering begins|
|Passing||(no ad filtering)|
|Failing||If your site is in “Failing” status, we’ll send an email to registered site owners and users at least 30 calendar days prior to the start of ad filtering, and you’ll have the opportunity to submit your site for an ad experience review.|
The Ad Experience Report is based on a sample of the URLs for a site. If violations are listed in the Report, then it’s likely that there are more violations on your site than those listed. To avoid Chrome filtering, fix the violations listed in the Ad Experience Report, along with any other violations, and then submit your site for another review. Learn more about ad experience reviews.
When your ad filtering status changes, it may take up to 8 hours before that change is fully reflected in ad delivery to your site. For example, when your ad filtering changes from “On” to “Off,” ads will begin to show to most users visiting your site via the Chrome browser almost immediately, but it may take up to 8 hours before they show to the remainder of users visiting your site via the Chrome browser.
