Ad experience reviews

Desktop and mobile ad experiences

The list of annoying ad experiences is different for desktop and mobile environments. For example, flashing animated ads are considered to be more annoying on mobile devices than on desktop screens, and are part of the mobile ad standard, but not the desktop ad standard, each as defined by the Coalition for Better Ads.

Because of this, we review pages on both the desktop and mobile versions of your site, and you’ll see a review status for each environment in the Ad Experience Report. 

We review a sample of your pages

Ad reviews are not exhaustive—we do not look at every page of your site. Instead, we review a sample of pages and report on ad experiences we find. (If your review status is “Warning" or “Failing,” you can see the violations we did find in the “What we found” column of the Report.) When you submit your site for review, we again look at a new sample of pages, which means we may find ad experiences that we did not find on earlier reviews.

Currently, sites in Ad Standard region C are reviewed for information purposes only, and no Chrome ad filtering occurs on these sites.

About domains and subdomains

The Ad Experience Report shows issues that affect any page up to and including your root domain. Note that submitting your site for review implements a review of the entire site domain, not just the subdomains for which you are registered.

Review status

You'll see one of the following statuses at the top of the Report:

Not reviewed: We haven't yet reviewed the ad experiences on your site. As a best practice, we recommend preemptively fixing any ad experiences before we review your site. 

Passing: We reviewed your site and haven't detected a significant number of annoying ad experiences on your pages. 

Warning: We reviewed your site and detected a number of ad experiences that violate the Better Ads Standards. You should fix the issues as soon as possible and submit your site for another review. 

Failing: We reviewed your site and detected numerous ad experiences that violate the Better Ads Standards. You should fix the issues as soon as possible and submit your site for another review. If your site remains in this status, Chrome will filter ads.

Review pending: Your site has been submitted for a review. You’ll be unable to submit it for another review until we've completed this one. If your site was in "Failing" status, ad filtering may be paused during this time period.

Note: 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 review cycle

You should fix your site's issues and submit it for review if:

Note that restricted users can view the Report, but cannot submit the site for a review.

How often you can submit your site for review

You can request a review of your site twice without any delays. If your site remains in “Failing” status, you won’t be able to submit a 3rd or subsequent review for 30 days after you submit your previous review.  

Ad filtering status and review submissions

If your site is in “Failing” status, ad filtering is paused while your request is being processed. However, after your 2nd request, there is a 30 day period during which you can't submit another review; during this time period ad filtering will commence on the date specified in the Ad Experience Report if your site remains in "Failing" status.

Summary of review timing and ad filtering status

  • 1st review submission: ad filtering is paused while the request is being processed. If the result of the review is "Failing," a 2nd review can be submitted immediately.
  • 2nd review submission: ad filtering is paused while the request is being processed. If the result of the review is "Failing," a 3rd submission cannot be made for 30 days, and ad filtering commences upon the date specified in the Ad Experience Report.
  • 3rd and subsequent review submissions: cannot be made until 30 days have passed since the previous review submission, or until the site’s review status changes from “Failing” to “Warning” or “Passing.”
An example

The following example illustrates how ad filtering occurs if multiple site reviews do not address issues on a site whose review status is “Failing.”

Site example.com is notified that it's in "Failing" status, and that ad filtering will begin in 30 days. The following then occurs:

  1. An ad ops manager immediately fixes or removes some of the ad experiences and submits example.com for a review. This is the 1st review.
  2. 7 days later the review results come back, and the site remains in "Failing" status. 23 days now remain before ad filtering commences if the issues are not addressed.
  3. 3 days later the ad ops manager removes or fixes additional ad experiences, and submits the site for another review. This is the 2nd review. The site can now not be submitted for review for 30 days. If the site remains in "Failing" status, ad filtering begins in 20 days.
  4. 6 days later the review results come back, and the site remains in "Failing" status. The site cannot be submitted for another review for 24 days, but ad filtering will begin in 14 days. Unfortunately, this means that ad filtering will occur for 10 days before the site is eligible for another review submission.

Review processing and completion

While your review is being processed:

  • You’ll be unable to submit your site for another review until we've finished this one. 
  • The “review pending” label is added to the Ad Experience Report status bar.
  • The Ad Experience Report change log indicates that a review is pending.

When the review is complete:

  • The Ad Experience Report change log indicates that the review is complete.
  • The “review pending” label on the status bar is no longer displayed.
  • If we don’t find any significant issues, the status changes to “Passing.” If we found issues, your status may change to "Warning" or "Failing."
  • If issues have not been resolved, you can fix them and may be able to submit for another review immediately.
