CrUX ad metrics added to the page experience SEO documentation

Google added the new Chrome User Experience Report (CrUX) ad metrics to the page experience search help documentation today.

Google added a single line under the page experience resources section that reads:

  • “CrUX ad metrics: These experimental CrUX metrics from Chrome can help you understand your site’s ad count, ad density, and ad weight metrics. They provide insight into real users’ ad experiences on your site, as seen and reported by Chrome.”

More about the CrUZ ad metrics. As we covered last week, Google said there are four new experimental advertising metrics to its Chrome User Experience Report (CrUX), its public dataset based on real-world Chrome user experiences.

The new measurements are:

  • Ad Weight – CPU: Processing resources consumed by ads, measured in milliseconds.
  • Ad Count: Average number of ads visible in the viewport.
  • Ad Density: Average percentage of the viewport occupied by ads.
  • Ad Weight – Network: Data consumed by advertising, measured in bytes.

Page experience in Google Search. In 2020, Google said page experience would be a search ranking factor. Over the years, Google downplayed the significance of page experience with rankings and made several updates to the documentation. In 2023, Google told us the Google page experience was never a ranking “system” but is still considered a ranking “signal,” Danny Sullivan, Google’s Search Liaison, said this morning.  These statements caused a lot of confusion, so Google clarified these in the updated documentation. Then in late 2024, Google removed the page experience report from Google Search Console.

John Mueller from Google told me on Bluesky:

We included them because they’re available as metrics to help evaluate the state of your site. Not everything is a direct search ranking factor! There are plenty of ways to improve the experience of a website, and sometimes having metrics makes it easier to discuss / work on it, “SEO” or not.

Why we care. Even if page experience is not a search ranking factor, it is something you should focus on. Making sure your pages are easy to use, fast to load, not distracting, not loaded with ads and just an overall good experience for your users is a good thing.

If it also leads to better rankings, that is a double win.
