Core Web Vitals report within Google Search Console updated

Google has updated the Core Web Vitals report within Google Search Console. The update is around a change in the number of URLs that Google reports on within that report. Google said “because more URLs are now being reported on due to a new origin group that contains data for URLs that previously fell below the data threshold.”

What changed. Google is now reporting on more URLs because of a change in a new origin group, this may result in a bunch of URLs that were previously not reported on, to now be shown in this report. This change happened on March 27, 2023.

What Google wrote. Here is what Google posted in the data anomalies:

Why we care. A lot of SEOs work on core web vitals and this report update may impact some of the numbers and scores going forward. So you may find new opportunities to work on new URLs and improve the overall user experience of your pages.

Core web vitals are not a major Google search ranking factor, so generally small improvements with core web vital metrics do not translate to better rankings. But it is something one can and probably should focus on because it helps improve the overall user experience of your site.
