Hi CrUX users,


This is your monthly announcement that the latest dataset has been published to BigQuery.


The 202409 (September 2024) dataset is now available and it covers 18,936,684 origins, an increase of 2.9% over last month (reverting the usual dip we see over summer). Here's a look at origins' Core Web Vitals performance this month:


  • 65.4% of origins (↑ 0.9%) had good LCP

  • 78.2% of origins (~ 0.0%) had good CLS

  • 85.7% of origins (↑ 0.9%) had good INP

  • 51.0% of origins (↑ 1.8%) had good LCP, CLS and INP


This month includes the final rollout of the scrolling change exclusions mentioned last month, which likely helped with continual improvements in pass rates seen this month.


There was also another small change rolled out in the last month where pages with many events (over 150) may not have recorded INP correctly, but we do not expect many sites to be affected by this.


This is the first month without First Input Delay (FID) data in BigQuery since First Input Delay (FID) is now deprecated.


We had planned to remove ECT from BigQuery for this month, but are still working through its replacement so that has not changed yet.


And for those that missed it, we launched CrUX Vis this month—a new experimental CrUX tool to allow you to visualize CrUX History API data. See the announcement post for more details.


For the community shout outs this month, we're featuring some posts making use of CrUX data:


And finally, not quite community, but Rick from the Chrome Team wrote a post about how it was possible to view CrUX data in Chrome DevTools now thanks to some major improvements to the Performance Panel.

Cheers,

Barry
