Hi CrUX users,

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

The 202104 (April 2021) dataset is now available and it covers 8,423,302 origins. Here's a look at origins' Core Web Vitals performance this month:
  • 49.4% of origins had good LCP
  • 89.8% of origins had good FID
  • 53.8% of origins had good CLS
  • 25.8% of origins had good LCP, FID, and CLS
We have two community resources to highlight:
Also take a look at Evolving the CLS metric by Googlers Annie Sullivan and Hongo Song. This post explains the upcoming implementation changes to the CLS metric. We'll notify you on these channels when the CLS changes take effect.
    If you have any questions about CrUX, feel free to reach out to us on any of these channels:
