Hi CrUX users,


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


The 202301 (January 2023) dataset is now available and it covers 18.2M origins, an increase of 8.2% over last month. Here’s a look at origins' Core Web Vitals performance this month:

  • 56.2% of origins had good LCP

  • 95.2% of origins had good FID

  • 73.1% of origins had good CLS

  • 43.0% of origins had good LCP, FID, and CLS

We’re seeing an overall increase in pass rates for the Core Web Vitals, especially the loading metrics, and we’ve internally validated that it’s real, but we’re not sure what the main reason is. Good INP has increased by 4.3% as well, to 75.6% of origins! This is due to an improvement in the Chrome scheduler. The next frame is now scheduled with highest priority after discrete input events, which shortens the lag between input event and visual update.


This month we've launched a CrUX History API, which provides 25 weeks of historical data at both origin and URL level. We've written a post detailing how to use this new API, and a Colab showing you an example of how to plot this historical data in various graphs. We're excited to see what you all build with it!

Cheers,

Johannes
