What Google Chrome UX Report is

The Chrome User Experience Report is Google's public dataset of how real Chrome users experience the web. Alongside its performance metrics it publishes a monthly popularity ranking of the top million origins, grouped into magnitude tiers: the top 1,000, the top 5,000, the top 10,000, and so on down to the top million.

I read the tiers from the openly licensed crux-top-lists mirror, which republishes the ranking from Google's BigQuery dataset in a form that can be downloaded without a cloud account.

Why it can be relied on

  • The data comes from real Chrome users who opted into usage reporting, so it reflects actual browsing rather than a model.
  • It is Google's own measurement, published openly and on a fixed monthly schedule.
  • Because it is produced independently of Tranco, agreement between the two is a genuine cross-check, and disagreement is a flag worth looking into.

What is taken from it

A sanity check
When a site's Tranco rank and its Chrome tier tell different stories, I say so rather than picking the flattering one.

What it cannot tell me

  • The tiers are deliberately coarse. A site in the top 500,000 could be anywhere inside that band.
  • It measures Chrome users who share usage data, so browser mix matters at the margins.
  • It is monthly, so it lags a fast-moving site by a few weeks.
