Source: Chrome UX Report (Google, CC BY 4.0), the monthly popularity lists of origins by real Chrome page loads. A rank is a bucket, not an exact position: "Top 10K" means among the 10,000 most visited origins. It measures reach in Chrome, not visits, so it is not Similarweb traffic. Rank lists by country: Traffic rank by country.

How the authority score is calculated

The score is the average of two parts, each from 0 to 100:

For this domain: rank part 65.7 (web graph rank 12,274 of 133,241,980), link part 50.6 (3,469 referring domains), average 58.1, rounded to 58.

It is consistent across all 120 million domains in the data, so it is good for ranking and filtering lists. It is not Moz Domain Authority or Ahrefs Domain Rating. Referring domains count other domains that link to this one, not individual backlinks; no list of linking pages is included.
