Domain-level data: each row is a whole domain that links to w3c.org at least once somewhere on its site, not a single backlink or page, and no anchor text or link type is included. Common Crawl samples the public web, so a link can be missing and commercial backlink tools will show more.

Traffic rank of w3c.org

w3c.org is not in any Chrome top list (global or country) in August 2026.

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 64.8 (web graph rank 15,210 of 133,241,980), link part 49.5 (2,931 referring domains), average 57.2, rounded to 57.

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.
