Domain-level data: each row is a whole domain that links to opencongress.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 opencongress.org
opencongress.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.

How the authority score is calculated
The score is the average of two parts, each from 0 to 100:
- Rank part:
100 × (1 − log10(rank) / log10(N))^0.6, where rank is the domain's harmonic centrality position in the Common Crawl web graph (how close it is to every other domain through links) and N is the number of ranked domains (133,241,980). - Link part:
100 × log10(1 + referring domains) / 7, so 10 million referring domains = 100.
For this domain: rank part 64.2 (web graph rank 17,474 of 133,241,980), link part 45.1 (1,444 referring domains), average 54.7, rounded to 55.
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.
