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

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 65.4 (web graph rank 13,137 of 133,241,980), link part 45.6 (1,563 referring domains), average 55.5, rounded to 56.
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.
