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 77.0 (web graph rank 748 of 133,241,980), link part 55.6 (7,849 referring domains), average 66.3, rounded to 66.
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.

- sil.org has a domain authority score of 66 out of 100 (above average for a business website), based on 7,849 referring domains and a web graph rank of 748 among 133 million domains. The score is our own open-data metric (0-100) and is not Moz Domain Authority or Ahrefs Domain Rating.

- sil.org is linked to from 7,849 other domains in the Common Crawl web graph (release cc-main-2026-jul-aug-sep). This counts referring domains, not individual backlinks, and Common Crawl does not see the whole web, so commercial tools that crawl more will show larger numbers.

- Its web graph rank (harmonic centrality) is 748 out of 133,241,980 ranked domains, which puts it in the top 0.01%. Its PageRank position is 1,652. Majestic Million ranks it #3,408.
- Is the sil.org authority score the same as Moz DA or Ahrefs DR?
