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 63.7 (web graph rank 19,716 of 133,241,980), link part 45.4 (1,514 referring domains), average 54.6, 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.
