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 65.9 (web graph rank 11,800 of 133,241,980), link part 45.0 (1,406 referring domains), average 55.4, 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.

- holcim.com has a domain authority score of 55 out of 100 (moderate), based on 1,406 referring domains and a web graph rank of 11,800 among 133 million domains. The score is our own open-data metric (0-100) and is not Moz Domain Authority or Ahrefs Domain Rating.
- How many backlinks does holcim.com have?
- holcim.com is linked to from 1,406 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.
- How does holcim.com rank among all websites?

- Is the holcim.com authority score the same as Moz DA or Ahrefs DR?
