sd.gov is linked to from 12,225 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 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 71.0 (web graph rank 3,436 of 133,241,980), link part 58.4 (12,225 referring domains), average 64.7, rounded to 65.

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.
