Stronger than 99.99% of the 134,979,706 ranked domains (by harmonic centrality).

What 50 means

Top 0.1% of the web graph. Established brands and large publishers: only about 100,000 domains score this high.

Whether that is good depends on the sites you compete with. What counts as a good score · Compare with a competitor

What drives this score

OAR 50 adds up two positions in the cc-main-2026-aug-sep-oct link graph: harmonic centrality, worth up to 70 points, and PageRank, worth up to 30.

  • Harmonic centrality rank #9,72435.7 of 70 points
  • PageRank rank #17,23414.4 of 30 points

PageRank is the weaker signal here. It rises with the number and weight of links pointing at dkim.org, but it carries only 30% of the score, so harmonic centrality still moves OAR more.

Ranks are relative to each release, so a score can also move because the web around dkim.org changed. OAR describes position in the public link graph; it does not predict search rankings or traffic. How OAR is computed
