What 39 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 39 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 #59,51028.9 of 70 points
- PageRank rank #280,1629.9 of 30 points
PageRank is the weaker signal here. It rises with the number and weight of links pointing at bra.in, but it carries only 30% of the score, so harmonic centrality still moves OAR more.
Rank needed for a higher score
| OAR | Harmonic centrality rank (PageRank unchanged) | PageRank rank (harmonic centrality unchanged) |
|---|---|---|
| 40 | #49,234 or better | #180,024 or better |
| 44 | #16,892 or better | #14,835 or better |
| 49 | #4,435 or better | #655 or better |
Ranks are relative to each release, so a score can also move because the web around bra.in changed. OAR describes position in the public link graph; it does not predict search rankings or traffic. How OAR is computed
