What 36 means
Top 1% of the web graph. A strong small or specialist site: it takes a steady stream of independent links to get here.
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 36 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 #93,28627.2 of 70 points
- PageRank rank #473,7059.1 of 30 points
PageRank is the weaker signal here. It rises with the number and weight of links pointing at ireff.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) |
|---|---|---|
| 37 | #87,690 or better | #410,043 or better |
| 41 | #30,086 or better | #33,790 or better |
| 46 | #7,900 or better | #1,491 or better |
Ranks are relative to each release, so a score can also move because the web around ireff.in changed. OAR describes position in the public link graph; it does not predict search rankings or traffic. How OAR is computed
