- PageRank rank #2,86217.2 of 30 points
Harmonic centrality is holding this score back. It measures how close opm.gov is to the rest of the web, so it rises with links from many sites that are themselves well connected. It carries 70% of the score, so it is also where a change moves OAR most.
Rank needed for a higher score
| OAR | Harmonic centrality rank (PageRank unchanged) | PageRank rank (harmonic centrality unchanged) |
|---|---|---|
| 56 | #4,865 or better | #2,505 or better |
| 60 | #1,669 or better | #206 or better |
| 65 | #438 or better | #9 or better |
Ranks are relative to each release, so a score can also move because the web around opm.gov changed. OAR describes position in the public link graph; it does not predict search rankings or traffic. How OAR is computed
