Harmonic centrality is holding this score back. It measures how close fema.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) |
|---|---|---|
| 58 | #3,567 or better | #1,354 or better |
| 62 | #1,224 or better | #111 or better |
| 67 | #321 or better | #4 or better |
Ranks are relative to each release, so a score can also move because the web around fema.gov changed. OAR describes position in the public link graph; it does not predict search rankings or traffic. How OAR is computed
