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 57 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 #2,42540.9 of 70 points
  • PageRank rank #4,23516.6 of 30 points

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