What Is a Good Harmonic Centrality Score?

There is no universal “good” harmonic centrality score or fixed SEO threshold. The score is a raw sum that depends on the graph’s nodes, links, and coverage. It is not normalized to a standard 0–100 scale.

The rank is usually easier to compare within one release: rank 1 is the highest-ranked node in that graph. A score or rank from another release may reflect a changed graph as well as a changed domain.

Use the calculator’s release label as context. For a precise explanation, see score versus rank and why this is not a Google ranking metric.
