How this tool works

Two domains go head to head on Common Crawl's open web graph: their Harmonic Centrality and PageRank ranks are compared side by side to see which is more central and authoritative on the open web.

Harmonic Centrality measures how "close" a domain is to all other domains (it can reach many through few link hops), the spam-resistant metric Common Crawl uses for crawl priority; PageRank measures authority from the quantity and quality of incoming links. Both are free and open, no API key, served instantly from a local copy of the latest release (top 12M domains).
