Methodology

Rank = position of the domain in the NetAPI Top 1M, which combines several public SEO / link-graph and traffic signals with reciprocal rank fusion so that no single source dominates. Domains are registrable domains (eTLD+1); a .io domain is any domain whose top-level domain is .io, regardless of where the site is hosted or who runs it.

The list is rebuilt every day; counts and ranks on this page refer to the current snapshot. The page exists for TLDs with at least 1,000 domains in the Top 1M.
