Methodology

Live facts, checked on every visit

For any domain, on every page load, StatsMyWeb checks:

• DNS records (A, AAAA, MX, NS) over DNS-over-HTTPS.
• HTTPS reachability — whether the domain answers a request over HTTPS right now, and with what status code.

These are shown for every domain, whether or not StatsMyWeb has any other data about it, and they are never cached: what you see is what the domain answered at the moment you asked.

Connectivity rank

Where it exists, a domain page also shows a connectivity rank: how connected the domain is to the rest of the web, computed from Common Crawl’s open hyperlink graph — a periodic, independently published snapshot of how pages across the web link to each other.

The figure shown is harmonic centrality: a domain’s position, out of every domain in that snapshot, by how well-connected it is within the graph. A lower position number means a more connected domain. This is the same family of metric search engines have historically used to estimate a site’s structural importance in the web graph — it says nothing about the quality or accuracy of a site’s content, only about how many other sites link to it, directly or through short paths.

The current site runs on the cc-main-2026-jul-aug-sep snapshot: 133,241,980 domains.

What is not covered yet

StatsMyWeb does not yet have connectivity data for every domain that exists — the underlying graph is enormous, and importing all of it is a much larger undertaking than a first version needs. A domain missing connectivity data still gets a page with its live DNS and HTTPS facts; it is simply not yet part of the search-indexable set, because a page made only of generic, easily-reproduced facts earns no place in search results on its own. As more of the graph is imported, more domains gain this data.

StatsMyWeb does not run its own web crawler, does not store or reproduce the content of the pages it describes, and is not affiliated with any domain it shows data for.
