How often it is updated
The files are generated from the live catalogue, so they change whenever the list does: new sites are added, closed ones are flagged and re-checks are recorded per entry. Downloads are refreshed at least hourly. The current version is dated 6 November 2026.
How entries are researched and checked, and how the value score is worked out, is set out in the methodology. Spotted something out of date? Report it.
Read this before you use the numbers
- est. DA. est. DA is an estimate of domain authority on a third-party-style 0-100 scale, rounded to the nearest 5. It comes from our domain-facts file (source: domain-facts); it names no measurement provider and carries no measurement date. Use it to compare sites, not as a Google metric.
- Link type is what a normal listing on that domain usually gets. Sites change it without notice, so it is a starting point, not a promise.
- status says whether we checked the submission path on the site's own page. It never says a listing was approved.
