Bulk Domain Authority & Backlink Checker (Ahrefs Alternative)

Check domain authority and backlinks for hundreds or thousands of domains at once. For every domain you get a domain rank (0–100), referring domains, total backlinks, dofollow vs nofollow links and their 30-day changes — as a table, CSV, Excel or JSON.

A pay-per-domain alternative to Ahrefs, Semrush and Moz for link building, SEO audits and prospect qualification. No subscription, no seat limits, no browser extension.

FAQ

Is domain rank the same as Moz DA or Ahrefs DR? No — every vendor computes authority from its own backlink index, so numbers differ between tools. Domain rank here is Serpstat's 0–100 score. Use it consistently to compare domains against each other.

How fresh is the data? It comes from a continuously updated commercial backlink index; the 30-day change fields show recent movement.

Can I get the individual backlinks? This Actor returns aggregate metrics per domain. Individual backlink lists may come as an add-on — ask in the Issues tab.
