Free Domain Authority Checker

Our domain authority checker pulls a domain's authority signals from DataForSEO in one lookup: a 0-1000 domain rank, the number of referring domains, total backlinks, the dofollow-to-nofollow split, and an estimate of monthly organic traffic. Enter a domain and you get a single readout you can use to size up a site, yours or a competitor's, before a link campaign or an acquisition.

The workflow is one step: enter a bare domain (we strip the protocol and www for you) and the tool fetches the backlink summary and the organic-traffic overview in parallel, then renders the rank with a proportional bar plus supporting metric cards. Results are cached for 24 hours, so popular domains return instantly on a repeat lookup.

For Link Builders

Our tool helps you vet a prospect domain before you invest in outreach. Check the rank and referring domains to:

• Compare prospect domains against each other on a single scale
• Spot thin profiles (few referring domains) before spending on a placement
• See the dofollow ratio so you know how much equity a link could pass

For SEO Analysts

Our tool helps you benchmark a site against competitors fast. Pull the rank and traffic estimate to:

• Size up where a domain sits relative to rivals you already know
• Pair the rank with the organic traffic estimate for a fuller picture
• Validate a quick read before committing to a paid platform's deeper data

Why Use Our Domain Authority Checker

• One readout, real data: Rank, referring domains, backlinks, dofollow ratio, and traffic estimate come from DataForSEO in a single lookup, not a thin sample or a guess.
• Honest about the metric: The rank is DataForSEO's proprietary 0-1000 score, not Ahrefs Domain Rating or Moz Domain Authority. We say so plainly so you read it as a relative-comparison signal, not a borrowed industry number.
• Built for comparison: Because every domain is scored on the same 0-1000 scale, you can line up a prospect against a competitor and see the gap at a glance.
