Bulk Domain Authority & Backlink Checker (Ahrefs Alternative)

Check the authority of hundreds or thousands of websites in one run. Paste a list of domains or URLs and get each site's domain rank (0–100), referring domains, backlinks, dofollow vs nofollow split, spam score and optional 30-day changes, as a table you can export to CSV, Excel or JSON.

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

What you can do with it

• 🔗 Qualify link-building and guest-post prospects before you email them: keep only sites above a minimum domain rank (minDomainRank).
• 🏷 Screen expired and auction domains before you buy: referring domains, dofollow ratio, spam score and broken backlinks in one row.
• 📊 Benchmark a client against competitors in a single run.
• 🧾 Enrich a list of websites (leads, partners, publishers) with authority columns.
• 📈 Monitor link growth: schedule a weekly run with includeChanges to see new and lost referring domains.

FAQ

Is domain rank the same as Moz DA or Ahrefs DR? No. Every vendor computes authority from its own backlink index, so the numbers differ between tools. Use one score consistently to compare domains with each other.

Where does the data come from? From a large commercial backlink index that is crawled continuously. Nothing is scraped from Ahrefs, Semrush or Moz.

Can I get the individual backlinks? Use the Backlink Checker: every backlink with source page, anchor and dofollow status, plus a competitor link gap.
