Bulk Domain Authority Checker

What the bulk domain authority checker shows

One row per domain with everything Moz reports for it: Domain Authority and Page Authority, the spam score, the number of linking domains and external links to the domain, to its www subdomain and to its home page, and the change in DA over 12 and 36 months. For names DomCop has listed, the row comes from the Moz data DomCop fetched when the name was listed. For other names it comes through the Keywords Everywhere link-metrics service.

How to read the table

• DA with linking domains behind it is the profile of a domain with links from real sites. A DA of 30 on 20 linking domains has been pushed up by a few strong links and can fall as fast as it rose.
• External links far above linking domains means site-wide links: a handful of sites linking from every page. Judge the domain on the linking domains count.
• Spam score above 30% deserves a look at the backlinks and the domain history before you buy. Above 60%, DomCop flags the name.
• A falling DA over 12 months usually means the site went down and its links are being removed. A rising DA on an expired domain is rarer, and worth a look at who is linking and why.

From a list to a purchase

Checking names you already have is the slow way round. DomCop's expired domains list shows these columns, plus Majestic Trust Flow, Ahrefs DR and the rest, for every name about to expire or drop, so you filter the market down to a shortlist instead of looking names up one list at a time. The high DA expired domains and high Trust Flow searches are the usual starting points.

Frequently asked questions

Where do the numbers come from? All of them from Moz. For a name DomCop lists (expiring, expired or archived), from the Moz row DomCop fetched when the name was listed. For other names, from the Keywords Everywhere link-metrics service, which caches Moz data. A name neither source knows shows a dash.

How many domains can I check? Visitors can check 25 names per batch and 100 a day per connection, with a reCAPTCHA after the first 20. DomCop members get 100 per batch and 1,000 a day, and every name in the DomCop lists already carries 90+ metrics on its row, Majestic and Ahrefs included.

What is the difference between Domain Authority and Page Authority? Domain Authority (DA) scores the whole domain from 1 to 100 on how likely it is to rank. Page Authority (PA) scores one page, here the home page. A domain with a DA well above its PA has its links spread over inner pages; a PA above the DA means the links point at the home page.

What do the link counts mean? Linking domains is the number of different websites that link to the domain, counted once each. External links counts every link from outside the domain, so one site linking 500 times counts 500. The "www" columns count links to the www version only; the "page" column counts links to the home page only. A high link count with few linking domains usually means site-wide links from a handful of sites.

Can I export the table? Not from this page. DomCop members export the full lists with every metric as CSV from the domain search.
