Bulk Domain Authority Checker
A bulk domain authority checker compares how strong several websites are by their links. This free tool takes up to 10 domains and shows, for each, a link-based rank from 0 to 1000, the number of referring domains and the number of backlinks, using live data from DataForSEO. It is built for outreach lists, competitor checks and link buying decisions.

About this tool
When you build a list of sites for outreach, compare competitors, or judge a guest post offer, checking one domain at a time is slow. A bulk check puts the numbers side by side so the strong sites stand out. The most useful number is the count of referring domains, the different sites that link to the domain, because it is hard to fake and tied to how search engines see the site.
Enter up to 10 domains, one per line. For each, the tool asks DataForSEO for the link summary and reports its rank on a scale from 0 to 1000, the referring domains, the backlinks and the number of broken backlinks. Answers are cached for 24 hours and shared with our domain authority and backlink checkers, so repeat checks are fast.
The rank is DataForSEO's own link-based score. It is not Moz Domain Authority, Ahrefs Domain Rating or any Google metric, and the numbers from different vendors cannot be compared with each other. Use one tool consistently, compare like with like, and treat small differences as noise. Very new or small sites may have no data yet, and the tool says so instead of showing zero.
Frequently asked questions
Is this the same as Moz Domain Authority?
No. Domain Authority is a Moz metric that only Moz can calculate. This tool shows DataForSEO's link-based rank from 0 to 1000 together with referring domains and backlinks. They answer the same question, how strong is this site's link profile, but the numbers are not interchangeable.
Which number matters most when comparing domains?
Referring domains, the number of different sites linking in, is the most reliable guide. Total backlinks can be inflated by sitewide links from a single site. Look at both, and compare the domains you are checking with each other rather than judging a number in isolation.
Why does a domain show no data?
The data source may not have crawled enough of the web to see links to a very new or very small site. A missing result is not a penalty. Check again after the site has been live and linked for a few weeks, or look at its pages in Search Console if you own it.
How often is the data updated?
The data source refreshes its link index continuously. Our tool keeps each answer for 24 hours to control costs and keep results consistent for the day. Check back the next day to see any change, and do not expect large movement from one day to the next.
