About the Bulk Domain Authority Checker
A domain authority checker estimates how strong a website is in search, based on how many other sites link to it and how important those sites are. Paste up to 100 domains to see each one's OpenPageRank score from 0 to 10, its global rank and its referring domains, sort them and download a CSV. It is useful for comparing competitors, checking link partners and judging guest-post sites.

Is this the same as Moz Domain Authority?
No. Domain Authority (DA) is a 0-100 score owned by Moz, and Domain Rating (DR) belongs to Ahrefs. This tool shows OpenPageRank, a 0-10 score calculated from the public Common Crawl web graph with the PageRank method. All of these measure the same idea, the strength of a site's links, but they are calculated differently, so the numbers can't be converted into each other.
What is a good score?
The scale is logarithmic: moving from 2 to 3 takes far fewer links than moving from 8 to 9. New websites usually start near 0, small established sites often score 2-4, well-known brands 5-7, and only the largest sites on the internet reach 9 or 10. Compare a site with others in the same niche rather than with the biggest websites.

Frequently asked questions
How do I check the domain authority of a website?
Paste the domain into the box and click Check authority. You can check up to 100 domains at once.
Where do the scores come from?
From OpenPageRank, which calculates authority from the Common Crawl web graph, a public crawl of billions of web pages. The scores are updated monthly.
How can I increase my score?
Earn links from respected websites in your field: useful content, listings in quality directories, guest articles and mentions in the press. Links from many different sites count more than many links from one site.
Why does a site show Not found?
Very new or very small sites may not have enough links in the web graph yet to receive a score.
