SEO glossary
What is Domain Rating?
Domain Rating (DR) is a metric created by Ahrefs that scores the strength of a website’s backlink profile on a scale from 0 to 100. It is based on how many unique domains link to the site and how strong those linking domains are. Higher means a stronger link profile. Google does not use DR.
Related SEO terms
Domain Authority (DA) is Moz’s 1–100 score predicting how well a website might rank, based mainly on its links. Google does not use it.
A referring domain is a website that links to your site at least once. Each domain counts once, no matter how many links it sends.
A backlink is a link from another website to yours. Search engines treat backlinks as votes of trust and use them to rank and discover pages.
URL Rating (UR) is Ahrefs’ 0–100 score of the strength of one page’s backlink profile, including internal and external links.
Link buildingWhite hat
Link building is the work of getting other websites to link to yours, to earn referral traffic and the trust that helps pages rank.
Website authority checker FAQ
Is Domain Rating the same as Domain Authority?
They measure the same idea, the strength of a site’s backlink profile on a 0 to 100 scale, but each company calculates its own, so a DA checker and a DR checker give different numbers. Google uses neither. Compare sites on the same scale rather than reading one number alone.
What is a good website authority score?
It depends on the competition. A site with a Domain Rating of 30 can rank well in a niche where the top results are 20 to 35; the useful question is how you compare with the sites ranking for your keywords.
Do I need a project?
No. The SEO tools work on their own, in any market you pick. Keywords you find can be saved to a project in one click when you want to track them.
Can I share a result?
Yes. The search, the market and the open tab are all in the page address, so a link or a bookmark opens the same view. Anyone opening it runs the search with their own key; a repeat of something already looked up is served from the cache for free.
