What is "website authority"?
"Website authority" is an SEO concept that refers to the "strength" of a given domain.

Some people call this "domain authority," which is not to be confused with the Domain Authority (DA) metric from Moz. When we talk about domain authority, we're talking about a general SEO concept that's synonymous with "website authority".

Here at Ahrefs, we have a website authority metric of our own called Domain Rating. It runs on a scale from zero to a hundred. The higher a website's Domain Rating (DR), the stronger and more authoritative it is.

The free tool above shows your website's "authority" as calculated by Ahrefs (i.e., Domain Rating).

How we calculate our Domain Rating (DR) score
Domain Rating (DR) looks at the quantity and quality of external backlinks to a website.

Here's how we calculate this metric in simple terms:

Look at how many unique domains link to the target website;

Look at the "authority" of those linking domains;

Take into account how many unique domains each of those sites link to;

Apply some math and coding magic to calculate “raw” DR scores;

Plot these scores on a 100-point scale

Domain Rating doesn't take into account any other variables like link spam, traffic, domain age, etc.

Why the "authority" of your domain matters
Google representatives consistently deny the use of "domain authority" as a ranking factor. But according to Google's John Mueller, they do have a sitewide score that "maps to similar things."

Plus, when we studied the correlation between Domain Rating (DR) and keyword rankings for 218,713 domains, we found that the two correlate well.

This makes Domain Rating (authority) a useful metric by which to estimate a website’s ability to get organic traffic from Google.

Disclaimer: This is a correlation study. It does not prove causation.

What is a good Domain Rating (authority) score?
Generally speaking, the higher the "authority" of your domain, the better.

But it's important not to judge Domain Rating in absolute terms. That's because Domain Rating is a relative metric by definition. It's not possible to say that a Domain Rating of 30 is good, or 50, or 60, or 70. It's all relative.

Here's a general rule of thumb:

Your Domain Rating (authority) is good if it's higher than or comparable to similar sites.

How to improve your Domain Rating (i.e., "authority" score)
Getting backlinks from more unique websites (referring domains) is the only way to improve your website's Domain Rating (authority) score.

But improving your site's "authority" should never be your primary goal.

You should instead focus on earning backlinks from strong pages on reputable sites in your industry to the pages that you want to rank in Google. That's because there's a clear correlation between the number of referring domains to a page and the amount of organic traffic it gets.
