Domain Rating by Ahrefs

DR 0–9

New

Few or no sites link here yet. Most new launches start in this range.

DR 10–29

Growing

A handful of referring domains. Typical for early products and side projects.

DR 30–49

Established

A solid link profile. Pages on this site can rank for competitive terms.

DR 50–100

Strong to authority

One of the most linked-to sites on the web.

What is Domain Rating?

Domain Rating (DR) is a score from 0 to 100 that Ahrefs uses to describe how strong a website's backlink profile is. It counts the unique domains linking to a site, weighs each by its own DR, and divides that link equity among all the sites it links to. The scale is logarithmic, so climbing from 70 to 80 takes far more links than from 10 to 20.

DR is not a Google ranking factor, but it tracks closely with what Google rewards: links from many independent, trusted sites. That makes it a quick way to compare your site with competitors and to judge whether a site is worth getting a link from.

How to increase your Domain Rating

DR goes up when more unique domains link to you. Ten links from ten different sites help far more than ten links from one. Practical ways to earn them as a maker:

  • List your product on free directories that give a followed link, starting with AZN8.
  • Write launch posts and share them in communities where your users are.
  • Publish integration and partner pages that the other side links back to.
  • Contribute guest posts, podcast appearances, or open source with a link home.
  • Create free tools or data that others want to cite.

Skip paid link packages and private blog networks. They can move DR briefly, but search engines discount or penalize them. Our free directory catalog lists more than a hundred verified places to submit a product for free.

Get a followed link and join the leaderboard

AZN8 is a free directory for SaaS, startups, and AI tools. Every listing gets its own page with a plain followed link to your site: no redirect, no nofollow, and no badge to put on your site. Your product shows up on this leaderboard within a day.

Frequently asked questions

What is Domain Rating (DR)?

Domain Rating is an Ahrefs metric that scores the strength of a website's backlink profile on a scale from 0 to 100. It looks at how many unique domains link to a site and how strong those linking domains are themselves. Higher means a stronger link profile.

Is this Domain Rating checker free?

Yes. Checking a domain is free, needs no account, and has no daily quota for normal use. Ratings come from the free Ahrefs Domain Rating API and are cached for 24 hours.

What is a good Domain Rating?

It depends on your competitors more than on a fixed number. As a rough guide, most new sites sit below 10, early products between 10 and 30, established SaaS brands between 30 and 70, and household names above 70. Compare yourself with the sites ranking for your keywords.

How do I increase my Domain Rating?

Earn links from more unique, relevant websites: launch posts, guest articles, integrations and partner pages, podcasts, open source, and free product directories that give a followed link. Avoid paid link schemes and private blog networks, which search engines penalize.

How does the AZN8 DR leaderboard work?

Every live listing on AZN8 is ranked by the current Domain Rating of its website. Ratings refresh every 24 hours, and new listings join the board within a day. Listing is free, so you can add your product and track its DR here.

Is Domain Rating the same as Domain Authority?

No. Domain Rating (DR) is made by Ahrefs and Domain Authority (DA) by Moz. Both estimate link strength on a 0 to 100 scale, but they use different link indexes and formulas, so the numbers for the same site usually differ.

Why can't I check a subdomain like my-app.vercel.app?

A rating for a shared host such as vercel.app, github.io, or netlify.app describes the whole platform, not your product, so those are not rated. Use your own domain for a meaningful DR.
