How can I find my domain SEO power? Score it out of 100 with the checker below: paste any domain and the number comes back in about a second.

The figure above is Ahrefs Domain Rating (DR), pulled live from the official Ahrefs public API rather than modelled or guessed, so it is the same number an Ahrefs subscriber sees on the same domain. One site at a time, or paste up to twenty into the bulk tab and export the lot as CSV. No signup, no API key, no credit counter.

What the number is, and what it is not

It is a 0-100 measure of backlink strength only. It reads how many unique domains link to a site, weighted by how strong those linking domains are themselves.

It does not read content quality, traffic, revenue, or whether you will outrank anyone. A site at 60 built on bought links and a site at 30 built on editorial links score the way they do for reasons the number cannot show you.

The scale is logarithmic, which is the part that catches people out. Going from 70 to 80 takes vastly more link acquisition than going from 10 to 20. Early points are cheap and late points are brutal.

I have used Ahrefs since 2014 across 100+ sites, and this is the first thing I check on a link prospect or a competitor. It takes a second and it rules out the obviously weak. What it never does is settle the question: before acting on a score I open the referring domains and read them, because two sites with identical numbers can have completely different profiles behind them.

Reading the bands

“Good” is always relative to your niche. A local plumber at 30 can outrank a general directory at 60 for local queries. With that said, a practical frame:

RangeStrengthTypical profile
0-10Very weakNew site, almost no links. Hard to rank competitively.
11-30WeakEarly-stage with some links. Can win low-competition terms.
31-50ModerateEstablished niche site. Competitive on mid-tail.
51-70StrongAuthority in its space. Can compete on head terms with good content.
71-100Very strongMajor publications and national brands.

This is not Moz’s Domain Authority

The two get used interchangeably and they are not interchangeable.

Both sit on a 0-100 logarithmic scale and both estimate link strength, but they run on different crawlers, different link indexes and different scoring functions. A site can be 45 on one and 30 on the other, and neither is wrong. Neither is a Google ranking factor.

MetricVendorBased on
Domain Rating (DR)AhrefsReferring domains weighted by their own DR
Domain Authority (DA)MozLink count, MozRank, MozTrust
Authority Score (AS)SemrushNumber and quality of referring domains
PageRankGoogleThe real link graph, never published

If you specifically need the Moz figure, this is the wrong tool and you want Moz’s own checker. I also built a Chrome extension that shows the Ahrefs score for the tab you are on and for every domain in a SERP, if checking one URL at a time is the friction.

Check the page score too, not just the domain

Domain-level strength describes the whole site. URL Rating (UR) describes one page.

When you are evaluating an actual link opportunity, the page matters more than the domain. A site at 70 linking from a UR 5 orphan page passes less than a site at 50 linking from a UR 40 pillar article. Use the domain figure for prospecting and competitor research; check the page figure before you value a specific link.

A drop here is rarely what cost you traffic

When rankings fall this is the first number people check, and it is almost never the cause.

It is a relative score on a logarithmic curve, so it moves when Ahrefs recrawls, when the sites linking to you get reassessed, and when the rest of the index shifts around you. A point or two of movement with no change to your backlinks is normal and means nothing.

What is worth investigating is a fall of five or more, which usually means you genuinely lost referring domains. Check the referring domains graph before anything else.

And if the score held steady while traffic fell, the cause is somewhere else entirely. Match the date against the Google penalty checker before you go looking for links to build.

How to actually move it

It rises when more strong sites link to you. There is no shortcut, and no tool sells one.

  1. Build things worth linking to. Original research, data studies, free tools, genuinely complete guides. This page is the example: a working tool earns links from people who reference it.
  2. Guest post on relevant sites above your level. One link from a relevant site at 60 moves the needle more than fifty directory links at 5.
  3. Digital PR. Get your data cited in industry news and roundups. One national publication outweighs a few hundred submissions.
  4. Reclaim lost links. Check for lost referring domains and reach out when a page that linked to you was moved or rewritten.
  5. Fix broken backlinks. Find external links pointing at your 404s and redirect them to live pages, so the authority is not thrown away.

How to use it

  1. Enter a domain (ahrefs.com) or a full URL.
  2. Click Check DR. It calls the Ahrefs public API live.
  3. You get the 0-100 score, a gauge and a plain-English reading.
  4. For more than one, use the bulk tab: up to twenty, checked sequentially to respect the rate limit, with CSV export.

The API is free and rate-limited by IP. For full backlink data, historical trends or genuine bulk work, you need an Ahrefs plan.

Frequently asked

Questions About This Article

Is this tool really free?

Yes. It runs on Ahrefs' official public domain rating API, which is free and needs no API key, so there is nothing to sign up for and no credit system. The only ceiling is that API's rate limit, applied per IP address. Bulk mode checks domains one after another rather than all at once for that reason.

Is domain authority the same as Domain Rating?

No, and it matters here. Domain Authority (DA) is Moz's 0-100 score; Domain Rating (DR) is the Ahrefs equivalent. This tool returns DR. People use that phrase for either one, because it went generic for link strength years ago, but the two are computed from different link indexes and will not match. A site can sit at DR 52 and DA 41 and neither number is wrong.

How often does the score update?

Ahrefs crawls continuously, and a change in referring domains usually shows within a few days to a few weeks. This tool always asks the API live, so you see the current figure rather than a cached one. Historical trend lines and the backlinks behind the score need an Ahrefs account.

Why does my new site show 0?

Every domain starts at 0 and the scale is logarithmic, so the first few points need the most links relative to what you have. Sitting at 0-5 for the first few months is normal without active link acquisition, and it is not a signal that anything is broken.

Can I check a subdomain separately?

Not with this tool. The score is measured at domain level, so entering blog.example.com generally returns the figure for example.com. Subdomain-level link analysis needs Ahrefs Site Explorer on a paid plan.

Does the score affect Google rankings?

Not directly. It is a third-party metric, not a Google signal - Google uses its own internal PageRank, which has never been public. What the score measures does correlate with rankings, because Google genuinely does use backlinks, so sites with strong link profiles tend to score well and rank well for the same underlying reason. It is a proxy, not a cause.
