A domain rating is a number between 0 and 100 that describes the strength of a site's backlink profile, and it is the most-quoted figure in link building for a reason that has little to do with its accuracy: it is a single number, it is free to look up, and it lets two strangers agree on a price in one message. Whether it predicts anything you care about is a separate question, and the honest answer is "one thing, weakly, and not the thing most people use it for." (Disclosure: published by [BidSurvivor](https://bidsurvivor.space), which displays its own domain rating on the site, so read the section where that gets examined with appropriate suspicion.)

## What the number actually measures

Every major SEO tool has its own version — Ahrefs calls it Domain Rating, Moz calls it Domain Authority, Semrush calls it Authority Score — and none of them is a Google metric. Google does not publish one and has said repeatedly that it does not use these scores. They are third-party estimates of one thing: **how many other sites link to you, weighted by how many sites link to those.**

Two consequences follow immediately, and both are widely ignored.

**It is logarithmic.** Moving from 0 to 20 takes a handful of decent links. Moving from 60 to 80 takes thousands. A site at DR 18 and a site at DR 36 are not "half as strong" — the gap is far larger than the numbers suggest, and the gap between 70 and 80 is larger still.

**It says nothing about traffic.** A site can accumulate links from directories, aggregators and profile pages, register a respectable score, and receive almost no visitors. The reverse also happens: sites with strong traffic and weak link profiles are common in any niche where the audience arrives from a community rather than from search.

## The correlation that exists, and its limits

There is a real relationship between link profile strength and search visibility. Links have been a ranking input since PageRank and remain one. Sites with many good links do, on average, rank for more things.

But "on average, across millions of sites" is a much weaker claim than the one people make when they buy a link. Two things break the inference at the level of an individual site:

**Relevance dominates at small scale.** A link from a DR 30 site in your exact niche routinely outperforms a DR 70 link from a general directory, because the first one sits in a context Google can read as topical and the second sits in a list. Ahrefs' own [study of search traffic](https://ahrefs.com/blog/search-traffic-study/) found that 96.55% of pages get no traffic from Google at all — and a large share of those pages have links pointing at them.

**Search is sending fewer clicks anyway.** Whatever a strong link profile bought two years ago, it buys less of now, because more queries resolve without a click. We went through the arithmetic in [where small sites get traffic after AI Overviews](/blog/where-small-sites-get-traffic-after-ai-overviews), and the short version is that ranking and receiving visitors have come apart.

## Where the number is genuinely useful

Three uses that survive scrutiny.

**As a rough filter against obvious junk.** A site at DR 2 with a thousand outbound links is a link farm. The number is a fast way to see that. It is a floor test, not a quality score.

**As a negotiating unit.** When two people who have never met need to agree that a trade is roughly fair, a shared public number does that job in one line. It does not need to be accurate to be useful for this; it needs to be public and hard to fake.

**As a trend on your own site.** Your own rating moving up over six months means links are accumulating. That is worth knowing. Comparing your absolute number to somebody else's is worth much less.

## Our own number, examined

We display a domain rating on this site, which makes the argument above slightly awkward, so here is the position stated plainly.

The number is real, it is fetched from a third party rather than typed in, and it is small — this is a young domain. It is on the site for the second use above: people evaluating whether to trade a link with us can see it without asking, and a public number that anybody can verify is better than a claim in an email. It is not evidence that a link from here will send anybody to your site.

The thing we publish that *is* evidence of that is different and more specific: every ad slot's card opens and click-throughs, counted separately and shown on the front page and on each brand's own page. That is a record of humans arriving somewhere, which is the fact a rating only gestures at. The same distinction drives the [backlink tracker](/tools/backlinks) — it joins the links that exist to the links that have ever sent a visitor, because those are different sets and almost nobody puts them in the same table.

## The question worth asking instead

Before accepting or paying for a link, the useful questions are not about the rating:

1. **Would a reader of that page plausibly want what I sell?** If not, the link is decoration.
2. **Does that page get read?** A link on a page nobody visits is worth whatever a link on a page nobody visits is worth.
3. **Has that site ever sent anybody anywhere?** This is answerable from your own referrer log after the fact, and it is the only one of these that produces a number you own rather than one you looked up.
4. **Would I want this link if scores did not exist?** The most reliable filter on the list.

A domain rating answers none of those. It is a proxy for the first half of the first one, and it has become the whole conversation because it is the only part that fits in a table. If you take one thing from this: [a link that never sent a visitor](/blog/backlinks-that-never-sent-a-visitor) is not a weaker version of a good link, it is a different thing entirely, and no rating will tell you which one you have.
