What's the Domain Rating?

Get a link-authority score from 0 to 100 for any domain — our own measure of link-profile strength, built from our crawler and backlink database. See the number of referring domains, total backlinks and the dofollow/nofollow split, plus the data freshness date. Our own metric, our own database — no external paid APIs.

Computing the rating…
Looking up the domain and collecting its link profile…
This usually takes a few seconds — we build the domain's link graph and compute the authority passed through our database.

How it works

We score a domain by its link profile — the same way search engines do: one strong link from an authoritative domain outweighs a hundred weak ones.

1

Enter a domain

Your site or a competitor's. No account and no access to the site needed — we pull the data from our own backlink database.

We build the link graph

We count unique referring domains, not the raw number of links: a thousand links from one domain ≈ the weight of a single donor.

We weigh donor authority

Authority flows recursively through the graph (a PageRank-style model). We account for dofollow/nofollow and the dilution from donors with thousands of outbound links.

We normalise to a 0–100 scale

The raw value is mapped onto a logarithmic 0–100 scale relative to the strongest domain in our database. Going from 20 to 30 is easy; from 80 to 90 is almost impossible.

Domain Rating is YuSMP's own metric, computed with our methodology and calibrated against our own backlink database. It is not a reprint of Ahrefs DR: we do not guarantee one-to-one comparability with external services, and data for new domains appears only after our crawler visits them. The result is indicative.

Why the scale is logarithmic

Link authority is distributed extremely unevenly: a small number of domains carry a huge mass of links, while most have only a handful. A linear scale would squash the whole web into the bottom third, and the difference between a site with 10 and one with 10,000 donors would be invisible.

So we map a domain's raw strength onto a logarithmic 0–100 scale. The first links produce fast growth, and each step higher up gets harder to earn — exactly how it works with search engines.

  • We count unique referring domains, not the raw number of links
  • Authority flows recursively through the graph until it stabilises
  • nofollow links count with a heavily reduced weight
  • A donor with thousands of outbound links passes less to each
