Domain Authority Checker

Compare up to five domains — yours and your competitors — on the authority signals we can measure honestly. Registration date, age and registrar come live from the public registry (RDAP, queried at the registry for each domain ending, for example Nominet for .uk). Third-party authority scores such as Open PageRank or Moz Domain Authority appear only when the relevant provider is connected; where one is not, this tool shows no score rather than inventing a number.

Put your own domain first — the comparison reads best that way.

At a glance

What it does, what it reads, what it cannot see

Every tool on this site states its scope in the same six lines, so you know what a result means before you act on it.

You enter
Up to five domains, yours and competitors’
You get
Registration date, age and registrar for each from the responsible registry; third-party authority scores only when a provider is configured
It reads
The registry’s own RDAP record for each domain ending; provider APIs where connected
It cannot see
Links, traffic and rankings; a domain’s age says nothing about what is written about it
It takes
A few seconds per domain

How to read it

Illustrative: these domains do not exist and nothing was looked up. In a real run the registration date, age and registrar come from the registry responsible for each domain ending (Nominet for .uk), and the global rank column appears only when an authority provider is configured on this deployment; when it is not, the column is absent rather than empty. Age is one weak signal among many. A 22-year-old domain with nothing written about it is not more authoritative than a 3-year-old one that local press and directories link to.

This example is a sketch of the result’s format. The businesses in it do not exist and no lookup or model call was made; run the tool on your own details for a measured result.

How it works

What this tool measures, and what it leaves alone

Read this before you act on a result. Every tool here states its method and its limits in the same breath.

What Domain Authority actually is

Domain Authority (DA) is a metric invented and owned by Moz, a search-marketing software company. It predicts how likely a domain is to rank compared with other domains, based mostly on the quantity and quality of links pointing at it. Ahrefs has an equivalent called Domain Rating and Semrush has Authority Score — the three are calculated differently and are not interchangeable.

The most important fact about Domain Authority: Google does not use it. It is a third-party estimate, useful for comparing yourself against competitors, not a score Google awards or reads. A local business can and regularly does outrank higher-DA competitors on searches where relevance, proximity and reviews matter more than links.

What actually matters for a local business

For local search, raw domain authority is one signal among many — and often not the deciding one. Relevance (do your pages clearly cover the service and the place?), your Google Business Profile, reviews, and consistent business information across the web frequently matter more. Where authority does matter, unique referring domains — the number of different websites linking to you — is usually a more honest measure than raw backlink counts, because a thousand links from one directory are worth far less than ten links from ten local institutions.

That is why this tool leads with measurable, ownable facts — domain age, comparison against your actual competitors — rather than encouraging you to chase one proprietary number.

Questions

Common questions

Is Domain Authority a Google ranking factor?

No. Google has repeatedly confirmed it does not use Moz’s Domain Authority or any third-party authority score. These metrics are estimates of ranking ability, useful for competitor comparison only.

What is a good Domain Authority for a local business?

Context is everything. DA 25 can lead a local market where competitors sit at 10–20, and lose badly in one where they sit at 40+. Compare against the businesses that actually outrank you, not against national brands.

Why does this tool sometimes say "data unavailable"?

Proprietary metrics belong to their providers (Moz, Ahrefs, Semrush) and require licensed API access. When a provider is not connected we say so, because showing an invented number would be worse than showing none.

Does domain age affect rankings?

Not directly — Google says age itself is not a factor. But an older domain has had longer to accumulate links, mentions and trust, so it correlates with authority. It is also a useful trust check on competitors and suppliers.
