What is domain authority?
Domain authority is a score from SEO software indicating how strong your backlink profile is. It is not a metric from Google.
Tools like Moz, Ahrefs and Semrush give your domain a score between 0 and 100 based on the number and quality of links to your site.
Google doesn't use this score. It's a tool to compare yourself with competitors, not a goal in itself.

Why it matters
Handy for assessing how tough a keyword is for you: if the top ten only features strong domains, you'll need authority before you can compete.
Also useful for link building: it helps you assess whether a link actually adds value.
How we approach it
We don't report a standalone authority score as a goal. We report rankings, traffic, and enquiries — and only use authority to determine where we can realistically win.
Agencies that sell you an authority score as a result are selling a number your customers never see.
Frequently asked questions
What is a good score?
For local SMEs, 20 to 35 is already strong. Always compare yourself with your direct competitors, not national brands.
Can I buy my score?
There are providers who try with link packages. That raises a number and lowers your credibility.
