What Is a Good Domain Authority?

A good domain authority is any score that clears the sites you actually compete with, not a universal number you can circle on a chart. Domain authority is a third party metric scored from zero to one hundred, built by Moz to estimate how likely a site is to earn visibility, and it is worth saying plainly that Google does not use it.

So the honest answer to what is a good domain authority depends entirely on your competition. A score in the twenties can be more than enough in a quiet local niche, while that same score is invisible in a field crowded with national publishers. Aim at the gap between you and the sites that already win visibility for your terms, not at an arbitrary milestone someone put in a blog post.

What domain authority actually measures

Domain authority is a prediction, not a measurement of anything Google rewards directly. Moz trains a model, largely on the size and quality of a site's backlink profile, then compresses the result onto a zero to one hundred scale so it is easy to read at a glance.

The scale is logarithmic, which matters more than it sounds. Moving from ten to twenty is ordinary. Moving from seventy to eighty is the work of years and a large volume of earned links. That curve is why a mid-range score is normal and healthy for most businesses, and why fixating on a round number sets a target that means very little.

None of the major tools can see Google's actual link graph. Each one builds its own index by crawling the web itself, so every authority score is an educated approximation of a system no outside company has full access to. Useful for direction, but always an estimate.

Why there is no universal good number

Authority only means something next to a reference point. The same figure can be strong or weak depending entirely on who you are up against.

• In a local service market, many competitors sit in the teens and twenties, so a modest score is already competitive.
• In crowded commercial or editorial markets, the sites you are chasing may sit far higher, and reaching parity takes sustained link earning over time.
• A brand new domain starts near the floor by default. That is expected, not a problem to panic over.

Pull the scores of the handful of sites already earning visibility for the terms you want. Their range is your real benchmark. That one comparison tells you more than any article claiming a specific number is good or bad.

The comparison also keeps expectations sane. If the sites you want to displace have spent a decade earning coverage, closing that gap is a long project, and any agency promising to leapfrog it quickly is selling you something that does not exist.

Domain authority is not a Google ranking factor

This is the part most people get wrong. Google has stated plainly and repeatedly that it has no single domain authority score of its own. Moz, Ahrefs, and Semrush each publish a competing estimate, called Domain Authority, Domain Rating, and Authority Score, and the three rarely agree because they crawl different link indexes and weight them differently.

Treat these numbers as weather reports, not the climate. They are useful for spotting trend direction and sizing up competitors. They are not a dial Google reads, and nudging one of them upward is not the same as earning the thing it tries to approximate, which is genuine trust signaled by other credible sites linking to you.

Does domain authority matter for AI search?

AI answer engines pull from sources they treat as trustworthy, and the same link based signals that feed a domain authority score also tend to track with being cited in AI generated answers. That does not mean raising a third party number earns you citations. It means the underlying work, earning references from sites that are themselves trusted, is what makes you quotable to both traditional search and AI assistants. We build toward that reference worthiness directly, not toward the proxy.

What to track instead of one score

• The specific terms you earn visibility for, and whether the visitors they bring are qualified.
• The quality and relevance of the sites linking to you, not the raw link count.
• How the pages already earning visibility for your terms are built, so you can see what the field actually rewards.
• Conversions and leads, because authority that never turns into business is a vanity figure.

How we treat authority when we build

We perform SEO and AI search optimization only on sites we build, so authority work starts with the technical foundation that makes links worth giving rather than chasing a score for its own sake. Clean architecture, fast pages, and content worth citing do more for long-term standing than any metric dashboard.

Because we take one client per industry per city, we are never aiming two competitors at the same market, so the authority we help you build is not quietly cancelled out by a sibling account across town.
