Domain authority is a score from 1 to 100, created by the SEO company Moz, that predicts how likely a website is to rank based mostly on its backlinks. Here is the part that matters: Google does not use it. It is a third-party estimate for comparing sites, not a dial you turn to rank higher. Useful for sizing up a competitor, dangerous if someone sells it to you as a guarantee of calls.
We run our own home-service companies — a cleaning company in Tucson and an HVAC company in Sacramento — and our domain authority is unremarkable. We still rank and book jobs, because local results run on different signals. Here is what the number means, what it does not, and what to chase instead.
The score is driven largely by the quantity and quality of sites linking to yours. More links from reputable, relevant sites push it up; spammy links can drag it down.
It is logarithmic, so climbing from 20 to 30 is far easier than 60 to 70. A small local site sitting in the teens to thirties is normal and fine.
Other tools publish their own versions, like domain rating. They measure similar things with different math, so the numbers do not match across tools.
It is most useful for comparison. If a competitor outranks you and has a much higher score, links may be part of the gap. The absolute number alone tells you little.
This is the misunderstanding that costs small businesses money. Google has said plainly it does not use domain authority or any single site-wide authority number. The practical consequences:
If you run a local service business, here is where the same effort pays off in actual calls:
Domain authority is not useless. It is just narrow. It is worth checking when:
Beyond that, do not let a third-party score set your strategy. A small operator in a quiet market can rank with a low score and a strong profile. Calls are the only number that pays the bills.
We do not sell domain authority. We do the work that actually produces local calls: a complete profile, real reviews, service and city pages, and attribution that shows which page brought each lead. If a number goes up along the way, fine, but calls are what we measure.
Our Grow in Google plan is $597/month — the site, the monthly content engine, profile management, and attribution, month-to-month, and you own everything. See SEO for home services, the SEO glossary, or our take on what local SEO costs.
We don't post stock testimonials. On a 15-minute call we screen-share the real dashboards behind our own businesses — live leads, rankings, and the exact page that produced each one. See the proof →
No. Google has said it does not use domain authority or any single site-wide authority score. The number comes from Moz, not Google, so raising it does not directly raise your rankings.
A domain authority in the teens to low thirties is common and fine to rank locally. Local results lean on your profile, reviews, and proximity. Compare against your direct competitors, not national publishers.
Earn a few quality, relevant links and publish content worth linking to. For a local business, that effort pays off more through your Business Profile, reviews, and city and service pages.
