Domain authority is a score from 1 to 100, created by the SEO software company Moz, that predicts how well a website might rank compared with others. It is not a Google metric, Google does not use it, and raising the number is not the same as improving your rankings.
It can still be useful as a rough comparison tool, as long as you know what it is and what it is not. Business owners often fixate on it because it is a single, simple number. The real picture of search performance is more complicated and more useful.
What domain authority measures
Moz calculates its score from a model that looks mainly at the quantity and quality of links pointing to a site, plus other factors in Moz's own data. It is a prediction built to correlate with how sites perform in search, not a direct measurement of anything Google does.
Other tools have their own versions with different names, such as Domain Rating from Ahrefs and Authority Score from Semrush. Each uses its own data and method, so the same website can show very different numbers in different tools. A site with a score of 30 in one tool may show 45 in another. Compare like with like: use one tool consistently, and only compare your site with others measured by the same tool.
Does domain authority affect rankings?
No, not directly. Google has said publicly that it does not use domain authority, and its rankings happen at the level of individual pages and queries. What the score does reflect is something that does matter: the strength of your links. Links remain one signal among many, and a site with many good links often performs well.
That is correlation, not control. A page with a modest-looking domain score can outrank a site with a high one if it answers the search better, matches intent, loads well and suits the location. Local searches are a good example: a Hyderabad dentist with a well-managed Google Business Profile, strong reviews and relevant pages can beat a national health portal with a far higher score.
What counts as a good score?
There is no universal good number. A new site normally starts low and builds over time. Scores are logarithmic, so moving from 20 to 30 is generally easier than moving from 60 to 70. What matters is how you compare with the sites you compete against for the searches you want.
- If competitors on page one average in the 20s and you are in the 10s, links may be part of the gap.
- If you are already close to them and still not ranking, the cause is probably elsewhere: content, intent, technical issues or local signals.
- If a competitor has a very high score because of years of press coverage, do not try to match them on broad terms. Target narrower searches where you can compete.
Across industries, scores differ widely. A niche B2B manufacturer may rank well with a modest number because few competitors target its searches. A broad ecommerce category may be dominated by sites with much higher scores.
Examples of why the score can mislead
Picture two Hyderabad businesses. The first is a long-established furniture store with a high score thanks to years of press mentions, but its product pages are thin and slow. The second is a newer interior design studio with a lower score, detailed project pages, strong reviews and a well-run Google Business Profile. For the search 'modular kitchen designer Hyderabad', the second business can easily appear above the first.
The same is true in B2B. A specialised manufacturer of industrial valves may have a modest score, yet rank well for narrow technical searches because it publishes precise specifications that larger, more general sites do not. The score describes link strength in general. It does not describe how well a page serves a particular search.
A further quirk: scores can change when the tool updates its model or data, even if nothing changed on your site. A dip is not necessarily a sign of trouble, and a rise is not necessarily a sign of success.
The practical uses of a score
Used sensibly, domain authority and similar metrics help in a few situations.
- Competitor comparison. A quick sense of who you are up against.
- Prioritising link opportunities. A rough filter to avoid obviously weak sites. Relevance and real audience matter more than the number.
- Tracking trends. If your score keeps rising over a year as you earn better links, that is a sign of progress, though not proof of rankings.
It is not suited to forecasting traffic, judging an agency's work month by month, or deciding which of two pages will rank.
Why chasing the number backfires
Because the score is easy to display, some sellers promise to raise it quickly. The usual method is buying links in bulk, which is exactly the type of tactic Google's spam policies warn against. The number may move while rankings stay put, and your site may pick up risk that needs cleaning later. Our article on toxic backlinks explains what that looks like.
Likewise, buying an old domain for its score, or promising a client 'DA 50 in three months', says nothing about whether customers will find you.
What to focus on instead
If you want your site to perform better, work on the things that actually decide results.
- Pages that match intent. The right page type for each search. See search intent SEO.
- Content that is better than what ranks. More useful, clearer, more trustworthy and more specific to your audience.
- Technical health. A fast, crawlable and mobile-friendly site. Our technical SEO checklist covers the essentials.
- Earned, relevant links. Quality over quantity, as described in link building strategies.
- Brand and trust signals. Reviews, consistent business details, clear authorship, and real people behind the business.
- Local presence. For anyone serving a city, a complete Google Business Profile and local content.
As these improve, authority scores usually rise as a side effect.
Reading authority numbers in a client report
If an agency shows you a domain authority chart, ask what else is in the report. A sensible report links activity to outcomes: enquiries, calls, sales, and the searches and pages that produced them. A report built around one score tells you little about whether the business is growing. Ask what changed on the site, which links were earned and why those links matter for customers.

In short: look at the number if it helps you compare, then put it aside and get on with the work that earns enquiries. A site that is useful, fast, trusted locally and linked to by relevant sources will usually see its authority score follow.
If you are comparing your site with a competitor, look at their best-ranking pages and ask what they do better, not only at their score.
