What domain authority is and how to raise it

"Domain authority" is one of those terms that sound complicated but mean something simple: how strong the websites linking to yours are. The more respected sites mention you with a link, the more likely Google is to trust you and show you higher. The short version: it is a score from SEO tools, not from Google; you can check it for free; a new site starts at zero; and you raise it with real links from partners, industry sites and media, not with bought packages.

What domain authority actually is

Domain Authority (DA) is a score from 1 to 100 that the company Moz calculates for every website. It tries to predict how well a site would rank, looking mainly at the links pointing to it: how many there are and how strong the linking sites are [1]. Ahrefs has a similar score, Domain Rating (DR) from 0 to 100, which measures the strength of a site's backlink profile [2]. Semrush has its own, Authority Score [3].

The important part: these are not Google's numbers. Moz itself says Domain Authority is not a Google ranking factor [1]. Google has its own, far more complex signals. But these scores are useful because they measure something Google really does look at: who links to you. Google describes links from other sites as a way to learn that your content is useful and worth attention [4].

So think of domain authority as a thermometer. You do not chase the number for its own sake; it shows whether your website is earning trust on the web.

What a good number is

There is no "good" number on its own. The scores are relative: compare yourself with competitors in the same town and industry, not with Facebook or a news site.

• New website: 0–5. Completely normal. Nobody has mentioned you yet.
• Local business with a few real links: 5–20. Often already more than most competitors.
• Established brands, media, big directories: 40+. You do not need to get here to reach page one for "your service + town".

If your competitors are at 10 and you are at 2, you know what is missing: links.

Which links really help

Not all links are equal. A link is worth more when:

• The site is real and respected: it has its own visitors, writes about real things and others cite it too.
• The topic is related: a materials supplier linking to a tradesperson makes more sense than a random car blog.
• Someone mentioned you on their own, in the text, for a reason, not in a list of 500 links.
• The site is local, if your business is local: the municipality, local media, an industry association.

Links from social media profiles and most directories are usually marked so that they do not pass ranking strength [6]. They still help discovery and bring people, but they do not raise domain authority. The real strength comes from websites that choose to recommend you.

How to raise domain authority: practical ways

1. Partners and suppliers. Ask the companies you work with to add you to their "Partners" page. Offer the same in return. These are the easiest real links.
2. Industry associations and chambers. Membership often includes a profile with a link in their directory.
3. Local media. A new opening, an interesting project, useful advice from an expert. Local news sites look for stories, and one article with a link is among the strongest signals.
4. Reviews for suppliers. Write a testimonial for a tool, software or material you use. Many companies publish customer testimonials with a link.
5. Guest articles or expert quotes. An industry blog or local site may publish a useful piece by you. Write for the readers, not for the link.
6. Sponsorships and events. A local team, a festival, a charity: your name and link end up on their site.
7. Content others want to cite. A price list, a comparison, a guide, before-and-after photos. When you have something useful, others link to it by themselves. How to connect your own pages to each other: internal linking and SEO.

For the first, quick steps with a new website (social networks, Google profile, directories), see got a new website? here is how to help it climb in Google.

What to avoid

Bought links are the fastest way to get into trouble. Google's policies explicitly list buying or selling links for ranking, large-scale link exchanges and automatically created links as spam [7].

• "1000 links for 15 euros" packages.
• Networks of sites created only for links.
• Comments with your link under other people's articles and in forums.
• "I'll link to you, you link to me" with dozens of strangers.

If someone promises you DA 50 in a month, run. Real growth is slow and steady.

How long it takes

Links build up gradually, and Google finds and counts them over time. Expect an effect after a few months, not a week. More in how long SEO takes. Check your score now, write the number down and look again in three months.
