What is Domain Authority and Why Does It Matter?

Every site owner chasing better search rankings has heard of Domain Authority, but what does it really mean? Domain Authority, or DA for short, acts like a trust score for your entire website. Created by Moz, this score helps you see how likely your site is to rank well on search engines compared to others. For many, it’s a go-to metric when making quick decisions about SEO strategies, partnerships, and competition. The higher your DA, the more search engines trust your site, driving more visitors and giving your brand a stronger online presence.

The Origins and Purpose of Domain Authority

Moz introduced Domain Authority as a way to simplify how people measure their website’s strength in search. Before DA, there wasn’t an easy way to compare one site’s “ranking potential” against another’s. With so many ranking factors at play, Moz wanted to provide a single score that combined the most influential data for site owners, bloggers, and marketers.

  • Why Moz created DA:
    • To give websites a simple benchmark for tracking SEO progress.
    • To make it easier to compare your site with competitors.
    • To spot partnership and backlink opportunities quickly.

This has turned DA into a common SEO “currency.” It helps website owners measure, compare, and improve their visibility online. DA isn’t just for experts—it’s for anyone serious about growing their site. For a deep dive into the origins and purpose of Domain Authority, check out this resource from Moz DA (Domain Authority) Explained.

How Domain Authority is Calculated

Domain Authority isn’t just a random number. Moz calculates DA by running your site through an algorithm that checks dozens of different factors. Among the most important are:

  • Total backlinks: The number and quality of links pointing to your website matter a lot. More high-quality backlinks usually lead to a higher DA.
  • Linking root domains: Having many different sites link back is better than getting lots of links from a single site.
  • Site structure: Well-organized sites that are easy for search engines to crawl tend to have higher DA scores.
  • Spam score: Sites with spammy backlinks or poor link profiles can see their DA drop.

Moz updates DA regularly, so your score can change as your site and the web evolve. The score ranges from 1 to 100. Most small businesses start under 30, while top brands like Google can score near 100. For details on the calculation process, read Domain Authority: What is it and how is it calculated.

Domain Authority vs Page Authority: What’s the Difference?

Domain Authority and Page Authority (PA) sound similar but tell you different things.

  • Domain Authority (DA): Measures the overall trust and ability of your whole domain (your main site) to rank in search results.
  • Page Authority (PA): Looks at the strength of a single page on your site, predicting how well that specific page will rank.

When would you use each?

  • Use DA to see where your site stands overall and compare with competitors.
  • Use PA to identify which pages on your site are strong (or weak) and target improvements where it counts.

Focusing on both gives you a full picture. DA offers the “big view,” while PA zooms in page by page. This distinction helps shape smarter SEO strategies and boosts your odds of ranking for keywords that matter to your site.

Interpreting Your Domain Authority Score and Next Steps

You’ve checked your Domain Authority (DA), but now you’re thinking: is this number good, or is there room to grow? Knowing where your DA stands lets you make smarter choices for your website. But before you set goals or take action, take a closer look at what the score actually means, how to make it stronger, and what DA won’t tell you.

What is a Good Domain Authority Score?

A “good” Domain Authority score is all about context. DA scores run from 1 to 100, with higher numbers showing stronger ranking potential. But the same score can mean different things in different industries. Comparing your DA against huge brands might set you up for disappointment, while measuring against smaller, newer sites could give you a false sense of security.

  • New websites: It’s common to start with a DA under 20. This is not a sign of failure—just a starting line.
  • Local businesses or niche blogs: Scores between 20 and 40 are typical. In certain niches, a DA of 30 could make you one of the top contenders.
  • Popular brands and large content sites: These often range from 50 upwards.
  • Global authority sites (like YouTube or Wikipedia): These score in the 90s, but it’s not a realistic target for most.

It’s smarter to keep an eye on sites like your own. If your main competitors sit around 35, reaching 36 can push you ahead. There’s no single “right” score—what matters most is if your DA keeps moving in the right direction. For more details on DA ranges and how context matters, check out this explanation from Moz: Domain Authority - What is it and how is it calculated.

Improving Your Domain Authority: Actionable Strategies

If your DA isn’t where you want it to be, you’re not stuck. There are clear, practical steps to boost your score over time:

  • Build high-quality backlinks. Earning links from respected sites does more for your DA than a flood of low-quality links. Look for guest posting, news mentions, or partnerships with industry sites.
  • Create content people actually want to link to. Think original research, guides, or helpful tools. Content that solves real problems is far more likely to earn natural links.
  • Strengthen your internal linking. Make sure your pages connect in smart ways. This helps search engines crawl your site and spreads link authority where it’s needed.
  • Fix technical SEO problems. Broken links, slow load times, and poor mobile usability all make your site less attractive to both search engines and visitors.
  • Keep your site updated and active. Regular content updates signal your website is alive and trustworthy.

The Limitations of Domain Authority: What You Should Know

It’s easy to chase a higher DA score, but remember: DA is just a prediction, not a measure of actual traffic or rankings. Moz calculates DA using its own formula, pulled from factors like backlinks and site age. It’s a useful metric, but not the whole picture.

  • DA won’t tell you how much traffic you’ll get. A big jump in DA doesn’t guarantee higher search rankings for every keyword.
  • Every tool scores differently. Moz’s DA is not the same as Ahrefs’ Domain Rating or SEMrush’s Authority Score.
  • DA can be gamed or skewed by spammy tactics. Buying low-quality links might raise your score temporarily—but it rarely leads to real growth.

Focus on DA as a helpful benchmark, not the finish line. For more on what DA can—and can’t—show, you can review common pitfalls discussed in this article on things that damage DA and its limits.

Keep DA in your toolkit, but always look at other SEO signals, too. Ranking, traffic, and user engagement all matter just as much.
