Domain Authority (DA) is a search-engine ranking score that predicts how likely a website is to appear in search results. It was popularised by Moz, but the concept is used by every major SEO platform — Ahrefs calls it Domain Rating, SEMrush calls it Authority Score, and the open-source community uses Open PageRank, which is what powers the checker above.
DA is expressed on a logarithmic scale from 1 to 100. Higher is better. The scale is intentionally non-linear: moving from DA 20 to DA 30 is fairly easy; moving from DA 70 to DA 80 takes years of consistent link-building. That curve mirrors the real distribution of authority on the web — there are millions of low-authority domains and only a tiny number of household-name sites at the top.
DA is not a Google ranking factor. Google has its own internal authority signals and does not publish them. DA is an external estimate that correlates strongly with how a site actually performs, because it measures the same underlying signal: the quantity and quality of other sites that link to you.
Every authority score is built from a crawl of the public web. The crawler builds a graph of which sites link to which, then runs an algorithm — usually a variant of PageRank, sometimes with a machine-learning layer on top — to score every domain by how trusted the rest of the web treats it.
How many unique websites link to you. One link from 50 different domains is worth far more than 50 links from one domain.
A link from a high-authority site (a major news outlet, a respected publication) passes far more authority than a link from a brand-new blog.
Links from topically related, trustworthy sites count more. Links from spam farms or unrelated foreign sites can hurt or be ignored entirely.
Older domains with a steady link history score higher. A sudden spike of links looks suspicious; consistent growth looks earned.
Under the hood
Open PageRank — the data source used by this tool — assigns every domain a score from 0 to 10 by simulating Google's original PageRank algorithm across roughly 200 million crawled domains. We multiply that 0–10 figure by 10 to express it on the familiar 0–100 Domain Authority scale that most SEO professionals use as a mental model.
DA is best treated as a relative metric — compare yourself to your direct competitors, not to Wikipedia. That said, here are reasonable benchmarks:
| Score | Tier | Typical Profile |
|---|---|---|
| 1 – 20 | New / Low | Brand-new sites, personal projects, sites with very few inbound links. |
| 20 – 40 | Average | Small businesses and growing blogs. Ranks for long-tail keywords. |
| 40 – 60 | Strong | Established SaaS sites, niche-leading blogs, mid-size publishers. |
| 60 – 80 | Excellent | Major industry publications, well-known brands, large e-commerce. |
| 80 – 100 | Elite | Wikipedia, BBC, Google, Amazon — the top 0.01% of the web. |
DA moves slowly because it reflects something slow: the rest of the web's opinion of your site. There are no shortcuts, but there are reliable inputs.
The single biggest factor. Publish content other people actively want to link to — original research, definitive guides, useful free tools (this page is one). Pitch journalists. Guest-post on relevant industry sites. One link from a DA 70 site outranks a hundred from DA 10 directories.
Spammy backlinks — link farms, irrelevant foreign sites, paid link networks — can drag a score down. Use a backlink audit tool, then disavow what you can't get removed.
Link your own pages together with descriptive anchor text. This spreads authority across the site, helps crawlers, and boosts the pages that deserve to rank.
HTTPS, fast load times, clean URLs, an XML sitemap, a robots.txt, mobile-friendly layout. These don't move DA directly, but they keep the link equity you've earned from leaking out through broken pages and crawl errors.
Sites with no fresh content slowly drift down. Sites that publish useful material on a steady cadence attract organic links over years. DA rewards consistency, not bursts.
A new domain rarely breaks past DA 30 in its first year, no matter how aggressive the strategy. The score is a trailing indicator — what you do today shows up six to twelve months later.
No. DA is a third-party prediction, not something Google sees or uses. It correlates with rankings because it estimates the same underlying link-authority signals Google's algorithm rewards.
Every vendor runs its own crawler and its own algorithm. Moz Domain Authority, Ahrefs Domain Rating, SEMrush Authority Score and Open PageRank will all give different absolute numbers. The relative ordering between sites is usually consistent — pick one metric and stay with it.
Open PageRank refreshes its dataset on a rolling crawl, typically every few months. That's normal for authority metrics — the underlying link graph doesn't change daily, so frequent re-checks of the same domain will return identical scores until the next refresh.
Yes. DA measures the domain. Individual pages still need to match search intent, be technically crawlable, and outcompete other pages for a given query. High DA is a tailwind, not a guarantee.
Short-term: maybe. Long-term: it usually backfires. Algorithms detect unnatural link patterns; Google penalises bought links; and most sold links come from low-trust networks that drag a score down. Earn links by producing things people actually want to cite.
