What is Domain Authority and Page Authority?
Domain Authority (DA) and Page Authority (PA) are search engine ranking scores developed by Moz. Both are measured on a scale from 1 to 100 — the higher the score, the stronger a website or page is likely to perform in Google search results. They are not used by Google directly, but they are a widely trusted way to estimate the SEO strength of a site compared with its competitors.
Domain Authority (DA)
Domain Authority predicts how well an entire website (the whole domain) can rank. It is based largely on the quantity and quality of backlinks pointing to the site. A higher DA usually means a more established, trusted domain.
Page Authority (PA)
Page Authority predicts the ranking strength of a single page rather than the whole site. Two pages on the same domain can have very different PA scores depending on their individual backlinks and content.

What is a good Domain Authority score?
There is no single "perfect" number — what counts as a good DA depends on your industry and your competitors. As a general guide:
1–20
New or small websites. Normal for sites that are just getting started.
21–40
Growing sites that have earned some quality backlinks.
41–60
Established, credible websites with solid authority.
61–80
Strong, authoritative domains that rank well in competitive niches.
81–100
Top global websites such as major brands and news platforms.
Because DA is a comparative score, the smartest approach is to check your competitors' DA with this tool and aim to match or beat the leaders in your niche.
How to increase your Domain Authority
Domain Authority grows over time as your overall SEO and backlink profile improve. Here are the most effective ways to raise your DA and PA:
- Earn high-quality backlinks from relevant, trusted websites — quality matters far more than quantity.
- Create link-worthy content such as guides, tools and original research that other sites naturally want to reference.
- Strengthen internal linking so authority flows smoothly between your important pages.
- Remove or disavow toxic backlinks from spammy domains that can drag your Spam Score up.
- Fix technical SEO — improve site speed, mobile usability, crawlability and structured data.
- Be consistent and patient — authority is earned steadily, so keep publishing and building links.

DA PA checker — frequently asked questions
What is a DA PA checker?
A DA PA checker is a free SEO tool that shows a website's Domain Authority and Page Authority scores. These metrics, created by Moz, estimate how strongly a site or page can rank in Google search results on a scale of 1 to 100.
Is this domain authority checker free?
Yes. Our domain authority checker is completely free to use. There is no signup, no credit card and no limit on how many times you can check a website's DA and PA.
What is a good domain authority score?
DA is relative to your niche. As a rough guide, 1–20 is typical for new sites, 41–60 indicates an established site, and 80+ is reserved for major global brands. The best benchmark is to compare your DA with your direct competitors.
What's the difference between DA and PA?
Domain Authority measures the ranking strength of your entire website, while Page Authority measures the strength of a single page. Different pages on the same domain can have very different PA scores.
How is Domain Authority calculated?
Moz calculates DA using machine learning based on factors like the number of linking root domains and the total quality of backlinks. Scores are logarithmic, so moving from 70 to 80 is much harder than moving from 20 to 30.
How often does Domain Authority update?
Moz refreshes its index and recalculates DA and PA periodically. Your score can rise or fall as your backlink profile changes and as the data behind the index is updated.
Does a higher DA mean better Google rankings?
Not directly — Google does not use DA. However, a higher DA usually reflects a stronger backlink profile, which does correlate with better ranking potential. Treat DA as a useful benchmark, not a guarantee.
