Expert Tips

Use DA & PA Like a Pro SEO

🎯

DA for Prospecting, Not Ranking

DA and PA are Moz's third-party metrics, Google does not use them as ranking signals. Use them to qualify link-building prospects and compare domain strength, not to predict your own rankings. Your actual rankings depend on Google's own Quality scores.

🚨

Spam Score Matters

A low DA with a high Spam Score is a red flag, the domain may have low-quality or manipulative links. Avoid acquiring links from sites with Spam Scores above 30%. Always combine DA/PA data with a manual review of the site's content quality.

📈

Focus on Link Relevance

A DA 40 link from a highly relevant niche site is worth more than a DA 80 link from an unrelated domain. Google values topical relevance heavily. Use DA/PA as a baseline filter, then prioritise relevance and editorial quality above pure authority score.

About the Data

What Do These Metrics Mean?

Domain Authority (DA) is a 1 to 100 logarithmic score developed by Moz that predicts how well a domain will rank in search engines, based on its total backlink profile. Page Authority (PA) measures the same for a specific page rather than the whole domain. Spam Score flags sites that share characteristics with penalised or banned sites, scored 1 to 17 (low/medium/high). Referring Domains is the number of unique root domains linking to the site, and is one of the strongest indicators of real authority. Scores are modelled on Moz's methodology and are directional indicators, cross-reference with Ahrefs DR or Semrush AS for a fuller picture.

Moz recalculates DA roughly once a month when it recrawls the web and refreshes its link index, so some fluctuation between checks is normal. DA can drop even when you changed nothing, because it is a relative score. If Moz retrains its model or a competitor gains links faster than you, your number can slip on its own. Before you react, check whether your actual rankings and traffic moved or only the third-party score. A real drop almost always traces back to lost or broken backlinks. And because the score leans on link signals, it can be inflated with manipulative links, which is why a high DA on its own means little. Treat it as a comparison number, not a target, and let relevant quality links drive the work.

Free DA PA Checker

A Free Website DA PA Checker Built From Real SEO Work

This free DA PA checker tool measures the authority of any website in seconds. Paste one or more URLs and it returns the Domain Authority and Page Authority, both scored 0 to 100 by Moz, along with the spam score, so you can gauge a site's strength at a glance. Domain Authority reflects the whole website, Page Authority reflects a single page, and both are built mainly on the quality of the links pointing to them. There is no sign-up and no credit card, it is a free online domain authority checker.

DA and PA are useful, but only if you read them correctly. Over 17+ years running SEO across 500+ projects, I have watched people chase a bigger DA number as if it were the goal. It is not, it is a comparison tool. Use this website DA PA checker to size up a link prospect against others, to see how you stack up against competitors and to track whether your link building is moving the needle over time, not as a score to obsess over in isolation.

One thing worth being clear about, DA and PA are Moz metrics, not Google's, and Google does not use them to rank your site. Ahrefs has its own version called Domain Rating, and Google's original internal score was PageRank. They are all handy third-party estimates of authority, nothing more. The real way to raise them is the same thing that actually helps your rankings, earning relevant, quality backlinks from trusted sites and checking the spam score before you pursue a link. Check your DA and PA regularly, but let real link quality drive the decisions. Pair this with the free broken link checker to reclaim broken backlinks that are lost authority, or explore all the free SEO tools to strengthen your whole profile.

Two things are worth keeping straight. First, none of these numbers is a Google signal, John Mueller has said plainly that Google assigns no site-wide authority score, and Moz rebuilt Domain Authority in 2019 as a machine-learning model trained to predict Google results, so a high score tracks rankings because both are driven by the same strong backlinks, not because Google reads the score. Ahrefs calls its version Domain Rating and Semrush calls its own Authority Score, and the three rarely match because each uses different data and spam maths. Second, a good number is relative, a DA of 30 can be strong for a local trade site and weak for a national finance term, so read it against the sites you actually compete with and let topical depth, not the digit, guide the work.

DA PA Checker FAQ

Frequently Asked Questions

How do I check the DA and PA of a website?

Paste one or more URLs into this free DA PA checker and run it. In seconds it returns each site's Domain Authority and Page Authority score out of 100, plus the spam score. No sign-up or install is needed.

Is this DA PA checker tool really free?

Yes. This online domain authority checker is 100% free with no sign-up and no credit card. You can check your own website and any competitor or link prospect, as often as you like, completely free.

What is the difference between DA and PA?

Domain Authority scores the ranking strength of a whole website, while Page Authority scores a single page. Both are Moz metrics on a 0 to 100 scale and are based mainly on the quality of the links pointing to the domain or page.

Is Domain Authority a Google ranking factor?

No. Domain Authority and Page Authority are third-party scores from Moz, not metrics Google uses. They are useful for comparing sites and tracking your own trend, but Google does not rank by them.

What is a good DA or PA score?

Scores run from 1 to 100 on a logarithmic scale, so climbing from 20 to 30 is far easier than 60 to 70. Judge your score against direct competitors in your niche, not against giant sites.

How can I improve my DA and PA?

Earn links from relevant, trusted sites, publish content worth linking to and keep your own site technically clean. Check the spam score of any site before you pursue a link. Authority is a byproduct of doing the fundamentals well, not something you buy.
