If you have ever checked your website’s SEO health, you have probably seen two scary scores: PA and DA. They sound similar, but they measure very different things. So in the comparison of page authority vs domain authority, which one should you actually focus on?
Both metrics predict how well your site can rank on Google. Yet, they work at completely different levels — one tracks a single page, the other tracks your entire domain.
This beginner guide breaks both scores down in plain English, then shows you exactly how to boost them in 2026.
What Is Page Authority?
Page Authority (PA) is a Moz-developed score that predicts how well a single web page can rank in search results. It uses a 1 to 100 logarithmic scale.
Higher PA means stronger ranking potential for that specific URL. So one page on your site could have very high PA while another has low PA.
What Is Domain Authority?
Domain Authority (DA) measures the strength of your entire website. It is also a Moz score using the same 1–100 scale.
High DA means your domain is trusted, well-linked, and likely to rank well overall. So DA reflects long-term SEO power, not single-page success.
Page Authority vs Domain Authority: Quick Comparison
| Feature | Page Authority (PA) | Domain Authority (DA) |
|---|---|---|
| Measures | One single URL | Whole website |
| Scale | 1 to 100 | 1 to 100 |
| Updated | Frequently | Less frequently |
| Best For | Page-level ranking | Overall SEO strength |
| Influenced By | Page backlinks & on-page SEO | Domain-wide backlinks |
In short, PA is page-specific, while DA is site-wide.
How Are Both Scores Calculated?
Moz uses dozens of signals to calculate both PA and DA. The most important ones include:
- Total number of inbound backlinks
- Quality and authority of those backlinks
- Linking root domains (LRDs)
- Anchor text relevance
- Spam signals and toxic links
Therefore, both scores reward genuine, high-quality link building.
Are PA and DA Google Ranking Factors?
No. Google does not use PA or DA directly. These are third-party metrics built by Moz to predict ranking strength.
However, since both correlate strongly with backlinks and trust, they are reliable indicators of SEO performance. Marketers use them daily for competitor analysis and SEO planning.

PA vs DA: Which One Matters More?
Both matter, but for different reasons. PA helps you rank specific pages. DA helps your brand build long-term SEO power.
So, treat them as a team — strong DA boosts every page, while strong PA delivers immediate ranking wins.
Common Myths About PA and DA
Myth 1: Higher DA Means Automatic Rankings
Not true. High DA helps, but every page still needs solid on-page SEO.
Myth 2: PA Updates Daily
Wrong. Moz refreshes data periodically, so changes appear gradually.
Myth 3: PA and DA Are Official Google Metrics
False. Both scores belong to Moz, not Google. Use them as estimates, not rankings.
How to Use PA and DA for Competitor Research
Smart marketers use both metrics together. Check competitors’ DA to see how strong their brand is, and PA to see which pages dominate.
Then build similar but better content. Reverse-engineer their wins using our Competitor Backlinks Checker tool.

FAQs
Page authority measures the ranking strength of a single page, while domain authority measures the whole website’s SEO power.
It depends. For ranking a single URL, PA matters more. For brand-level SEO, DA is the priority.
No. Both are Moz metrics. Google does not use them directly, but they predict SEO performance well.
A PA of 30+ is decent, 50+ is strong, and 70+ usually competes with major brands.
Improve internal linking, refresh content, and earn 3–5 quality backlinks to that specific page.
DA can drop after Moz index updates, lost backlinks, or new spam signals. It usually recovers naturally.
Once a month is enough. Daily changes are normal but rarely meaningful for long-term SEO.
