Domain Authority vs Page Authority – Key Differences Explained in 2025
If you’re working on SEO, you’ve probably come across the terms Domain Authority (DA) and Page Authority (PA). Understanding the difference between these two metrics is essential for improving your website’s ranking on search engines.
In this article, we’ll explain Domain Authority vs Page Authority, how they are calculated, and how to use them to boost your SEO in 2025.
What is Domain Authority (DA)?
Domain Authority (DA) is a metric developed by Moz that predicts how well a whole domain will rank in search engines. It’s scored on a scale of 1 to 100—the higher the score, the more authoritative your website is considered.
Key points about DA:
-
Measures the entire domain, including all subdomains
-
Influenced by backlinks, website age, content quality, and trustworthiness
-
Higher DA usually leads to better search engine rankings
-
Helpful to evaluate your site against competitors
💡 Think of Domain Authority as the overall reputation and trust of your website in Google’s eyes.
What is Page Authority (PA)?
Page Authority (PA) is also a metric from Moz that predicts how well a specific page will rank on search engines. Like DA, it’s scored from 1 to 100.
Key points about PA:
-
Measures the authority of a single page rather than the entire domain
-
Influenced by on-page SEO, backlinks to that page, content quality, and user engagement
-
Helps you identify which pages have the potential to rank higher
💡 Think of Page Authority as the strength of a particular page rather than the whole website.
Domain Authority vs Page Authority – Key Differences
| Feature | Domain Authority (DA) | Page Authority (PA) |
|---|---|---|
| Scope | Entire domain & subdomains | Single webpage |
| Purpose | Predict overall domain ranking | Predict page ranking |
| Influencing Factors | Backlinks, domain age, content, trust | Backlinks to page, on-page SEO, content quality |
| Score Range | 1–100 | 1–100 |

Why Both Metrics Matter
-
DA helps you understand your website’s overall authority in your niche.
-
PA helps you optimize individual pages for better search rankings.
-
Both metrics are relative, so comparing with competitors in your industry is important.
-
Focus on building high-quality backlinks, improving content, and enhancing SEO to improve both DA and PA.
