What is Page Authority PA? In Plain English

In Plain English

Page Authority (PA) is a score developed by Moz that predicts how likely a specific page on a website is to rank in search engine results.

It’s similar to Domain Authority (DA), but instead of measuring the whole website, it looks at just one page. The score ranges from 1 to 100 — the higher the score, the stronger that page is likely to be.

Think of PA like the popularity of a single book in a library. Domain Authority measures the whole library’s reputation, but Page Authority focuses only on one book.

How Page Authority is Calculated

Moz calculates PA based on factors such as:

• The number and quality of backlinks pointing to the page.
• The overall authority of the domain.
• The strength of internal linking within the website.

Like DA, PA is not a Google ranking factor, but it’s a useful way to compare pages.

Why PA Matters

• Content planning: Helps you see which of your pages are strongest.
• Link building: Identifies good pages to earn backlinks.
• Competitor analysis: Lets you compare your pages against others.

FAQs

Q: Is Page Authority the same as Domain Authority?
No. DA measures the strength of an entire domain, while PA measures the strength of a single page.

Q: What is a good PA score?
It depends on your competition. Higher scores (40+) usually suggest stronger pages, but it’s relative.

Q: How can I improve PA?
By building high-quality backlinks to that page, strengthening internal links, and creating valuable, shareable content.
