Introduction
In Search Engine Optimization (SEO), several metrics are used to estimate how well a webpage can rank on search engines. PA full form is Page Authority, which is one of the most popular SEO metrics used to measure the ranking strength of an individual webpage.
If you are learning SEO or running a blog or website, understanding PA full form (Page Authority) is very important for improving search visibility and overall performance.
This article explains PA full form, what Page Authority is, how Page Authority works, how PA full form is calculated, and how to improve PA full form (Page Authority) effectively for better SEO results.
What Is Page Authority?
Page Authority (PA) is an SEO metric developed by Moz that predicts how well a specific webpage is likely to rank on search engine result pages (SERPs).
Page Authority is scored on a scale from 1 to 100.
A higher PA score indicates a stronger ability to rank in search engines.

What Does Page Authority Measure?
Page Authority measures the ranking strength of an individual page, not the entire website.
It is based on multiple factors, including:
- Quality of backlinks
- Number of linking domains
- Link relevance
- Overall link profile strength
PA uses machine-learning models to estimate ranking potential.
Page Authority vs Domain Authority
Many people confuse Page Authority with Domain Authority. Here is a simple comparison:
| Factor | Page Authority (PA) | Domain Authority (DA) |
|---|---|---|
| Measures | Strength of a single page | Strength of entire domain |
| Scope | Page-level | Website-level |
| SEO Use | Page ranking prediction | Domain ranking prediction |
| Created by | Moz | Moz |
Both metrics are important, but PA is more useful when comparing individual blog posts or URLs.
How Is Page Authority Calculated?
Page Authority is calculated using multiple SEO signals, mainly related to links.
Some key elements include:
- Number of backlinks pointing to the page
- Authority of linking websites
- Internal linking structure
- Spam score of backlinks
Important note:
Google does NOT use Page Authority as a ranking factor.
It is a third-party metric used only for SEO analysis and comparison.
What Is a Good Page Authority Score?
There is no “perfect” PA score, because it is relative.
However, generally:
- PA 1–20 → New or weak page
- PA 21–40 → Average authority
- PA 41–60 → Strong page
- PA 61+ → Very high authority
Always compare PA scores between similar pages, not across unrelated websites.
Why Is Page Authority Important for SEO?
Page Authority is important because it helps you:
- Estimate ranking potential of a webpage
- Compare competitor pages
- Identify strong pages for backlinks
- Improve internal linking strategies
SEO professionals often use PA to decide which pages deserve optimization or backlinks.
