When it comes to ranking your web pages higher on search engines, most website owners focus on keywords, backlinks, and content. But there’s another crucial metric that tells you how powerful and trustworthy a specific page is — it’s called Page Authority (PA).
In this article, we’ll cover:
-
What Page Authority is
-
Why PA matters for SEO
-
How it’s different from Domain Authority
-
How to check Page Authority using the best tools
-
And how to improve it for better rankings
Let’s get started!
📌 What is Page Authority (PA)?
Page Authority (PA) is a metric developed by Moz that predicts how well a specific page on your website is likely to rank on search engine results pages (SERPs). It’s scored on a scale from 1 to 100 — the higher the score, the better the chances of ranking.
⚠️ Important: Page Authority is not used by Google for rankings. It's a third-party metric that helps you estimate page strength compared to others.
🔍 Why is Page Authority Important for SEO?
Page Authority gives you an SEO snapshot of any specific URL. Whether it’s your homepage, a blog post, or a landing page — PA tells you how well that individual page might perform in search results.
Here’s why it matters:
| Reason | Benefit |
|---|---|
| Spot your strongest pages | Focus SEO efforts on them |
| Identify low-performing content | Improve or update them |
| Compare with competitors | See who has more authority |
| Track link-building impact | Watch PA grow with better links |
So if you want your pages to rank high — especially for competitive keywords — knowing their PA is essential.
🧠 How is Page Authority Calculated?
Page Authority is based on dozens of factors, including:
-
Number of inbound links to the page
-
Quality of those links
-
MozRank (link popularity)
-
MozTrust (link trustworthiness)
-
Internal linking structure
-
Content relevancy and crawlability
Moz uses a machine learning algorithm to calculate PA, comparing millions of pages across the web to assign your score.
🆚 Page Authority vs Domain Authority: What’s the Difference?
| Metric | Measures | Applies To |
|---|---|---|
| Page Authority (PA) | Ranking power of a single page | Specific URLs like blog posts, landing pages |
| Domain Authority (DA) | Overall strength of the entire domain | The whole website (e.g., blognerds.com) |
👉 If you're optimizing a single blog post or product page, PA is more relevant. For your whole website's reputation, DA matters more.

Few or no backlinks

Weak internal links

Thin or duplicate content

Poor on-page SEO
But don’t worry — every page starts at 1. You can improve it with the right strategy.

✅ 1. Build Quality Backlinks to the Page
PA is heavily link-driven. Earn backlinks from:
-
Guest posts
-
Niche forums
-
Resource pages
-
Content sharing platforms
✅ 2. Optimize Internal Linking
Link to the page from:
-
Your homepage
-
High-traffic posts
-
Contextually relevant pages
This passes link juice and helps Google crawl the page better.
✅ 3. Write High-Quality, Valuable Content
Google prefers rich, helpful, well-structured content.
Include:
-
Original research
-
Infographics
-
FAQs
-
Related queries
✅ 4. Improve Page Speed and UX
A slow page can hurt crawlability and user engagement.
Use:
-
Caching
-
Lazy loading
-
Optimized images
-
Clean design
✅ 5. Update the Page Regularly
Search engines love fresh content. Update your page every few months to stay relevant and improve rankings.
🧪 Tips for Using PA Metrics Wisely
-
Don’t chase a perfect score — Aim for better than your competitors.
-
Compare PA with actual keyword rankings to measure performance.
-
PA is a predictive metric, not a guarantee.
-
Focus on user value first — SEO comes second.
📊 Real Example: PA in Action
Let’s say you write a blog post about “Best Android Apps in 2025.”
-
You publish it → PA starts at 1
-
You get 5 backlinks → PA grows to 18
-
More internal links + social shares → PA reaches 30+
Result? Your post ranks in Google’s top 10.
