Page Authority Checker

A Page Authority (PA) Checker is an SEO tool that measures the ranking potential of an individual page on a scale from 1 to 100, based on various link-related metrics. It helps assess how likely a specific page is to rank in search engine results.

The PA metric was developed by Moz, and while it’s not used by Google, it’s a widely accepted benchmark for evaluating page-level SEO strength.

✅ Quick Definition:
Page Authority (PA) = Predictive score of a single page's ability to rank, based on links, content, and relevance (Moz metric).

 

Why Page Authority Matters

📈 Key Reasons to Track PA:

• Identify strong/weak pages on your site
• Measure link-building progress at the page level
• Prioritize optimization efforts for underperforming content
• Benchmark landing pages against competitors
• Support internal linking strategies

💡 Real-World Insight:
We used PA scores to identify underperforming blog posts on a client site. After building links to those pages, organic traffic increased by 45% in 60 days.

 

How Page Authority Is Calculated

Moz calculates PA using a machine learning model that includes:

• Linking root domains to the page
• Quality of incoming backlinks
• Total number of links
• MozRank and MozTrust scores
• Spam score signals

📊 Key Difference:

Metric	Level
Domain Authority (DA)	Entire domain
Page Authority (PA)	Individual page

What’s a Good Page Authority Score?

PA Score	Meaning
1–20	Weak — new or low-link page
21–40	Moderate — some link equity
41–60	Strong — solid backlink profile
61–80	Very strong — authoritative
81–100	Elite — major brand or viral page

📌 Note: PA is logarithmic, so going from PA 20 → 30 is easier than 60 → 70.

 

Common Misconceptions About Page Authority

Frequently Asked Questions

Q: Can I compare PA across different domains?

A: Yes, but only at the page level. For domain-wide comparison, use Domain Authority instead.

Q: Can a page with low PA rank high?

A: Yes, especially if it matches search intent and is well-optimized. But PA often correlates with stronger rankings in competitive niches.

Q: How often should I check Page Authority?

A: Monthly is a good cadence to track progress — especially after link-building campaigns.
