The Story: I consulted with a SaaS company with a domain authority of 55—they had strong backlinks and good content. Yet their most important page—a product comparison page—wasn’t ranking despite ranking #1 for years previously. The issue? Their DA was 55, but that specific page only had PA (page authority) of 22. They’d built domain-level authority but didn’t build links pointing to individual pages. Once we built direct links to that page, it hit page 1 within 3 months. The lesson? DA matters, but PA is what actually ranks individual pages.
What Is Page Authority?
Page Authority (PA) is a score—also developed by Moz—predicting how well a specific page will rank in search results. Like DA, it’s scaled from 1 to 100.
Here’s the critical distinction: DA measures your entire domain’s authority; PA measures a specific page’s ranking potential. A page with high PA can rank even on lower DA sites if it has earned its own authority.
Domain Authority (DA)
Overall domain strength
Affects ALL pages
Page Authority (PA)
Individual page strength
Specific to ONE page
DA vs. PA: What’s the Difference?
Understanding the difference is crucial for SEO strategy:
| Factor | Domain Authority | Page Authority |
|---|---|---|
| Scope | Entire domain | Single page |
| What it measures | Overall link equity | Page-specific links |
| Can change | Slower change | Faster change |
| Strategy impact | Brand building | Page optimization |
Here’s what this means practically: you can have a low-DA site but if individual pages earn their own backlinks, those pages can rank. I’ve seen PA 40 pages outrank DA 60 domain pages because the PA page earned more relevant backlinks.
How Page Authority Is Calculated
PA uses similar signals to DA but at the page level:
- Links to that specific page – Direct backlinks to the URL
- Linking root domains – Unique domains linking to this page
- Page-level MozRank – The link equity the page has earned
- Internal links – How the page is connected in your site structure
- Content quality signals – Relevance, freshness, comprehensiveness
When to Focus on PA vs. DA
Strategic focus depends on your situation:
Focus on DA When:
- Building a new site
- Ranking competitive generic terms
- Building overall brand authority
- Your DA is below 20
Focus on PA When:
- Specific pages aren’t ranking
- You have content gaps
- Building links to key landing pages
- Your DA is good but pages still struggle
How to Increase Page Authority
Here’s what actually moves PA:
1. Build Direct Backlinks to Specific Pages
This is the most direct way to increase PA:
- Guest post with page links in author bio
- Earn relevant resource page links
- Build internal links from pillar content
- Create linkable content assets specifically for the page
- Use digital PR to build links to priority pages
2. Optimize Internal Linking
Internal links pass authority within your site:
- Link to important pages from homepage and navigation
- Connect related content through content clusters
- Use descriptive anchor text for relevance signals
- Ensure no orphaned pages exist
- Update old pages to link to new content
3. Create Page-Specific Linkable Assets
- Original research and data specific to the topic
- Custom graphics and infographics
- Tools and calculators
- Comprehensive guides on the exact topic
- Resource lists and recommendations
4. Improve On-Page SEO
- Optimize title and meta description
- Use proper heading structure (H1, H2, H3)
- Add schema markup for rich snippets
- Include relevant keywords naturally
- Ensure great user experience
5. Update and Improve Content
Fresh content signals authority to both users and search engines:
- Update outdated information
- Add new data and statistics
- Expand with more comprehensive coverage
- Add new multimedia
- Improve readability
Pro Tips for PA Excellence
- Build direct links to priority pages – Don’t rely on home page links only
- Target linking domains – Relevant links matter more than volume
- Faster to improve than DA – Specific pages can gain PA quickly
- Monitor individual pages – Track PA for important URLs
- Cluster content – Pillar to cluster internal links pass PA
- Create hub pages – High-PA pages can boost lower-PA cluster pages
Common PA Mistakes
- Only building home page links – Individual pages need their own links
- Ignoring internal linking – Missed opportunity for authority
- Not tracking pages – PA varies by URL; you must measure specific pages
- Ignoring orphan pages – No internal links = no authority passed
- Neglecting content updates – Old content doesn’t earn links
- Same anchor text everywhere – Diversify anchor for natural link profile
Strategic PA Building
Here’s how to build PA strategically for your most important pages:
| Page Type | PA Strategy | Target PA |
|---|---|---|
| Homepage | Main link building focus | 40-60 |
| Pillar Pages | Hub content + links | 30-50 |
| Product Pages | Direct external links | 25-40 |
| Blog Posts | Content + community | 20-35 |
| Landing Pages | Paid + organic links | 25-45 |
Frequently Asked Questions
What’s a good PA to start with?
New pages start at PA 1-10. With good content and some promotion, 15-25 is achievable in 3-6 months.
Can a page rank with low PA?
Yes—but only for low-competition keywords. For competitive terms, PA 30+ is typically needed.
Does DA affect individual page PA?
Yes—higher DA provides more link equity to distribute. But direct external links can overcome lower domain authority.
How long does it take to increase PA?
Individual pages can increase PA in 1-3 months with consistent link building—faster than domain-level DA changes.
