When it comes to mastering SEO, one of the most critical metrics for measuring your website’s credibility is Page Authority (PA). Page Authority tells you how likely a specific page on your website is to rank in search engine results. It's a score developed by Moz, ranging from 1 to 100, with higher scores indicating better ranking potential. Whether you're a blogger, digital marketer, or small business owner, monitoring PA can help you make smarter SEO decisions—and that’s where a page authority checker comes in.

But with so many options out there, a common question arises: Should you go for a free tool or invest in a paid one? Let's break it down to help you decide what’s best for your SEO needs.

Understanding Page Authority: Why It Matters

Before diving into tools, it’s essential to understand why Page Authority is important. Unlike Domain Authority, which assesses the entire domain’s ranking potential, PA is laser-focused on individual pages. This distinction matters because a blog post, landing page, or service page might rank differently even within the same website.

Page Authority is influenced by several factors:

• Quality and quantity of inbound links

• The relevance of anchor text

• Link diversity

• MozRank and MozTrust metrics

Tracking PA regularly enables you to improve underperforming pages, build quality backlinks, and outrank competitors.

What Is a Page Authority Checker?

A page authority checker is a tool that evaluates the authority score of a specific URL. Most tools also provide associated data like Domain Authority, backlinks, spam score, and more. Depending on the tool you choose, these features can vary significantly in depth and accuracy.

These checkers come in two main types:

• Free tools: Basic features, limited searches per day, less in-depth metrics

• Paid tools: Advanced analytics, keyword tracking, competitor insights, API access, and much more

Free Page Authority Checkers: Pros and Cons

Let’s start with the free options. They’re great for beginners, occasional users, or small websites not looking to invest heavily just yet.

✅ Pros:

• Cost-effective: Obviously, the biggest benefit is that it’s free.

• Quick insights: You get immediate results for single or multiple URLs.

• User-friendly: Most tools are straightforward and require no sign-up.

❌ Cons:

• Limited features: Often just PA and DA scores without backlink profiles or traffic estimates.

• Restricted usage: Daily limits on the number of checks you can run.

• Lower accuracy: Some free tools pull data from outdated databases.

• No historical data: You can’t track progress over time.

Popular Free Tools:

• Moz Link Explorer (free version)

• Small SEO Tools

• Prepostseo DA PA Checker

• SEO Review Tools

These are handy for a quick overview but lack the analytical depth needed for serious SEO planning.

Paid Page Authority Checkers: Pros and Cons

If you're managing multiple websites, competing in a high-stakes niche, or offering SEO services to clients, investing in a paid tool can be a game-changer.

✅ Pros:

• Comprehensive metrics: Beyond PA/DA—get backlink breakdowns, anchor text usage, spam score, keyword rankings, and more.

• Bulk analysis: Upload hundreds of URLs at once for mass tracking.

• More accurate data: Access to live indexing and larger link databases.

• Tracking and reporting: Monitor changes over time and generate detailed reports.

• Customer support: Access to help desks, tutorials, and expert advice.

❌ Cons:

• Subscription costs: Ranges from $30/month to several hundred, depending on the tool and plan.

• Learning curve: Advanced features may overwhelm beginners.

Top Paid Tools:

• Moz Pro

• Ahrefs

• SEMrush

• Ubersuggest (offers both free and paid features)

These platforms offer far more than just PA checking, including keyword research, competitor analysis, and content suggestions—making them suitable for full-scale SEO campaigns.

Use Case Comparison: Free vs Paid

🎯 For Bloggers and Hobbyists:

A free tool might suffice if you're checking PA occasionally or tracking just a few URLs. You’ll get enough insight to guide basic SEO actions like backlink building or page updates.

💼 For Agencies and Marketers:

You’ll need a paid checker to manage multiple clients or complex SEO strategies. The ability to track PA over time, generate white-labeled reports, and conduct in-depth competitor research can provide a tangible ROI.

🛒 For E-Commerce and Business Sites:

If your revenue depends on search traffic, a paid tool will be crucial in identifying underperforming product pages, optimizing content, and capturing long-tail keywords.

Features to Look for in Any Page Authority Checker

Regardless of whether you choose a free or paid tool, look out for these must-have features:

• Real-time data updates

• Bulk URL input option

• Integration with Google Analytics or Search Console

• Historical tracking (for paid tools)

• User-friendly interface

• Export options for reporting

Conclusion

In the end, the decision between a free and paid page authority checker depends entirely on your goals, scale, and budget. If you're just starting out, a free DA PA checker will give you a good foundation. But as your SEO ambitions grow, so should your toolkit. Paid tools offer the insights and precision needed for sustained success, especially in competitive markets.
