What is Page Authority (PA)?

Alright, let’s cut through the SEO jargon for a second. What is Page Authority? It’s one of those metrics that gets tossed around a lot, but not everyone really understands what it’s measuring—or why it matters.

At its core, PA is about the strength of a single webpage. Think of it as the reputation of one employee in a giant company. Meanwhile, Domain Authority (DA) is like the reputation of the entire company itself. You might work for a company everyone trusts, but if you’re a slacker, your personal reputation doesn’t magically soar. That’s exactly how PA works: one page can be a superstar even on a relatively unknown site, and one weak page can drag down a strong site’s performance.

PA scores range from 1 to 100. Higher is obviously better, but don’t get obsessed. Google doesn’t use PA in its ranking algorithm—it’s a predictive metric created by Moz. That said, it’s still an incredibly useful tool for marketers, content creators, and business owners who want a gut check on how competitive their page really is. Treat it like a compass, not a magic number.

Let’s face it: if you’re in content marketing, you’re juggling a lot. You’re creating blogs, product pages, tutorials, videos, and maybe even interactive tools. PA gives you a quick snapshot of which pages are truly “winning” in the eyes of search engines, so you can decide where to focus your energy. Without a predictive metric like this, you’d be guessing blindly.

How Page Authority is Calculated

So, what is Page Authority really measuring under the hood? The answer: backlinks. PA is almost entirely backlink-driven. It doesn’t care much about flashy design, the number of words on the page, or even how much traffic you’re getting. It cares about who links to your page and how much weight those links carry.
Here’s a simplified breakdown of how Page Authority is calculated:

  1. Unique Linking Domains: The more unique websites linking to your page, the better. One link from a highly reputable site is stronger than 20 links from a low-quality blog. Don’t chase quantity over quality; diversity matters. A common mistake is obsessing over a single metric like “total links.” Remember: Google and Moz models care more about the diversity of sources than raw numbers.
  2. Authority of Linking Domains: Not all links are created equal. A link from The New York Times or Forbes is worth far more than a dozen from random sites nobody trusts. Think of it like a job recommendation: one recommendation from a top CEO carries more weight than 50 from people with no real reputation.
  3. Link Profiles of Linking Sites: It’s like “linkception.” If a site linking to you also links everywhere indiscriminately, that link is weaker. The algorithm looks at the quality of the sites linking to your page. In other words, it’s not just who’s linking to you, but who they are linking to that matters.
  4. A Complicated Algorithm: Moz’s model crunches all this data and produces a raw score. Don’t worry, the math isn’t for humans—it’s their secret sauce. But understanding that it’s a model of real-world link influence is key.
  5. The Logarithmic Scale: This raw score is converted to a 1–100 scale. It’s much easier to jump from 20 to 30 than from 70 to 80. That last stretch is where the heavy lifting happens—earning high-authority links from well-established domains. It’s a reflection of diminishing returns, just like in life: the higher you go, the harder it is to climb further.

PA isn’t a guarantee of ranking; it’s a prediction. It tells you if a page has the potential to compete, but you still need great content, a smooth user experience, and a strategy that earns trust. The worst thing you can do is fixate on the number alone. Focus on building substance, not vanity metrics.

PA vs. DA: Clearing Up the Confusion

A common question is: What is Page Authority compared to Domain Authority?

  • Domain Authority (DA): The overall reputation of a website. Think of it as the brand’s credibility.
  • Page Authority (PA): The reputation of an individual page.

Here’s why it matters: a page with high PA can outrank competitors even on a low-DA site. Conversely, a high-DA site can have pages with low PA if those pages haven’t earned strong backlinks.

This distinction is crucial for content strategy. For example, suppose you run a small startup blog. You publish a single in-depth article that goes viral. Suddenly, that page’s PA skyrockets, attracting more links and traffic—even though your overall DA is still modest. That’s the magic of focusing on individual page authority.

If you’re a content marketer, understanding this difference is essential. It tells you where to invest your efforts, which pages to boost internally, and which ones need external links. Don’t assume every page will automatically rank because your DA is high. Each page must earn its authority.

Why PA Still Matters

Even if Google doesn’t use PA directly, it’s still a critical tool. Think of it as an early-warning system for your SEO strategy. It gives insights into link-based trust and page credibility, which are factors Google does care about.

How PA Helps:

  • Competitive Analysis: Compare your pages to competitors. If your competitor has a PA of 60 and yours is 25, you know where to focus. This prevents wasted effort on guessing what works.
  • Prioritizing Work: Focus on strategic pages with low PA but high value. Don’t waste resources on pages that are already performing well.
  • Tracking Progress: Monitor if your efforts—like content promotion and link-building—are paying off over time. A PA that’s dropping is a red flag: links are disappearing, or competitors are out-earning you.

Pages with a higher PA tend to pull in more traffic, get more visibility, and generally just do better. But chasing PA without a holistic strategy is like running on a treadmill—you sweat, but you don’t really go anywhere.

The Unseen Power of Trust Signals

You might think, “Links, got it. I’m done.” Not quite. The game has gotten a lot more nuanced. Google now looks for trust signals, subtle signs that show real users are engaging with your content.

Think of it like a party. When someone tells a story, you don’t just listen—you watch reactions. Are people leaning in? Nodding? Sharing the story? Online, it’s the same:

  • Users scrolling all the way down your page signals engagement.
  • Clicking internal links shows they trust your content.
  • Social shares, mentions, and external recommendations are loud, clear signals of credibility.

Even if a page doesn’t have a massive backlink profile, strong engagement can nudge its perceived authority upward. PA models, like Moz’s, increasingly account for these nuanced behaviors.

In short: links matter, but trust signals matter too. A page can have 50 links but fail if people bounce immediately, while a page with 10 quality links and engaged readers will thrive.

How to Boost Your Page Authority

 

So, what is Page Authority good for if you want to take action? Simple: use it as a roadmap for growth.

  1. Create Link-Worthy Content:
  • Original research, surveys, or unique data.
  • Comprehensive guides and tutorials.
  • Visual assets like infographics, charts, and videos.
  • A bad outcome here is publishing content that’s useful but invisible—no one can find it, share it, or link to it.
  1. Earn High-Quality Backlinks:
  • Guest post on authoritative sites.
  • Digital PR: mentions in major publications or industry newsletters.
  • Broken link building: replace dead links with your content.
  1. Optimize Internal Linking:
  • Link from high-PA pages to pages you want to boost.
  • Keep a logical, clean site structure so authority flows naturally.
  1. Keep Content Fresh:

Update stats, examples, and insights regularly. Old content loses PA over time.

  1. Nail Technical SEO:

Fast-loading, mobile-friendly, secure pages. A technically broken page won’t matter how high its PA is.

  1. Track, Analyze, Adjust:
  • Monitor backlinks, competitor PA, and engagement metrics. SEO is ongoing; neglect kills authority.

Remember: consistency beats intensity. A page that earns a few links per month for years will usually outperform a page that earned 50 links in a single week and then stagnates.

 

Additional Considerations

 

  • Content Format: Long-form content often attracts more links, but visual and interactive content can earn even stronger PA.
  • Topic Authority: Pages in niche topics may earn links faster than general topics, but relevance is critical.
  • Competitor Context: Always consider PA relative to competitors. A PA of 40 may dominate in a small niche but struggle in a crowded vertical.

Wrapping Up

So, what is Page Authority really? It’s a predictive metric that acts as your SEO compass. It doesn’t guarantee rankings, but it gives you a clear signal of where your content stands in the competitive landscape.

Key takeaways:

  • PA is for pages, DA is for domains.
  • Links matter, but engagement and trust signals increasingly impact perceived authority.
  • Build content people love, earn high-quality backlinks, and optimize for usability.
  • Track your efforts over time; SEO is a marathon, not a sprint.

Ultimately, PA is a guide, not a goal. Use it wisely, and it will keep your SEO strategy grounded, focused, and effective.
