SEO Moz Page Authority: What It Means and How to Improve It

SEO Moz Page Authority is a metric developed by Moz that predicts how likely a specific web page is to rank in search engine results pages (SERPs). Because it directly reflects the link-based strength of individual URLs, understanding this score is essential for any serious SEO strategy.

The score runs on a logarithmic scale from 1 to 100, meaning it becomes progressively harder to move from 60 to 70 than from 20 to 30. Therefore, even small gains at higher score ranges represent significant improvements in your page’s competitive standing.

What Does SEO Moz Page Authority Actually Measure?

SEO Moz Page Authority is calculated using a machine learning model that analyzes dozens of link-based signals. Specifically, Moz’s algorithm evaluates the number of unique root domains linking to a page, the authority of those linking pages, and the overall quality of the backlink profile.

However, it does not measure on-page content quality, keyword usage, or technical SEO factors directly. Instead, it focuses almost entirely on link equity — the collective value passed through inbound and internal links pointing to a given URL.

According to Wikipedia’s explanation of PageRank, the concept of assigning authority to pages based on inbound links dates back to Google’s original algorithm. Moz built Page Authority as a third-party approximation of this same underlying principle.

A Page Authority dashboard helps you compare the ranking strength of individual URLs across your site.

Page Authority vs. Domain Authority: Key Differences

Many SEO practitioners confuse Page Authority with Domain Authority, yet the two metrics serve distinct purposes. Page Authority evaluates a single URL, while Domain Authority measures the overall strength of an entire domain or subdomain.

For example, a high-authority website might have a Domain Authority of 75, but a specific blog post on that site could have a Page Authority of only 32 if few external links point directly to that URL. As a result, both metrics deserve attention in a well-rounded SEO audit.

In practice, use Page Authority when evaluating individual landing pages or blog posts you want to rank for specific keywords. Use Domain Authority when assessing the overall competitive strength of a website relative to its niche.

What Score Should You Be Aiming For?

A Page Authority score above 40 is generally considered competitive for most niches. Scores above 60 reflect pages with robust backlink profiles and strong topical relevance signals through their link context.

Because the scale is relative, however, the most useful benchmark is not an absolute number — it is your competitors’ scores. If your target keyword’s top-ranking pages average a Page Authority of 45, then reaching 50 gives you a meaningful advantage.

Five Proven Ways to Improve Your Score

Raising your Page Authority takes consistent effort across several link-building and site-structure disciplines. Below are the most effective approaches used by experienced SEO professionals.

1. Earn links from high-authority referring domains. A single backlink from a page with a PA of 70 carries far more weight than ten links from pages with PA scores below 20. Therefore, prioritize quality outreach over volume.
2. Publish link-worthy content formats. Original research, comprehensive guides, and data-driven infographics naturally attract editorial backlinks. Additionally, these formats generate social shares that can lead to further linking opportunities.
3. Optimize your internal linking structure. Strategically linking from your highest-PA pages to important target pages distributes link equity and can meaningfully raise those pages’ scores over time.
4. Reclaim lost or broken backlinks. Use Moz Link Explorer to identify links that once pointed to your page but are now broken. Reaching out to the linking site to restore those links is one of the fastest ways to recover lost authority.
5. Disavow toxic links. Low-quality or spammy links can drag your score down. Meanwhile, using Google’s Disavow Tool removes their negative influence and lets your legitimate links carry full weight.

A structured link-building strategy is the most reliable path to raising your Page Authority over time.

Common Mistakes That Hurt Your Ranking Potential

Many site owners inadvertently harm their Page Authority through avoidable errors. First, building large numbers of low-quality directory or forum links can dilute your profile rather than strengthen it. Although these links were once effective, Moz’s algorithm now weights them very lightly.

Another common mistake is neglecting internal links entirely. Pages that sit as isolated islands within your site receive little equity from your stronger pages, even if your overall domain has a healthy backlink profile. Consequently, a deliberate internal linking strategy is just as important as external outreach.

Finally, some SEOs treat Page Authority as a direct Google ranking signal and optimize for it in isolation. In contrast, the most effective approach treats it as one diagnostic indicator among many, used alongside keyword research, technical audits, and content quality assessments. Resources like RankAuthority can help you contextualize these metrics within a broader SEO framework.

How to Track Progress Without Getting Distracted

Because Moz updates Page Authority scores roughly once per month, checking your score daily creates unnecessary anxiety. Instead, schedule monthly audits using Moz Link Explorer or a platform that surfaces Page Authority data alongside organic traffic trends.

Track the Page Authority of your top five to ten most important pages and compare them against the average PA of pages currently ranking in the top three for your target keywords. This competitive gap analysis tells you exactly how much link-building work remains.

Additionally, correlate your PA trends with actual ranking changes in Google Search Console. If your PA rises but rankings stay flat, the issue likely lies in content relevance or technical SEO rather than link authority — and that distinction shapes your next move.

Tracking your Page Authority monthly alongside organic rankings reveals whether your link-building efforts are translating into real search visibility.

Putting It All Together

Understanding SEO Moz Page Authority gives you a measurable, actionable lens for evaluating and improving your pages’ competitive strength. By earning high-quality backlinks, refining your internal link architecture, and monitoring your score against competitors monthly, you can make steady, evidence-based progress.

Remember that Page Authority is a directional signal, not a guarantee. However, consistently improving it — alongside strong content and technical SEO — creates a compounding advantage that is very difficult for competitors to overcome quickly.
