<\/a><\/p>\nTurns out, Page Authority is more of a compass than a finish line. In this post, I\u2018m breaking down what it actually is, how it\u2019s calculated, what a good score looks like, and what you can do to improve it \u2014 so you can use it to guide your strategy, not just grade it.<\/p>\n
Table of Contents<\/strong><\/p>\n <\/a> <\/p>\n Page Authority (PA) is a third-party metric created by Moz<\/a> that estimates the relative ranking potential of a specific webpage on a 0-100 scale. A higher score suggests the page is more likely to rank competitively in search engine results pages (SERPs).<\/p>\n Source<\/em><\/a><\/p>\n PA is scored on a 0-100 logarithmic scale, which means improvements become progressively harder to achieve the higher the score climbs. Moving a page from a PA of 20 to 30 takes far less effort than moving it from 70 to 80.<\/p>\n Moz calculates Page Authority using a machine learning model trained on thousands of search result data points. The primary input is the quality and quantity of inbound links pointing to a given page. Other signals, including linking root domains and MozRank, also factor in.<\/p>\n Pro Tip: <\/strong>Because PA is logarithmic, focus your energy on winning relevant backlinks rather than obsessing over moving the score a few points. The links drive the movement, not the other way around.<\/p>\n One important clarification: PA measures a single page, not an entire website. If you want a domain-level signal, that is what Domain Authority (DA) is for. I’ll cover the distinction in detail in the comparison section below.<\/p>\n <\/a> <\/p>\n No. Page Authority is not a Google ranking factor. Google doesn\u2018t publish a Page Authority score, and it doesn\u2019t use Moz’s PA metric in its algorithm.<\/p>\n Google has its own internal PageRank algorithm<\/a>, which is historically associated with link analysis. PageRank is a different system entirely, and Google stopped publishing public PageRank scores in 2016. The name similarity between \u201cPageRank\u201d and \u201cPage Authority\u201d causes ongoing confusion in the industry, but they are unrelated.<\/p>\n So why does Page Authority still matter? Because it correlates with rankings. Pages with strong PA scores tend to have strong backlink profiles \u2014 something Google does care about. PA is a proxy, not a cause. When a page has a high PA score, it typically signals that the page has earned credible links, which is a signal Google respects.<\/p>\n What We Like: <\/strong>Using PA as a comparative benchmarking tool rather than an absolute target. If your competitor\u2018s ranking page has a PA of 55 and yours is 30, that gap tells you something actionable about your link-building opportunity. It\u2019s the delta that matters, not the raw number.<\/p>\n My experience has taught me that the most dangerous thing a team can do is set a PA target as a KPI. When PA becomes a goal rather than a diagnostic, teams start chasing score improvements through shortcuts, like acquiring low-quality links, that can harm long-term performance. Treat PA as context, not a scoreboard.<\/p>\n <\/a> <\/p>\n These three terms are frequently conflated. Here is a clear breakdown of each, when to use them, and what distinguishes them.<\/p>\n Page Authority (PA): <\/strong>Created by Moz. Estimates the ranking potential of a specific page. Scored 0-100. Updated regularly based on Moz’s link index.<\/p>\n Domain Authority (DA): <\/strong>Also created by Moz. Measures the relative strength of an entire domain rather than a single page. A site’s DA score is influenced by the combined link equity across all of its pages. Learn more about Domain Authority here<\/a>.<\/p>\n PageRank: <\/strong>A Google algorithm historically associated with link analysis. Google uses PageRank internally, but it has not published public PageRank scores since 2016. PageRank is not a tool for practitioners to use; it is an internal Google signal.<\/p>\n Here is a side-by-side comparison to make the distinctions clearer:<\/p>\n When to use page vs domain metrics:<\/strong><\/p>\n Pro Tip: <\/strong>When evaluating link-building targets, check both PA and DA. A page with low PA on a high-DA domain is often a great acquisition target because the domain has strong equity but the specific page has room to grow.<\/p>\n <\/a> <\/p>\n There is no universal answer, because Page Authority is a relative metric. A PA of 40 might be excellent for a niche B2B service page and completely insufficient for a highly competitive keyword in the finance or health space. Context determines what counts as a good score.<\/p>\n That said, here is a general reference guide for interpreting PA scores:<\/p>\n I have seen pages with PA scores in the 20s outrank pages with PA scores in the 50s because the lower-authority page was a significantly better match for search intent. This is why PA is a signal, not a guarantee. A well-targeted, technically sound page with strong on-page optimization can punch above its PA weight.<\/p>\n The most important benchmark is competitive, not absolute. Use tools like Moz’s Link Explorer, Ahrefs, or Semrush to analyze the PA scores of pages currently ranking in the top three for your target keyword. That range becomes your practical target. You can also use HubSpot’s Website AEO Grader<\/a> to assess your overall site performance and surface gaps that could be affecting your pages’ authority.<\/p>\n <\/a> <\/p>\n Checking Page Authority doesn’t require any single tool. The goal is to assess ranking potential and link profile strength at the page level, and several platforms offer this data. Here is a tool-agnostic process:<\/p>\n For ongoing SEO performance tracking, HubSpot’s Marketing Hub SEO tools<\/a> let you monitor on-page optimization, keyword rankings, and content performance in one place, giving you the context to pair PA data with real ranking outcomes.<\/p>\n Best For: <\/strong>Teams doing competitive content analysis should build a simple tracking spreadsheet that logs the PA, DA, and linking root domains of the top three ranking pages for every target keyword. Run this audit quarterly to identify which content gaps have grown and which pages are gaining ground.<\/p>\n <\/a> <\/p>\n Chasing shortcuts is the fastest way to undermine a page\u2018s long-term authority. Buying links, joining link schemes, or overloading pages with exact-match anchor text might bump your PA in the short term, but they\u2019re also the kind of tactics that tend to attract algorithmic flags or manual penalties. Here is what actually works, based on SEO best practices<\/a> and durable signal improvement:<\/p>\n PA is primarily a link-based metric. The single most effective way to increase it’s to earn links from pages and domains that are themselves authoritative and topically relevant to your content.<\/p>\n Tactics that work include original research (data studies, surveys, proprietary reports), creating genuinely useful reference content, building tools or calculators your industry will cite, and proactive outreach to sites that link to similar content from competitors.<\/p>\n What We Like: <\/strong>Original data that makes your page a primary source. When a piece of content becomes the reference that others cite, the links compound over time without additional outreach effort.<\/p>\n Internal links distribute link equity across your site. A page buried without internal links receives none of the authority flowing through your higher-PA pages. Conduct a review of your ranking metrics<\/a> alongside a crawl of your internal link structure to identify pages that deserve links but are not receiving them.<\/p>\n The ideal internal linking strategy connects your highest-equity pages to the pages you most want to rank. If your homepage or cornerstone content has strong PA, make sure it links to your target pages with descriptive, keyword-relevant anchor text.<\/p>\n Pro Tip: <\/strong>Run a site crawl using tools like Screaming Frog<\/a> or Ahrefs<\/a> and filter for pages with strong organic traffic but few internal links pointing to them. These are your quick wins for internal link equity transfer.<\/p>\n A page that earns clicks, reads, and return visits signals quality to Google even if its PA is modest. Content that genuinely matches what searchers want tends to attract more organic links over time, which then drives PA upward.<\/p>\n Before optimizing for authority, confirm the page is doing the basic job: satisfying the query. A page with excellent intent alignment and a PA of 35 will often outperform a page with mediocre relevance and a PA of 55.<\/p>\n Page Authority cannot do its job if the page has technical problems. Crawl errors, slow page speed, broken links, and poor mobile performance all suppress a page’s ability to rank, regardless of its PA score. Audit pages for technical issues before investing in link building.<\/p>\n Refreshing content signals freshness and often earns new links as updated statistics or insights get cited. I’ve discovered that some of the fastest PA gains come not from new pages, but from significantly upgrading existing pages that already have some link equity. Adding new data, deeper analysis, or better multimedia can prompt existing linkers to update their references and new linkers to discover the page.<\/p>\n Pages rarely rank in isolation. A single page on \u201cemail marketing\u201d will rank more effectively if it’s part of a cluster of related, well-interlinked content on email marketing broadly. Building a content cluster around a core topic distributes authority from supporting pages to the pillar page and signals to Google that your site has deep expertise in the area.<\/p>\n Best For: <\/strong>Content Hub by HubSpot is built for this approach, enabling teams to create interconnected content clusters with clear pillar pages, topic coverage, and internal linking at scale.<\/p>\n Ten links from ten different relevant domains are more valuable to PA than ten links from the same domain. Moz’s model rewards linking root domain diversity. When building links, prioritize reaching new domains over accumulating additional links from sites that already link to you.<\/p>\n <\/a> <\/p>\n Monthly tracking is a reasonable cadence for most teams. PA fluctuates as Moz refreshes its link index, which happens regularly. Checking daily or weekly creates noise and can lead to reactive decisions based on index crawl variations rather than actual link profile changes. For competitive tracking, a quarterly deep-dive audit is usually sufficient.<\/p>\n Internal linking can help page authority, but not directly. When you link from one page to another, some link equity transfers to the linked page, which can raise its PA slightly. With that said, external backlinks are what actually drive PA in a meaningful way. Internal linking helps you get more out of the authority your site has already earned \u2014 it doesn’t create new authority on its own.<\/p>\n Yes, frequently. PA is one signal among many. Pages with low PA regularly outrank higher-PA pages when they are a better match for search intent, have stronger on-page optimization, or face low competition. In niche topics with few authoritative pages, a PA of 15 or 20 can be more than sufficient to rank on page one.<\/p>\n Comparing PA across industries is not particularly useful. A PA of 50 in the technology space may be competitive, while the same score would be below average in the news or finance sectors where major publishers dominate. Always benchmark PA within the actual SERP you are trying to compete in, not against some abstract industry average.<\/p>\n New pages start with a PA near 1 because they have not yet earned any backlinks, and PA is primarily a link-based metric. This is expected and normal. A new page won’t improve its PA through on-page optimization alone. Earning the first few relevant backlinks, building internal links from established pages, and giving the page time to be indexed and crawled will all contribute to gradual PA growth over weeks and months.<\/p>\n\n
