What Is Page Authority (PA) and How to Read It

When a link seller says "the page has a high PA", it is tempting to hear "Google rates this page highly". That is not what the number says. Page authority is a score from a link-analysis tool, and it is one tool's estimate of how strong a single URL looks based on that tool's own data. Used with the right expectations, it still helps you decide which of your pages should receive a link first.

This article is about the page-level score only. It explains what page authority is, what it does not tell you, how to use it when choosing a target URL and which mistakes show up most often when people read it. At the end there is a reading table you can fill in for each candidate page, with fictional sample entries so you can see how it works.

What Page Authority Is and Who Calculates It

Page authority, usually shortened to PA, is a third-party metric that tries to estimate how likely an individual URL is to perform in search results, based mostly on the links pointing to it. The name is most closely associated with Moz, and other link-analysis products offer a comparable page-level score under different names. Each provider uses its own link index and its own calculation.

The key distinction is that PA is not a Google metric. Google does not publish a page score of this kind or say it uses one. A PA value therefore reflects a tool's reading of the link data it happens to have, not the weight Google places on the page. Details such as the exact scale, the formula and how often the score refreshes depend on the provider, and the dependable way to learn them is to read that provider's current documentation.

Why use it at all? Because it works as a quick comparative shortcut. If two candidate pages are measured in the same tool on the same day, their scores say something about how they stand relative to each other. It is a hint, and the decision still needs evidence about the page's topic, content and purpose.

Keep two habits from the start. Always note which tool produced a figure and when. And remember that a statement like "PA is 45" without a tool and a date is an incomplete piece of information, because the number only means something inside that tool's own world.

How to Read the PA Scale

Page-level scores are normally presented on a bounded numeric scale, and most tools design them so that higher values are harder to reach than lower ones. The exact structure differs by provider, so a rule that holds for one tool should not be transferred to another tool's score.

We deliberately give no threshold here such as "anything above this value is good". A cutoff like that flattens different industries, languages and levels of query competition into one line. A score that counts as strong in a small niche may be ordinary in a crowded market. The more useful question is not "is it high" but "where does it sit compared with the pages that already rank for my target query".

Three steps make the scale readable:

1. Stay in one tool. Setting scores from different tools side by side tells you nothing.
2. Define the comparison group. Look at the PA of the pages that appear on the first results page for the query you care about.
3. Read the gap, not the absolute value. The difference between your page and those competitors says more than any single number.

Remember too that a score moves over time. The same page can show different values across a month as the tool discovers new links and re-evaluates old ones. Recording the value together with its date makes later comparisons honest.

The Difference Between PA and DA

PA summarises one page, whereas DA aims to summarise an entire domain. The difference is simple but easy to blur. A site's homepage may have a strong link profile while a new blog post on the same site has received almost no links. In that case the domain-level metric is high and the page-level metric is low.

The domain-level pair, Domain Authority and Domain Rating, has its own comparison, which we wrote up in Domain Authority vs Domain Rating. If you are weighing whole sites against each other, start there. This article stays at the level of individual URLs.

The two kinds of score support different decisions. When you pick which site to publish on, the domain metric offers a rough view of the site's overall link standing. When you decide which exact page of yours should receive the link, or which page on the publisher's site will carry it, the page metric describes the neighbourhood the link will live in. A page buried deep in a strong site, with no internal links pointing to it, may not reflect the strength the domain score suggests.

Read them together but never swap one for the other. High DA with low PA can mean "we like this site but this page is weak". Low DA with high PA appears when a single page on a small site attracted many outside links. Either reading depends on the actual content of the page.

Factors That Influence a PA Score

How a score is calculated is provider-specific and outside the scope of this article, but the general direction is useful for interpretation. A page-level score tends to respond to how many links point at the page and how varied they are, how strong the linking pages themselves are and where the page sits within its own site. These are tendencies, not a recipe.

The idea behind this is that link value can pass from page to page, which we explain in link equity explained: how PageRank flows. It is the mechanism that page-level scores try to approximate in a rough way: links from strong pages are assumed to count for more than links from weak ones.

• External links: the number and quality of distinct domains linking directly to the page.
• Strength of linking pages: how well-linked the sources are in their own right.
• Position within the site: how many internal links the page receives and how close it is to the homepage.
• Age and exposure: new pages usually start low because they have had little time to collect links.

What is missing from this list also teaches something. The quality of the page's writing, its usefulness to a reader and how well it matches search intent are not parts of the score in any direct sense. A PA value does not measure whether a page is a good answer. A weak page propped up by strong links can score high, and an excellent but brand-new page can score low.

Using PA When You Choose a Target URL

Deciding which of your pages should receive a backlink influences how much value the campaign delivers. PA can act as one filter in that choice, but it should not be the only filter. We built a planning approach for spreading links across a package in backlink target URL distribution across a package; here we focus on the part PA plays inside such a plan.

Ask these questions in order. First, what is the purpose of the target page: does it answer a query, sell a product or introduce your brand? Second, where does the page stand now: for which queries and in what positions? Third, what is its PA relative to the pages that outrank it? Fourth, is the page ready to benefit from a link, meaning it loads reliably, is up to date and moves a visitor to a next step?

Consider a fictional scenario. An online shop has three category pages with clearly different PA values in the same tool. The page with the lowest PA could gain the most, but if its copy is thin and many products are out of stock, fixing it comes first. The mid-level page may sit close to the rivals on the first results page, so a small amount of link support could matter more there. The scenario shows a decision method, not a promised result.

The simple rule is to use PA to generate questions, not to rank your pages mechanically. A high-PA page has already attracted links. A low-PA page may be an opportunity, provided its content is ready. In both cases the decision rests on the page's goal and quality.

Mixing Up PA and PageRank

People often treat page-level scores and PageRank as the same thing. PageRank is a historical Google algorithm that uses links to estimate the importance of pages, and it now operates inside Google alongside many other signals. PA is an estimate produced by an outside tool from its own data. The similar names create an impression of equivalence that does not exist.

The practical consequence is that a high PA does not mean a page will automatically rank well on Google. At most it shows an approximation of link-driven strength. Search performance also depends on intent match, content, technical health and competition.

The way link value spreads within a site is often forgotten too. A page's strength comes not only from outside links but also from how the rest of the site links to it. A strong page can support others through internal links, a topic we cover in internal linking strategy and its SEO impact. A page that cannot attract many outside links can still gain importance through a deliberate internal structure.

In short, one is a tool's interpretation and the other is a historical concept tied to Google's own mechanisms. Use the first to take directional readings and the second to understand how links carry value. Do not equate them.

Expectations and Limits of Raising PA

"How to increase page authority" is a popular search, but PA is more usefully seen as an outcome indicator, not a target. Efforts to push the number directly tend to be artificial and fragile. It is more sensible to work on the factors behind it: the page should offer genuinely useful content, be able to attract links naturally and be supported from within the site.

Keep a few limits in mind. The score depends on tool data, and a tool needs time to find new links. A new page starting low is normal. Adding links does not by itself mean the score will rise, since quality, variety and relevance count. And a higher score does not mean a higher ranking.

We discuss the same kind of expectation management at domain level in how to increase Domain Authority. The logic carries over to pages: strengthen the causes rather than chase the figure.

• Create content that deserves to be linked and is genuinely useful to a reader.
• Support key pages from within the site with meaningful contextual sentences.
• Earn external links from relevant sources and related pages.
• Watch the score over weeks and months instead of judging from one reading.

Be wary of any offer that promises a result or a timeline. Nobody can say for certain when or how far a link will move a score.

Why Tools Score the Same Page Differently

Looking up one URL in two tools and seeing two different values is normal. Each tool crawls its own sample of the web, filters what it finds in its own way and applies its own formula. Refresh times also differ between products.

Three consequences follow. Comparing a PA from one tool with a PA from another is meaningless, because each score belongs to its own tool's universe. If you change tools, you must also change your comparison baseline. And if a seller quotes a flattering value from a tool of their choice, checking the same page in another tool is a fair test.

As a method, measure every candidate page in the same tool and note the date. Where possible, run a second tool as a sanity check on direction, for instance which candidate looks stronger. If both tools order the pages the same way, you have a firmer basis for the decision. Do not expect the numbers to match exactly.

What matters is to ask which tool and which date lie behind any PA figure you are given. "The PA is high" is not data. It is a claim, and like any claim it needs a source.

Where PA Fits When You Buy Backlinks or Sponsored Posts

In a purchase decision PA belongs near the end of the list, not the start. First look at the real nature of the site and the placement, and only then at numeric hints. The order below is a practical flow, and a deeper set of criteria is in how to spot a quality backlink.

1. Topical fit: does the publication and page relate to the subject of your content?
2. Real readers: does the site have an actual audience in the language you target?
3. Placement context: is the link given in a meaningful sentence with the right attribute?
4. Domain view: does the overall link profile look reasonable?
5. Page view: what are the PA and internal position of the page that will carry your link?

PA comes last because it only makes sense once the earlier steps have passed. A high PA on an off-topic page is a link that will not help you. A high PA on a page with no real readers is a warning, not a comfort.

Also remember that different pages on the same domain carry different PA values. If a publisher cites "our site's strong metrics", ask for the exact URL where your link will sit. A newly published article may start with a low PA, which is not a bad sign in itself. The position of the article and the quality of the links around it are what count.

The Most Common PA Interpretation Mistakes

Interpretation mistakes fall into a handful of repeating patterns. Knowing them gives you a short audit list for your own decisions. When reviewing them, it also helps to think about why variety matters, which we discuss in backlink profile diversification, because fixation on one metric makes variety easy to neglect.

• Treating PA as a Google score: it is a third-party estimate.
• Hunting for a threshold: saying "above this value is good" ignores context.
• Mixing tools: comparing one tool's score with another's.
• Trusting a single number: skipping topic, content and reader fit to look only at the score.
• Confusing domain and page: assuming high DA means high PA.
• Forgetting time: treating an old screenshot as current.
• Making the score the goal: chasing the figure rather than strengthening what lies behind it.

Most of these come from treating the number as an answer. PA is better handled as a question: why does this page sit where it does, and what could I add to it? Ask that and the figure helps. Treat it as the final answer and it will mislead you.

Sample Template: Page Level PA Reading Table

The table below is a reading sheet to complete for each candidate target page. The values are a fictional example and describe no real site; score figures are left out on purpose because scales differ between tools. Imagine you are comparing four pages of an online shop.

As you fill the sheet in, add the tool name and measurement date to each row, and replace the verbal positions with the real values from your own tool. In none of the rows does PA decide alone; the condition of the page and the gap to competitors form the real basis of the decision.

Frequently Asked Questions

Is page authority a Google ranking factor?

No. PA is an estimated score calculated by a third-party tool provider, and Google has not published it as a signal. Rankings depend on far more than links. PA only tries to approximate link-driven strength, so treat it as a hint and not as a Google measurement.

What is a good PA score?

There is no universal threshold. A good value depends on your tool, your industry and the pages that rank for your target query. A better approach is to use the same tool to compare your page with first-page competitors and to interpret the gap between them.

Are PA and DA the same thing?

No. PA summarises one page and DA summarises a whole domain. A strong domain can contain a new page with low PA. Treating them as interchangeable is misleading, especially when you are choosing which page should receive a link.

Why is the PA of a new page low?

A new page has had little time to collect links, and tools need time to discover new ones. This is normal and does not mean the content is poor. Supporting the page with internal links and letting it attract links naturally is a sensible path.

What can you do to raise PA?

Instead of targeting the score, strengthen what influences it: useful content, natural links from relevant sources and a solid internal link structure. Nobody can say beforehand when or by how much the score will change, so be sceptical of offers that promise it.

When buying backlinks, does PA or DA matter more?

Both belong behind topical fit, real readers and placement quality. After those checks, a domain-level score gives a view of the site and a page-level score gives a view of the specific page, and each is one extra hint rather than a deciding factor.

Conclusion and Next Step

Page authority estimates the link strength of one page. It is useful and limited at once: it is not a Google value, it depends on the tool and the date, and it never decides anything alone. Its most useful roles are comparing your page with ranking competitors, filtering candidate target URLs and prompting the right questions to a seller.

Three actions fit into this week. Measure your candidate pages in a single tool and record the date, complete the reading table above and give pages with a low PA but strong content internal support first. Then distribute your link plan according to that table, with the less crowded pages treated carefully.

When your plan is ready to become an order, the backlink packages page shows the options, and you can add a package to the cart and complete payment. After that the seller confirms the order and a delivery notice follows, and if what arrives differs from what you ordered, an objection route is built into the order flow.
