Free Page Authority Checker — see the Moz PA score for any page
The Page Authority Checker lets you look up the Page Authority score for a single URL. Because Page Authority (PA) is a metric owned by Moz, this PA checker surfaces the Moz page authority value from a connected Moz integration and reports it exactly as Moz provides it. We never invent, adjust, or estimate the number: if no Moz provider is connected, the tool honestly shows “insufficient evidence” instead of a guessed page authority score. Enter a URL to see the PA Moz returns, then use it to benchmark that page against the competitors you are trying to outrank.
What is a page authority checker?
A page authority checker is a lookup tool for one specific metric: the Page Authority of an individual web page. Unlike an on-page audit that reads your HTML, a PA checker reports a third-party score that summarises how strong a page’s link profile is relative to other pages on the web. Our checker is deliberately provider-dependent — it does not calculate a score of its own. It asks a connected Moz integration for the Moz page authority figure and shows you that value, with the source clearly attributed, so you always know exactly where the number came from.
What is Page Authority (PA)?
Page Authority is a score developed by Moz that predicts how well a single page is likely to rank in search results. It runs on a 1–100 logarithmic scale, which is important to understand: because the scale is logarithmic, moving from 20 to 30 is far easier than moving from 70 to 80, and the gap between the highest scores is much harder to close. PA is calculated from Moz’s own model of a page’s backlink profile and related signals, and Moz periodically recalibrates that model, which can shift scores across the whole web even when a page has not changed.
PA is a comparative, predictive score
The most useful way to read a page authority score is as a relative, comparative estimate, not an absolute grade. A PA of 40 is neither “good” nor “bad” on its own — it only becomes meaningful when you line it up against the pages currently ranking for your target query. That is why we report the raw Moz value and avoid promising any specific number or outcome.
PA vs DA: page-level versus domain-level
PA vs DA is one of the most common questions in link analysis, and the distinction is simple. Page Authority (PA) estimates the ranking potential of a single page, while Domain Authority (DA) estimates the overall strength of an entire domain. Both are Moz metrics on the same 1–100 logarithmic scale, and both are surfaced the same honest way in our tools — read from Moz, never fabricated.
When to use each
Use PA when you want to judge one specific page — a blog post, a product page, or a landing page you are trying to rank. Use DA when you are sizing up a whole website. The two work together: a strong domain can lift the pages on it, but a well-linked individual page can outrank pages on stronger domains. To check the domain-level figure, use our Domain Authority Checker.
What influences Page Authority?
Because PA is Moz’s metric, only Moz defines exactly how it is computed — but the score is driven primarily by a page’s link profile. The factors that generally correlate with a higher page authority score include:
- External links to that page. The quantity, and especially the quality, of other websites linking directly to the URL is the biggest driver of PA.
- The authority of the linking pages. A few links from strong, relevant pages typically count for far more than many links from weak or unrelated ones.
- Internal links. How your own site links to the page — from the homepage, hub pages, and related content — helps distribute authority to it.
- Overall link quality and relevance. Editorially earned, topically relevant links matter; spammy or manipulative links can drag a profile down.
To see the individual links pointing at a page, pair this checker with our Backlink Checker and review the referring domains behind the score.
How to improve a page’s authority
You cannot “edit” a PA number directly — it reflects the underlying links Moz sees. To realistically improve page authority over time, focus on the inputs that build a genuine link profile:
Earn quality backlinks
Create content worth citing — original research, useful tools, thorough guides — and promote it so relevant sites link to that specific page. A handful of strong, topical links usually moves the needle more than a pile of low-value ones.
Strengthen internal linking
Link to the target page from your most authoritative existing pages using clear, descriptive anchor text. Good internal linking channels authority to the pages you most want to rank.
Keep the page genuinely useful
Pages that satisfy searchers tend to attract natural links over time. Maintain the content, keep it accurate, and make it the best answer for its topic so other creators want to reference it.
Remember that Moz recalculates its index periodically, so a Moz page authority value can move up or down for reasons unrelated to your page. Track the trend, not a single snapshot.
Page Authority is not a Google ranking factor
This is worth stating plainly: Page Authority is a third-party comparative estimate, not a Google ranking factor. Google does not use PA, does not publish it, and does not endorse it. PA is Moz’s prediction of ranking potential, useful for benchmarking one page against another, but it is not a signal inside Google’s algorithm. Treat a high or low PA as competitive context — never as proof of how Google will rank you.
Why we read PA from Moz and never fabricate it
Our platform is evidence-first: every value we show is traceable to a real source. Page Authority is Moz’s proprietary metric, so the only honest way to present it is to surface it from a connected Moz integration and attribute it to Moz. We do not compute a lookalike score, we do not approximate PA from other data, and we do not fill in a number when the provider is unavailable. In that case you will see “insufficient evidence” — a deliberate, honest result. That way the page authority figure you act on is always the real Moz value or nothing at all.
Page authority best-practices checklist
- Connect a Moz provider so the PA checker can surface a real score; without it, expect “insufficient evidence”.
- Read PA as a comparative estimate against ranking competitors, not an absolute grade.
- Remember the scale is 1–100 and logarithmic — high scores are exponentially harder to gain.
- Use PA for a single page and DA for a whole domain; understand the PA vs DA distinction.
- Grow authority through quality backlinks and smart internal links, not shortcuts.
- Never treat PA as a Google ranking factor — it is a Moz benchmark only.

Frequently asked questions
What is a page authority checker?
A page authority checker is a tool that surfaces the Page Authority (PA) score for a specific web page. Page Authority is a metric created by Moz, so our PA checker reads the score directly from a connected Moz integration and reports it exactly as Moz supplies it. If no Moz provider is connected, we show "insufficient evidence" rather than guessing — we never invent or estimate a page authority score.
What is a good page authority score?
Page Authority is scored on a 1–100 logarithmic scale, and because it is comparative there is no universal "good" number. A page is best judged against the competing pages that rank for the same query, not against an absolute threshold. Higher is generally better, but a score only means something relative to the pages you are competing with. We report the PA value Moz returns and do not promise or predict any particular score.
What is the difference between PA and DA?
PA vs DA comes down to scope. Page Authority (PA) predicts the ranking potential of a single page, while Domain Authority (DA) predicts the ranking strength of an entire domain. Both are Moz metrics on the same 1–100 scale, but PA is page-level and DA is domain-level. You can check the domain-level metric with our Domain Authority Checker.
Is Page Authority a Google ranking factor?
No. Page Authority is a third-party comparative estimate produced by Moz, not a metric Google uses or endorses. Google does not use PA in its ranking systems. PA is useful for benchmarking one page against competitors, but it should never be mistaken for a direct Google ranking signal.
Do you calculate the page authority score yourselves?
No. Page Authority is Moz's proprietary metric, and we surface it from a connected Moz integration exactly as provided. We do not compute, adjust, or estimate PA ourselves. When a Moz provider is unavailable, the tool reports "insufficient evidence" instead of showing a fabricated number.
