Domain Authority & Page Authority Checker – Free DA PA Tool

Two of the most important authority metrics in SEO – checked in one place, instantly. Whether you are evaluating a website as a whole or assessing the strength of a specific page, Domain Authority (DA) and Page Authority (PA) give you the clearest picture of where a site stands in the eyes of link equity.

Enter any URL below and get both your DA and PA scores in seconds. No account required. No credit card. Free to use, every time.

What Is Domain Authority (DA)?

Domain Authority (DA) is a search engine ranking score created by Moz. It measures the overall strength of a website’s backlink profile on a logarithmic scale from 1 to 100. The higher the DA, the more authoritative the domain and the stronger its predicted ability to rank across competitive search queries.

DA is calculated based on the number of unique referring domains pointing to your site and the quality of those linking domains. It is not a Google metric – Google does not use DA as a ranking signal. However, websites with high DA consistently perform well in organic search because a strong, diverse backlink profile is exactly what Google’s algorithm rewards.

Marketers use DA to:

Vet guest posting sites before outreach
Compare domain strength against direct competitors
Track the cumulative impact of link-building campaigns
Filter low-quality or spammy link partners during a backlink audit

What Is Page Authority (PA)?

Page Authority (PA) is also a Moz metric – but where DA measures an entire website, PA measures the ranking strength of a single specific page. It runs on the same 1–100 logarithmic scale and is calculated based on the backlinks pointing directly to that individual URL.

This distinction matters enormously in practice. A site can have a strong DA of 65 while hosting individual pages with PA scores as low as 5 – because those pages simply have not earned any direct inbound links yet. PA reveals the page-level truth that domain metrics alone cannot show.

SEOs use PA to:

Evaluate the link equity of a specific guest post placement URL
Identify internal linking opportunities between high-PA and low-PA pages
Prioritise which pages deserve focused link-building attention
Compare page-level strength across competitor content before targeting a keyword

Domain Authority vs Page Authority – What Is the Difference?

Both DA and PA are Moz metrics on a 1–100 scale, but they answer different questions:

Domain Authority (DA) = the SEO strength of the entire website
Page Authority (PA) = the SEO strength of one specific page on that website

A high DA does not automatically mean every page has high PA. The two are calculated independently. When making guest posting decisions, always check both – DA tells you about the site’s overall quality, PA tells you exactly how much link equity the specific placement page will deliver to your site.

What Is a Good Domain Authority Score?

DA is logarithmic – harder to move at higher levels. Always benchmark your DA against competitors ranking for your target keywords rather than chasing an absolute number.

DA ScoreAuthority LevelWhat It Means
1 – 20LowNew or minimally linked site. Limited ranking ability outside long-tail keywords.
21 – 40ModerateGrowing domain. Competitive in low-difficulty niches and local search.
41 – 60GoodWell-established site with strong link diversity and solid ranking capability.
61 – 80High AuthorityTrusted domain. Competes across competitive commercial and informational keywords.
81 – 100EliteMajor global publications – Wikipedia, Forbes, BBC, Amazon.

What Is a Good Page Authority Score?

PA has no universal benchmark – it depends entirely on your niche. Check the PA of pages already ranking on page one for your target keyword and use that range as your real target.

PA ScoreAuthority LevelWhat It Means
1 – 15LowNew or unlinked page. Minimal individual ranking potential.
16 – 30Below AverageEarly-stage page with few direct inbound links.
31 – 50Average–GoodSolid page authority. Competitive across low-to-mid difficulty topics.
51 – 70StrongWell-linked page. Competes comfortably for competitive search terms.
71 – 100Elite
Editorial powerhouses – Wikipedia articles, viral resources, major landing pages.

Why DA and PA Matter for Your SEO Strategy

They Filter Your Link-Building Targets

Before committing to any outreach campaign or guest post deal, checking DA and PA together tells you the full value of a placement. A high DA site can still host a low PA page – and the page PA is what actually determines how much link equity flows to your site. Always check both before you sign off on a placement.

They Set Your Competitive Benchmark

Check the DA and PA scores of every page currently ranking on page one for your target keyword. That range is your real authority benchmark. If competitors sit between DA 40–60 and PA 30–50, those are the numbers your content and backlinks need to match or exceed to break into that ranking cluster.

They Guide Your Internal Linking Strategy

Your highest-PA pages are link equity hubs within your own site. Pointing internal links from those high-PA pages toward lower-PA pages you want to rank passes link authority across your site without needing external backlinks. This is one of the fastest, most underused SEO tactics available.

They Track Your SEO Progress Over Time

Both DA and PA grow gradually as you earn quality backlinks. Monitoring them monthly gives you a clear, measurable way to track whether your link-building strategy is working – and to catch any backlink losses before they affect your organic rankings.

How to Check DA and PA – 3 Simple Steps

Using this tool is fast and straightforward. Here is what happens when you run a check:

Step 1 – Enter Any URL

Paste any domain or specific page URL into the input field. Check your own site, a competitor’s domain, or a potential guest post placement URL. For bulk analysis, enter multiple URLs at once to compare several sites side by side.

Step 2 – Run the Check

Click Check DA PA. The tool instantly pulls live data from Moz’s index and calculates both scores – DA for the domain as a whole and PA for the specific page URL you entered.

Step 3 – Read Your Results

Your results include DA score, PA score, total linking root domains, total inbound backlinks, and Spam Score – everything you need to make a confident link-building or guest posting decision.
