Domain Authority & Page Authority Checker – Free DA PA Tool
Find publishers for your campaign
Compare publisher opportunities by niche, audience, and placement price in the Posticy marketplace.
Compare the reported DA, PA, and Spam Score for domains while researching competitors and potential publishers. Use the results as a starting point for further checks.
Enter one domain per line in the field above. Checks are free within the daily allowance shown by the tool. Page URLs are reduced to their domain, so this checker does not provide the PA of a specific article.
What Is Domain Authority (DA)?
Domain Authority (DA) is Moz’s comparative score for a domain, on a 1 to 100 scale. It estimates ranking potential using link data.
DA is not a Google ranking factor or a guarantee of traffic, relevance, or publisher quality. Review those factors separately before choosing a publication.
Marketers use DA to:
What Is Page Authority (PA)?
Page Authority (PA) is Moz’s score for an individual URL, also from 1 to 100. It uses multiple signals from Moz’s link index.
The domain result displayed here does not identify an article URL. Use an exact-URL tool, such as Moz Link Explorer, when you need the PA of a particular placement page.
SEOs use PA to:
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:
A high domain score does not establish the value of an individual placement. Review the article topic, audience, indexability, link attributes, and editorial standards. PA does not measure the exact ranking benefit a backlink will deliver.
What Is a Good Domain Authority Score?
Compare domains that serve the same audience and compete for similar searches. There is no universal DA pass mark for publishers.
Use relevant competitors as context. Score bands do not certify traffic, trustworthiness, or ranking ability.
What Is a Good Page Authority Score?
Compare similar URLs using an exact-URL tool. A new article can have little recorded link history, so a minimum PA requirement can exclude useful new content.
Use relevant competitors as context. Score bands do not certify traffic, trustworthiness, or ranking ability.
Why DA and PA Matter for Your SEO Strategy
They Filter Your Link-Building Targets
Use these scores to help organize a prospect list. Before outreach, inspect relevant published articles, traffic evidence, editorial standards, and whether the proposed placement fits your campaign.
They Set Your Competitive Benchmark
Study the pages that rank for your target queries. Compare their content, intent, structure, and backlink profiles; matching an authority score alone does not establish that your page will rank.
They Guide Your Internal Linking Strategy
Review pages with useful content and relevant audiences as potential sources of internal links. Link to related resources where the connection helps readers, using clear descriptive anchor text.
They Track Your SEO Progress Over Time
Track these scores alongside organic clicks, conversions, referring domains, and published placements. Investigate changes in context rather than treating score growth as the campaign outcome.
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 Domains
Enter domains such as posticy.com, one per line. Pasting a page URL returns a domain result rather than an exact-page check.
Step 2 – Run the Check
Click Check DA & PA and wait for the results. The daily allowance is displayed beside the form. The page does not expose a data refresh timestamp, so do not assume the figures reflect today’s changes.
Step 3 – Read Your Results
The results display Domain, DA, PA, and Spam Score. Backlink counts and linking-root-domain counts are not included in the current output. A low Spam Score alone is not proof that a publisher is suitable.
