DA PA Checker
The free DA PA Checker displays third-party authority and spam indicators for up to three URLs in one request. Domain Authority (DA) and Page Authority (PA) are comparative SEO metrics; they are not Google ranking scores.
What Is Domain Authority?
Domain Authority estimates the relative ranking strength of a domain on a logarithmic scale. It is most useful for comparing similar websites or monitoring a domain over time. A higher number does not guarantee rankings, traffic or link quality.
What Is Page Authority?
Page Authority applies a similar concept to an individual URL. Pages on the same domain can have different values because their links, internal prominence and other signals differ.
What Is Spam Score?
Spam-related indicators identify patterns associated with sites that may present higher risk. They do not prove that a domain is penalized or harmful. Review the site, link context, ownership, traffic and relevance before making a decision.
How to Use the Checker
- Enter one complete URL per line.
- Use up to the limit shown in the tool.
- Start the analysis and wait for the metrics.
- Compare results in context rather than using one score as a pass/fail rule.
Using Metrics in Link Evaluation
Authority metrics can support prospecting, but relevance, editorial quality, real audience, placement and link attributes also matter. A relevant lower-authority site can be more useful than an unrelated site with a higher score.
Data and Availability
Metrics depend on external data providers and can change as their indexes update. Temporary limits or unavailable results do not necessarily indicate a problem with the checked website.

Yes. You can use the calculator on this page without creating an account, subject to any request limit shown in the interface.
No. Results are estimates. Official platform records, contracts, invoices, legislation and professional advice take priority.
Actual results can differ because rates, rounding, taxes, category rules, service fees or the information entered may vary.
The calculator is designed to process the values needed for the displayed result. Review the site privacy policy for general information about data and cookies.
You can use it as an initial scenario, but important pricing, tax or contractual decisions should be checked against current primary records.
Recalculate whenever a rate, cost, price, platform rule or other important input changes.
Clear the form, confirm the number format and units, then enter the values again. Compare the result with a manual calculation.
