What the DA / PA Checker Measures
Domain Authority (DA)
A 1–100 score that predicts how likely a whole domain is to rank, based on the quality and quantity of links pointing to it.
Page Authority (PA)
The same idea for a single page — useful for comparing the pages you compete with in search results.
Spam Score
The percentage of sites with similar features that have been penalized — a quick signal of link quality risk.
Linking domains
How many unique websites link to you. More relevant, authoritative linking domains usually means stronger rankings.

Still have questions? Our strategists reply within one business day.
DA is relative: compare yourself with the sites ranking for your keywords. As a rough guide, 20–40 is typical for growing local businesses and 40–60 is strong for most industries.
No. DA is a third-party metric that estimates ranking strength. Google uses its own signals, but DA is a useful benchmark for comparing sites and tracking link-building progress.
Earn links from relevant, authoritative websites through digital PR, great content and partnerships, and fix technical issues that waste link equity.
Authority scores are recalculated regularly as the link index is updated, so changes from new links can take a few weeks to appear.
