Accepted Answer

Question 3

What is a DA score, exactly?

Accepted Answer

A DA (Domain Authority) score is a 1-100 estimate of how likely a domain is to rank in search results, based primarily on the strength and quantity of its backlink profile. It's a comparative metric, most useful for benchmarking against competitors or tracking change over time.

Question 4

What does PA mean in SEO?

Accepted Answer

PA (Page Authority) is the same kind of 1-100 authority score as DA, but scoped to a single page rather than the whole domain. See our DA vs PA vs DR guide for a full comparison.

Question 5

What is a good Spam Score?

Accepted Answer

On our 0-17 scale, a score of 0-3 is low risk, 4-7 is moderate, and 8+ is worth investigating further before you link to, buy, or accept content from that domain.

Question 6

Does checking a domain here affect its real DA/PA on Moz?

Accepted Answer

No. Checking a domain on DAPA Checker is a read-only lookup against free, public data sources — it has no effect on any score shown by Moz, Ahrefs, Semrush, or any other tool.

Question 7

Do I need an account to use DAPA Checker?
