Frequently Asked Questions

Enter your domain into our free DA checker on the homepage to see your Domain Authority score instantly, along with PA, DR and Spam Score.

Paste the domain (e.g. example.com) into the checker box on our homepage and click 'Check Authority'. Results appear in a few seconds, no signup required.

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.

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.

Spam Score is displayed as a percentage. Moz classifies 1-30% as low, 31-60% as medium, and 61-100% as high. Results sourced from Moz are labeled Moz; otherwise the public-signal fallback is labeled Estimated.

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.

No signup, no account, and no credit card. Every tool on this site is free to use immediately.

We cache results for up to 12 hours per domain for speed. After that window, the next check re-fetches fresh data from all underlying sources.
