Domain Quality Checker
Analyze domain quality factors — HTTPS, TLD type, domain length, and structure. Get links to check real DA/PA on Moz, Ahrefs, and SEMrush.
What are DA and PA?
Domain Authority (DA) is a score (1–100) developed by Moz that predicts how well a website will rank on search engines. Higher DA means more authoritative.
Page Authority (PA) is similar but measures the ranking strength of a single page rather than the entire domain.
These scores are influenced by the number and quality of inbound links, content quality, domain age, and other SEO factors.
About this tool
The free DA PA Checker helps you check Domain Authority and Page Authority of any website before building backlinks, planning a guest post, or comparing your site against competitors. Domain Authority (DA) and Page Authority (PA) are metrics developed by Moz that predict how likely a domain or page is to rank in search engine results, based on the quality and quantity of backlinks pointing to it. Because these are proprietary Moz scores, this tool analyses the domain quality factors you can observe directly — HTTPS security, top-level domain quality (.com, .in, .org score higher than obscure TLDs), domain name length, absence of hyphens or numbers, and character cleanliness — and generates a composite Domain Quality Score. For the full DA and PA numbers, the tool provides direct links to Moz's free Domain Analysis, Ahrefs' Website Authority Checker, and SEMrush's Domain Overview, all pre-filled with your domain so you can check them in one click.
