The Domain Authority Checker is a free tool that shows you the Domain Authority (DA) score of any website — a metric developed by Moz that predicts how well a domain is likely to rank on search engine results pages. DA scores range from 1 to 100, with higher scores indicating stronger ranking potential.

DA is calculated based on the number and quality of backlinks pointing to a domain, among other factors. It is widely used as a benchmark in SEO to compare website strength, qualify link building opportunities and track the impact of link-building campaigns over time.

How to Check Domain Authority

• Enter one or more domain names in the input field
• Click Check DA
• View DA score, Page Authority (PA), spam score and backlink count for each domain

How to Interpret DA Scores

• 1–20 — New or low-authority domains
• 21–40 — Growing domains with some link profile
• 41–60 — Established domains with solid authority
• 61–80 — High-authority domains (industry leaders)
• 81–100 — Elite domains (Wikipedia, major news sites)

DA is a relative metric — compare it to competitors in your niche, not to major media sites. Free bulk checking with no login needed.
