About Us

Rankszo builds free, fast SEO tools for marketers, website owners, and agencies — starting with our Domain Authority Checker, and growing into a full suite of ranking and optimization tools.

Our goal is simple: give people a quick, no-signup-required way to check the health of a domain, then offer deeper tools and higher usage limits for those who need more.

What we are building

Beyond the Domain Authority Checker, we are rolling out SEO Checker, Backlink Checker, Spam Score Checker, Keyword Difficulty Checker, and more — all from one dashboard.
