Why Choose Us?
Most SEO analyzer tools hide their best checks behind a subscription. Your SEO Analyzer is completely free: paste a URL and get a full audit of your meta tags, schema markup, Core Web Vitals, performance, accessibility, and AI crawler readiness without creating an account or entering a credit card.
Every result is based on real data. Scores come from Google PageSpeed Insights and Lighthouse, on-page checks come from a live analysis of your HTML, and extra context comes from the Internet Archive and the Website Carbon API. Nothing is estimated or made up.
Each issue is explained in plain English with what to fix and why it matters, so indie hackers, solo founders, students and agencies can improve their rankings without being SEO experts. Share the report with one link or download it as a multi-page PDF.
