Free SEO tools

Quick checks for the things that keep a site out of Google. Free, no sign-up, made for founders and developers.

• SaaS SEO checkEnter your site and see which SaaS pages you have (pricing, alternatives, integrations, docs and more), what blocks Google from your homepage and pricing page, and the one thing to fix first. Free, no sign-up.
• Sitemap checkerFind your sitemap, check it's valid, and see whether the pages in it load and can be indexed. Free, no sign-up.
• robots.txt testerCheck whether Google and AI crawlers like GPTBot, ClaudeBot and PerplexityBot may crawl a page, and which rule decides. Test your live file or paste one.
• Indexability checkerCheck a page for everything that keeps it out of Google: errors, redirects, robots.txt, noindex, canonical tags and text that only appears after JavaScript.
• Redirect checkerSee every step a link takes before it lands: 301s, 302s, chains and loops. We also check that the http, https, www and non-www versions of your site end at the same page.
• llms.txt generatorCreate an llms.txt for your site in seconds: we read your sitemap and pages and group your key pages for AI tools like ChatGPT and Claude. Copy it or download it.
• llms.txt validatorCheck your site's llms.txt: is it there, is it written in the right format, and do its links work.
