Questions
About the SEO checker, the data and AI search.
What is StickSEO?
StickSEO is an SEO and AI search studio. Type any domain and it reads the live site and public data the way search engines and AI assistants do, then gives you a score out of 100, the reasons behind it and a short list of fixes in order of effect.
Is the website SEO checker free?
Yes. The report on this page needs no sign up and no card. Each visitor can run 12 new reports and 4 speed tests an hour, and a domain checked in the last 6 hours opens at once from the stored copy.
How is the StickSEO score worked out?
It adds up parts you can see: popularity on the Tranco list of the top one million sites, domain age from the registry, twelve technical checks on the home page and, when you press Measure speed, Google PageSpeed on a phone. Parts that cannot be measured in public, such as referring domains and search impressions, are left out rather than guessed, and the full studio adds them.
Where does the data come from?
From the live website itself (home page, robots.txt, llms.txt, XML sitemaps), the domain registry (RDAP), the Tranco research list, the Internet Archive, public DNS and Google PageSpeed Insights. Every report lists its sources and the time it was read.
Is StickSEO an alternative to Ahrefs, Semrush and Moz?
StickSEO covers the same jobs: site audit, backlink checker, keyword research, rank tracking, website authority, traffic and AI visibility. The difference is that every number names its public source, the first report is open to everyone, and AI assistants can use it directly through MCP.
How do I check if ChatGPT, Claude or Perplexity can read my site?
Type your domain above. The report reads your robots.txt and shows, one by one, whether GPTBot, OAI-SearchBot, ChatGPT-User, ClaudeBot, PerplexityBot, Google-Extended, Applebot-Extended, CCBot, Bytespider, Amazonbot and meta-externalagent are allowed, and whether you have an llms.txt file.
What is llms.txt?
llms.txt is a plain text file at the root of a website that tells AI assistants what the site is and which pages matter most. It sits beside robots.txt and sitemap.xml. StickSEO checks for it in every report.
How do I connect StickSEO to my AI assistant?
Add https://stickseo.com/api/mcp as a custom connector or MCP server in Claude, ChatGPT, Gemini CLI, GitHub Copilot, Cursor, Windsurf, Le Chat or Copilot Studio. No sign in is needed. Then ask the assistant for a StickSEO report on any domain.
Does StickSEO work in my language?
Yes. Pick any of more than 130 languages at the top of the page and the site is translated by Google Translate. The report itself can check websites in any language and any country.
