  1. 1Enter your site’s full URL, including https://.
  2. 2Run the scan to check llms.txt, robots.txt, and structured data.
  3. 3Review each pass or fail and the specific fix suggested.

Frequently asked questions

What is GEO (Generative Engine Optimization)?

GEO is the practice of optimizing your website so AI search engines like ChatGPT, Perplexity, and Google’s AI Overviews can find, understand, and cite it. It builds on classic SEO by adding signals such as an llms.txt file, structured data, and clean, crawlable content.

What does this analyzer check?

It inspects your site for an llms.txt file, a valid robots.txt, and schema.org structured data — the core signals AI crawlers use to discover and interpret your content. You get a per-check pass or fail with tips to close any gaps.

What is an llms.txt file?

llms.txt is a plain-text file at your domain root that tells large language models which content matters and how to use it, similar to how robots.txt guides search crawlers. Adding one helps AI engines surface accurate information about your site.

Should I block AI crawlers like GPTBot in robots.txt?

Only if you do not want your content used or cited by AI products. Blocking GPTBot, ClaudeBot, or PerplexityBot keeps those crawlers out, but it also means the assistants behind them cannot read your pages to cite them. If AI visibility is the goal, allow them and block only private paths.
