About GEO Checker | Free GEO and SEO Tools

What is GEO Checker?

GEO Checker is a free suite of tools at seogeochecklist.com designed to help website owners, SEO professionals, and digital marketers optimise for Generative Engine Optimisation (GEO): the practice of appearing in AI-generated answers from ChatGPT, Perplexity, Google AI Overviews, Claude, and Gemini.

AI-generated answers are increasingly displacing traditional blue-link search results. Sites that are not properly configured for AI crawlers and structured data are being left out of these answers regardless of their traditional search rankings. GEO Checker was built to make that analysis fast, free, and accessible to everyone.
