GEO Checker
GEO Checker is a free web-based tool that analyzes websites for Generative Engine Optimization (GEO), focusing on visibility and citation potential within AI-driven search engines like ChatGPT, Perplexity, Gemini, and Grok. It provides instant feedback on how well a site is structured for AI comprehension, checking metadata, content hierarchy, structured data, and other factors that influence AI model citations. The tool offers specific optimization guidance for major AI models, including tailored advice for Perplexity's real-time search, ChatGPT's structured data preferences, Gemini's multimodal understanding, and Grok's reliance on social media signals. It also includes auxiliary SEO utilities such as a Hreflang checker, Sitemap Inspector, and a Markdown to Medium converter. In addition to technical analysis, GEO Checker provides educational resources like a GEO checklist, an introduction to GEO, and a blog. The tool aims to help website owners and content creators adapt to the shift from traditional search to AI-mediated information retrieval, where brand visibility depends on being cited by generative models. It is complemented by a Chrome extension that allows for quick checks directly from the browser, making it accessible for continuous monitoring. The service requires no login and is completely free, positioning itself as an easy entry point for businesses and individuals seeking to improve their AI search performance.
