Free AI Visibility Checker scans your website and shows whether ChatGPT, Claude, Perplexity, Gemini, Google AI Overviews, and AI search tools can crawl, understand, and recommend it. It checks public signals like page clarity, crawlability, schema, sitemap, robots.txt, llms.txt, FAQs, proof content, and internal links. The free scan gives a score and first blockers; paid reports add the fix plan and implementation files.
