Frequently Asked Questions

What is GEO Checker?

GEO Checker is a free suite of tools at seogeochecklist.com for Generative Engine Optimisation. It helps website owners check whether their site is properly configured to earn citations in AI-generated answers from ChatGPT, Perplexity, Google AI Overviews, Claude, and Gemini.

Who built GEO Checker?

GEO Checker was built by Mike Reynolds, a Technical SEO Specialist with 20 years of experience. He built the tool to help the SEO community navigate the shift from traditional search to AI-generated answers.

Is GEO Checker affiliated with Google, OpenAI, or Anthropic?

No. GEO Checker is an independent tool with no affiliation to Google, OpenAI, Anthropic, Perplexity, or any other AI company. It is a free, community-oriented resource.

What does the URL scanner actually check?

The scanner fetches the target site's robots.txt and llms.txt files directly, then checks: which AI bots are allowed or blocked in robots.txt, whether an llms.txt file exists at the root, whether robots.txt references a sitemap, and whether the site uses HTTPS. It does not analyse page HTML content.

How often is GEO Checker updated?

GEO Checker is updated continuously as AI engine behaviours and GEO best practices evolve. The checklist and scanner are reviewed at minimum quarterly. The current version was last updated in April 2026.

Which AI engines does GEO Checker optimise for?

GEO Checker covers the five major AI engines: Google AI Overviews, Perplexity, ChatGPT (OpenAI), Claude (Anthropic), and Microsoft Copilot. It also checks for Amazonbot and Applebot access as secondary AI signals.
