GEO: How to Make Your Website Actually Visible to ChatGPT and Other LLMs

There's a new acronym in town: GEO. Generative Engine Optimization. It's the practice of making your content visible to AI-powered search engines like ChatGPT, Perplexity, and Google's AI Overviews. For developers, the technical foundation is identical to traditional SEO — but the stakes are higher.

What is GEO?

Traditional SEO gets you ranked in a list of blue links. GEO gets you included in AI-generated answers. When someone asks "what's the best tool for X?", AI search engines generate a response based on content they've crawled. If your content isn't crawlable, you're not in the answer — not in position #3, not anywhere.

The crawlers you need to serve HTML to

• GPTBot (OpenAI) — no JavaScript execution
• PerplexityBot — no JavaScript, frequent crawls
• ClaudeBot (Anthropic) — similar limitations
• Google-Extended — for Google's AI training

What makes content GEO-optimized?

• Clear, direct answers — AI systems prefer content that answers questions directly
• Structured data (schema markup) — JSON-LD helps AI understand what your content is about
• Freshness — AI systems tend to prefer recent, up-to-date content
• Citations and sources — content that cites credible sources is more likely to be cited itself

The llms.txt file

A new standard: the llms.txt file placed at the root of your site. It tells LLMs what your site is about and what content is most important. Place it at https://yoursite.com/llms.txt.
