Generative engine optimization: what ChatGPT actually reads from your website
What ChatGPT, Perplexity and agents read from your site.
According to public descriptions, ChatGPT reads a website differently from a browser: structure is dropped, text is split into blocks, and links shift the cuts. In my simulation across 1,000 domains, the cuts landed elsewhere on 363 of 376 multi-chunk pages compared with a plain text conversion. I check what of this reaches your website and align it accordingly.

Frequently asked questions
What is generative engine optimization?
GEO stands for generative engine optimization. It makes sure that AI search tools such as ChatGPT, Perplexity or Google's AI Overviews read your website, understand it and name it as a source. Classic SEO aims at positions in the result list, GEO at mentions in the answer itself.
How do I know whether ChatGPT names my website?
I ask ChatGPT and Perplexity the questions your customers ask, usually ten to fifteen, and record which sources are named. In addition, the render check shows what technically arrives from your site. Together they show whether the cause is content or technology.
What can I do myself right away?
Check three things: whether your key content is in the HTML without JavaScript, whether every page has a clear heading structure, and whether structured data (JSON-LD) describes your company. The render check I use for this is free on GitHub.
How much does GEO cost?
The entry point is a GEO measurement for €1,500: 10 to 15 customer questions in ChatGPT, Perplexity and Google's AI Overviews, render check and work list. Together with the agentic SEO measurement it costs €2,500. Implementation modules start at €960. All prices net. All prices →
