Should You Create Separate Pages for LLMs and Google Search?

Recent discussions on Bluesky, sparked by Lily Ray and John Mueller, have raised an important question: should websites create separate Markdown or JSON pages specifically for LLMs, distinct from pages served to users and Google Search?

Google’s position is clear. According to Mueller, LLMs have been successfully training on standard HTML pages from the beginning.

So, there is no known advantage to serving alternative formats that users never see, nor is there evidence that AI systems require simplified, machine-readable pages to better understand content. If such formats materially improved AI responses, AI companies would likely promote them openly.

While some page structures may incidentally work better for humans or machines, this has little to do with file formats and more with clarity, accessibility, and content quality.

For now, optimizing high-quality HTML pages for users remains the best strategy for both Google Search and LLM visibility.
