Such features led to the question if schema could be useful for also organizing or finding a more optimal approach to AI visibility, although this comes from a more intricate and multi-faceted procedure.

The truth is that LLMs like the famous ChatGPT don’t really need schema. They can read natural language and understand its content by itself; recognizing headings, subheadings, lists and more, without external help.

Experts must see it as a limit on your AI exposure that increases when the content is more comprehensive and well-structured.
