Key Takeaways:
Dan Petrovic tested the use of Schema Structured Data mark-up on a webpage of his asking ChatGPT 5 to summarize it
There was no evidence of Schema even reaching the model
The answers with and without Schema were quite similar
ChatGPT itself replied multiple times that the browsing tool does not provide any Schema structured data just plain text from the raw HTML
