JSON-LD is a must for LEO/SEO

once I added it to my microblog/thoughts feed - ChatGPT was able to read & navigate it flawlessly

before it would only retrieve partial information & fail to navigate from page to page

JSON-LD adds structure metadata that LLMs can read - instead of your 'messy' HTML, JS & CSS
