How do I get my product recommended by LLMs like ChatGPT?

I've seen ChatGPT and other LLMs recommend tools, products, and websites based on user queries.

As a solo maker, I'm curious,

how do these models decide what to recommend?

Is there a way to “rank” on them like we do with Google SEO?

Would love to hear if anyone has insights on:

• How LLMs learn about new products

• Whether backlinks, mentions on GitHub, Reddit, Product Hunt, etc. matter

• Any best practices to be LLM-visible

Have you tried anything that worked?
