How do you approach SEO for ChatGPT (AI) purposes?

I won't hide the fact that instead of entering key phrases into Google, I'm now redirected to the GPT Chat and asking complex questions.

Over the past year, ChatGPT has become the 5th most visited website in the world, and most recently, it also recommends products.

It is clear to me that people will want their brands to be included in ChatGPT responses.

👉 How do you approach SEO or techniques that will ensure that chatpgt mentions you?
