How do you host a website on nostr in the 1st place??? I die to know

Well I am just looking into it myself tbh. Grok & Chat GPT took me through it. Looked really interesting, impossible to take down, but also non crawlable, so other than also having a traditionally hosted site mirrored onto NOSTR, I'm not sure how you'd appear in AI recommendations or Google rankings, or if there's another approach.
