Does ChatGPT read my website directly?
Sometimes, and the distinction matters. When it answers from training it is recalling a compressed version of the web as it was, with no link to you. When it searches, it fetches live pages, reads them into context and cites them. Only the second path can be influenced this week, and it is the one that produces a citation.
Do I need to allow GPTBot in robots.txt?
If you want to be cited, yes. GPTBot, OAI-SearchBot, ClaudeBot, PerplexityBot and Google-Extended are separate agents, and a named group in robots.txt replaces the wildcard rather than extending it — so a rule written for one crawler can silently block the others. Check what your file actually resolves to rather than what you meant.
Can I submit my site to ChatGPT?
There is nothing to submit. There is no index to register with and no console to verify in. Engines find pages by crawling and by searching at the moment the question is asked, which means the only lever is being findable and quotable when that search happens.
Does an llms.txt file make ChatGPT cite me?
On its own, no. It is a convention some clients read, not a registration, and no engine has committed to honouring it. It costs an hour and it does no harm, so we publish one — but anybody selling it as the reason you will get cited is selling you an hour of work.
