SEO · How Founders Use AI
What technical setup does my site need so AI crawlers can find, read, and cite it?
Do not block the bots that matter: OAI-SearchBot decides whether you appear in ChatGPT search (GPTBot is for training, a separate choice), plus PerplexityBot and Google's crawlers. Serve server-rendered HTML, not JavaScript-only pages, and get indexed in Bing too. Agents like ChatGPT Work, Gemini's auto browse and Claude in Chrome now visit sites to finish tasks, so use clear labels, real buttons and accessible forms. Schema helps machines parse your facts, but Google says no special AI markup is needed and it does not use llms.txt, so that file is optional.
