# Is Your Website Invisible to ChatGPT Search? The Hidden Cost of Blocking AI Crawlers

If you blocked OpenAI's web crawler from training on your data, your site is not listed as a source in ChatGPT Search. That's the new Faustian bargain. If ChatGPT Search catches on, then you're not included. Exhibit A: asking ChatGPT Search about the 1924 NY Times Op-Ed about immigration (which does exist). No sources listed. Exhibit B: asking ChatGPT Search about blog posts from Christopher Penn about email marketing attribution. Tons of sources from my website, which I keep open to AI crawlers. The bargain is explicit: hand over your data or be excluded from search results.
