There is no single right answer, and the trade-off is real. Blocking a training crawler stops that model from learning on your content, but it can also stop your brand from being cited in the AI answers your buyers now read. Use this quick framework. Your goal What to do You want to be cited in ChatGPT, Perplexity, and Google AI **Allow** GPTBot, PerplexityBot, Google-Extended, ClaudeBot You publish premium or paywalled work you do not want used for training **Disallow** training crawlers, keep real-time agents allowed You want ChatGPT to fetch your page live but not train on it Allow `ChatGPT-User`, disallow `GPTBot` You are unsure Allow AI crawlers. Visibility is usually worth more than the risk for most sites. ### How to verify your robots.txt is working 1. Upload the file to your root so it loads at `yourdomain.com/robots.txt`. 2. Open that URL in a browser to confirm it is live and readable. 3. Remember that robots.txt is a public request, not a lock. Well-behaved crawlers obey it; it does not physically prevent access, so never use it to hide private data. 4. Re-check after any CMS or host migration, since some platforms serve their own robots.txt by default. ### Get the AI Crawler Control Kit Enter your name and work email to download your robots.txt, a matching llms.txt starter, and a plain-English AI crawler guide.

The standard way is a robots.txt file at your site root that names each AI crawler and disallows it, for example User-agent: GPTBot followed by Disallow: /. Well-behaved crawlers such as GPTBot, ClaudeBot, PerplexityBot, and Google-Extended honor these rules. This tool generates that file for you. Note that robots.txt is a request, not a hard block, so it stops compliant bots but is not a security control. The most common method is robots.txt with a Disallow rule for each AI user-agent. For stricter enforcement you can also block the crawler user-agents or IP ranges at your CDN or firewall, for example with Cloudflare's bot controls, which physically refuses the request rather than relying on the crawler to obey. Most sites start with robots.txt and only add firewall rules if they see bots ignoring it. For most sites, yes. Allowing crawlers such as ChatGPT-User, PerplexityBot, and Google-Extended is how your brand becomes eligible to be cited in AI answers, which is a fast-growing source of qualified traffic. Block them only if you have a specific reason, such as premium content you do not want used for model training. You can allow the real-time answer crawlers while blocking the pure training crawlers. AI crawlers fetch web pages for two purposes: training, where a crawler like GPTBot or ClaudeBot collects text to train a model, and retrieval, where a crawler like ChatGPT-User or PerplexityBot fetches your page live to answer a user's question and often cites it. Training and retrieval are separate, which is why you can block one and allow the other. No. Google uses Googlebot for search rankings, not AI-specific crawlers, so blocking GPTBot or ClaudeBot has no effect on your organic positions. The one exception is Google-Extended: blocking it can keep your content out of Google's AI Overviews, but your traditional search rankings remain unaffected. Upload the generated robots.txt to your website's root directory so it is reachable at yourdomain.com/robots.txt. Most hosts let you upload via FTP, a file manager, or CMS settings. Name the file exactly robots.txt and keep it in the root, not a subdirectory, then open the URL in a browser to confirm it is live. ![Background](/background/cta_background.jpg) ### Ready to turn AI search into high-intent buyers?
