Configuring robots.txt for the AI Era: Best Practices | MarketLens

Your website’s robots.txt file is no longer just for Googlebot and Bingbot. AI search crawlers now scan the web to feed real-time search models. While some webmasters block all AI crawlers out of caution, doing so excludes their sites from AI-generated recommendations.

The optimal strategy is controlled access. In our SEO framework, we explicitly allow bots like GPTBot and PerplexityBot to access core content areas (such as services, prices, and blogs), while disallowing internal searches and admin dashboards. This ensures AI engines have access only to the structured business facts that can generate patient recommendations.
