The three types of AI bot traffic and how to handle them
Blog post from Vercel
AI bot traffic is increasingly significant on the web, with three main types of AI-driven crawlers contributing to a discovery process that many sites disrupt by blocking them. These crawlers, which include AI training crawlers, grounding bots, and referral systems, are essential for AI systems to gather training data, fetch real-time updates, and drive high-intent traffic to websites. While some bot traffic is malicious, a substantial portion facilitates growth and discovery when managed correctly. AI training crawlers aim to capture a comprehensive view of the web, grounding bots fetch live updates, and AI referrals bring users ready to engage. Blocking these crawlers can limit a site's visibility and growth potential, akin to early websites that blocked search engines. However, selectively allowing access to non-sensitive areas while blocking routes that offer no value for AI training can optimize discoverability and maintain security. As AI systems become integral to content discovery, making content accessible to these crawlers can significantly enhance a site's presence and authority.
