AI Crawler
An automated client operated by an AI company that fetches pages for training data or live answer retrieval.
What it means
GPTBot, ClaudeBot, PerplexityBot, OAI-SearchBot, Google-Extended, CCBot and others. Some collect training data. Some fetch pages live to answer a question somebody just asked. They are not the same thing and they do not always respect the same rules, but they all read robots.txt and they all read the raw HTML response.
The part a short definition leaves out
Blocking these agents is a legitimate business decision, and plenty of publishers make it deliberately. QuickRankAI flags the block because most of the sites carrying one did not choose it. It arrived in a template, a plugin default, or a security recommendation someone applied without reading.
