GPTBot vs Google-Extended
Compare OpenAI's GPTBot crawler and Google's Google-Extended token — two different approaches to AI training data consent.
GPTBot, gptbotGoogle-ExtendedAnalysis
GPTBot is a standalone crawler that visits your site to collect training data for OpenAI's models. Google-Extended is not a crawler but a robots.txt token that controls whether content already crawled by Googlebot can be used for Google's AI training (Gemini models).
The key difference: blocking GPTBot stops a separate crawler from visiting; blocking Google-Extended tells Google not to use Googlebot-collected content for AI training. Both provide opt-out mechanisms, but through different technical approaches.
When to manage GPTBot
Block GPTBot to prevent OpenAI's separate crawler from accessing your content for GPT model training.
