What Is GPTBot? | CrawlReady AI
Learn what GPTBot is, why it appears in robots.txt, and how blocking or allowing it affects AI discovery.
GPTBot is OpenAI's robots.txt user-agent identifier. It tells site owners which automated agent is requesting pages so you can allow or disallow crawling using standard robots.txt syntax.
Why GPTBot matters for SEO and AI visibility
Traditional SEO focuses on Googlebot and Bingbot. AI-era visibility adds GPTBot, ClaudeBot, PerplexityBot, and others. Each bot reads robots.txt before crawling. If GPTBot is disallowed for /, your entire site may be treated as blocked for that agent.
Allow vs block examples
Allow entire site:
User-agent: GPTBot
Allow: /Block entire site:
User-agent: GPTBot
Disallow: /Check your site in seconds
Paste your URL into the GPTBot Checker to see whether your current robots.txt allows or blocks GPTBot on your homepage.
