Yes — the AI Crawler Audit is 100% free with no signup, no account, and no usage limits. Just enter a URL and get instant results.
Our AI Crawler Audit runs live checks against the target website in real time. Results reflect the current state of the site at the moment you run the check — not cached or historical data.
At minimum, allow GPTBot (OpenAI/ChatGPT) and ClaudeBot (Anthropic) for AI search visibility. Google-Extended controls Gemini training data. Blocking all AI crawlers reduces your chances of appearing in AI-powered search answers.
Some crawlers separate these functions. For example, blocking Google-Extended prevents Gemini training but Google Search still indexes your site normally. ChatGPT-User handles live browsing while GPTBot handles training.
AI crawlers themselves use minimal bandwidth. The real impact is visibility: sites cited in ChatGPT, Perplexity, and Google AI Overviews receive significant referral traffic. Blocking AI crawlers may reduce this visibility.
