WEBSITE AEO AND GEO CHECKER
AI Crawler Checker — Is GPTBot Blocked From Your Website?
AI crawler access is a foundation for AI search visibility. If key bots are blocked in robots.txt, your pages cannot be fetched and cited, no matter how strong the content is. This landing page explains what AI crawlers do, why sites block them, and how our checker audits access for GPTBot, ClaudeBot, PerplexityBot, and more.
What This Checker Audits
We fetch your robots.txt and evaluate access rules for 14 well-known AI crawlers across three tiers. Tier 1 crawlers are the most important for citations and live retrieval. Tier 2 covers secondary AI bots. Tier 3 covers training-focused crawlers that many sites choose to block. The report shows whether each bot is explicitly allowed, explicitly blocked, or blocked by wildcard rules.
Common robots.txt Mistakes
- Using `User-agent: *` with `Disallow: /` which blocks everything.
- Blocking citation bots unintentionally while trying to block training bots.
- Multiple conflicting groups that do not match the intended crawler names.
- Serving an HTML page at /robots.txt due to redirects or misconfiguration.
