About the Robots.txt Validator
Broken robots.txt files are the silent killer of SEO. We have seen multi-million-dollar sites block their entire product catalog with a single misplaced rule. Our validator parses your robots.txt against both the RFC specification and Google-specific interpretation, cross-references against a URL list you provide, and flags any path that is blocked but should not be. It also validates AI crawler rules for GPTBot, ClaudeBot, PerplexityBot, and others.
