Common Robots.txt Validator Issues Found

Stale or cached data

Most teams audit using cached snapshots. Robots.txt Checker fetches the live HTML on every run, so you catch issues the day they ship.

Generic recommendations

Off-the-shelf checklists ignore your stack. Robots.txt Checker surfaces issues based on what's actually in your page source.

Missing AI-crawler signals

Most legacy tools don't audit GPTBot, ClaudeBot or PerplexityBot. We do — that's how you stay visible in AI answers.

Slow turnaround

Enterprise crawls take 6–24 hours. Robots.txt Checker returns full results in under 8 seconds, every time.
