Robots.txt Conflict Checker — Free Developer Utility

Robots.txt Conflict Checker parses your robots.txt content and flags common mistakes that can accidentally block search engines from crawling your entire site, or create contradictory rules that different crawlers may interpret differently. A single misplaced "Disallow: /" can deindex an entire website from Google without any visible warning, and directives placed before a User-agent declaration are simply ignored by compliant crawlers. This tool checks for directives appearing before any User-agent line, conflicting Allow/Disallow rules for the same path under the same user-agent, a missing Sitemap directive, absence of a wildcard User-agent: * fallback rule, and the critical "blocks everything" pattern. Each issue is labeled by severity (Error, Warning, Info) so you can prioritize fixes before deploying changes to production.

Frequently Asked Questions

Yes — 'Disallow: /' under 'User-agent: *' tells every compliant crawler not to crawl anything, which over time leads Google to drop your pages from its index.

Most major crawlers (Googlebot, Bingbot) follow the standard closely, but robots.txt is technically advisory — malicious bots can ignore it entirely. Never rely on it for security, only for crawl guidance.

It tells crawlers exactly where to find your full URL list, speeding up discovery of new and updated pages rather than relying purely on link-following.

Most crawlers use the most specific matching rule when there's a conflict, but relying on this behavior is risky — cleaner, non-overlapping rules avoid ambiguity entirely.
