robots.txt Validator
Validate robots.txt syntax and check for common errors and misconfigurations.
/public//admin//private//api/public/private//A typo in a directive, Dissalow instead of Disallow, a missing colon, a Sitemap URL that isn't actually absolute, doesn't throw an error anywhere a person would notice, a crawler just silently ignores or misinterprets the malformed line, which means a robots.txt file can look complete and still be quietly broken in a way that never surfaces until crawl behavior stops matching what the file was supposed to say. This tool validates robots.txt syntax and checks for common errors and misconfigurations, catching a malformed directive itself rather than testing what a specific URL is allowed to do or auditing an already-working file's overall directives.

Useful for catching a typo'd directive before it silently gets ignored by every crawler that reads it, validating a Sitemap URL is actually formatted as an absolute address, or checking a robots.txt file's syntax is technically correct before it goes live.
