What is robots.txt?
robots.txt tells search engine crawlers which parts of your site to index. The generator builds compliant files; the validator checks syntax and flags common mistakes.
How it works
You build rules by adding user-agent blocks with allow/disallow paths. We output valid robots.txt text and validate input against the Robots Exclusion Protocol spec.
