Testing Robots.txt Rules Before Search Engines Crawl
Robots.txt files help websites control how search engines and crawlers access pages, directories, media files, and dynamic URLs. Search engines such as Googlebot read robots.txt rules before crawling a website to determine which areas should be allowed or blocked.
During technical SEO audits, incorrect robots.txt rules can block important pages, hide assets from search engines, reduce indexing, break crawl paths, or accidentally expose restricted sections. This tester helps verify whether a URL path is allowed or blocked for a selected user agent.
The tool is useful for SEO debugging, crawl optimization, migration reviews, ecommerce stores, staging environments, frontend applications, and technical SEO workflows directly inside your browser.
