Robots Disallow Checker

Audit which paths a site disallows in robots.txt and how many of them Google has indexed anyway.

Because: A site can ask Googlebot not to crawl certain paths, but those URLs can still end up in the index. This tool makes it easy to spot where that's happening at scale. Click the icon on any site and the extension: 1. Fetches the site's robots.txt 2. Extracts every Disallow rule that applies to Googlebot 3. Builds a Google site: query for each rule 4.
