Free Robots.txt Disallow Rule Generator
Our free robots.txt disallow generator creates custom robots.txt rules to block search engine bots from crawling specific directories and files. Select from common bots (Googlebot, Bingbot, etc.) or add custom bot names. Choose from common paths to block (admin panels, private folders, PDFs, URL parameters) or enter custom paths. The tool generates properly formatted robots.txt disallow rules that you can copy or download. Perfect for webmasters, SEO professionals, and developers managing website crawling and indexing. Disallow rules tell search engine crawlers which parts of your site they shouldn't access. This is useful for blocking admin areas, duplicate content, private directories, search results, filtered pages, and file types from search indexes. The generator supports wildcards (*) for pattern matching and end-of-URL anchors ($) for precise blocking. All rule generation happens locally in your browser with instant results.
