About this tool
User-agent selects a crawler group. Disallow requests that matching paths not be crawled; Allow can reopen a more specific path. Sitemap points crawlers to an absolute sitemap URL. Common mistakes include an empty User-agent, duplicate or conflicting paths, and treating robots.txt as authentication or guaranteed de-indexing. Generation and testing stay in this browser.
