Screaming Frog SEO Spider is a desktop application that crawls websites to identify SEO and technical issues. It’s one of the most widely used tools among SEO professionals for comprehensive site audits.
For large or complex sites, manual SEO checks are impractical. Screaming Frog automates site crawling, helping you quickly locate broken links, duplicate content, redirect chains, missing metadata, and other performance blockers. It’s a must-have for technical SEOs, agencies, and webmasters maintaining healthy site architecture.
You install the app on your computer (Windows, macOS, or Ubuntu) and input a domain. The crawler scans internal and external URLs, collecting on-page data like titles, meta descriptions, headers, status codes, and canonical tags. You can export data to Excel, Google Sheets, or connect via API (Google Analytics, Search Console, Ahrefs, etc.).
