Screaming Frog

Screaming Frog is a search marketing agency based in the UK that also publishes SEO software. Its best-known product, the Screaming Frog SEO Spider, is a desktop application for Windows, macOS and Linux that crawls a website the way a search engine would and reports technical issues: broken links, redirects, duplicate content, missing or badly formed titles and meta descriptions, and problems with directives, canonicals and sitemaps. A free version crawls a limited number of URLs and a paid licence removes the limit. The company also makes the Log File Analyser, and its agency side provides SEO, paid search and content marketing services. The tools are used by SEO consultants, agencies and in-house marketing teams.
