About Screaming Frog
Screaming Frog's SEO Spider crawls your site like a search engine and surfaces the technical problems that hold rankings back — broken links, redirects, duplicate or missing titles, canonical and indexability issues. The free version handles up to 500 URLs, which covers most small sites.
The fastest way to find on-site technical issues, and genuinely free for smaller sites. A staple of every technical SEO audit.
