📝 About Screaming Frog
Screaming Frog’s SEO Spider crawls a website the way Google’s bot does — following links, fetching pages, and cataloging everything that matters: broken links, redirect chains, duplicate titles, missing meta descriptions, orphaned pages, malformed canonicals, and slow responses by the thousand.
Technical SEOs consider it non-negotiable. Point it at a site and within minutes you have a spreadsheet-grade inventory of problems that silently bleed rankings. For large sites, it chews through hundreds of thousands of URLs where browser tools collapse.
The free version audits up to 500 URLs — enough for most small sites entirely. When an audit needs to be exhaustive rather than sampled, this is the frog you want.
