Screaming Frog
FreemiumIndustry-standard desktop website crawler for technical SEO audits. Identifies broken links, duplicate content, crawl errors, and on-page issues.
What does this tool do?
Screaming Frog is a dual-purpose platform: a desktop website crawler tool (SEO Spider) and a complementary SEO agency. The SEO Spider is a technical SEO auditing tool that systematically crawls websites to identify on-page issues, broken links, duplicate content, crawl errors, and structural problems. It operates as a downloadable desktop application rather than a cloud-based SaaS, giving users direct control over crawl parameters and data. Beyond the crawler tool, Screaming Frog also operates as a full-service UK-based SEO agency offering search engine marketing, content marketing, link building, technical SEO consulting, and digital PR services. The company positions itself as both a software vendor and managed services provider, allowing agencies and enterprises to either self-serve with the tool or engage their consulting team.
