What Screaming Frog does
Screaming Frog Ltd is a privately-held UK company headquartered in Henley-on-Thames, Oxfordshire, operating a dual business model: a bootstrapped software business and a full-service SEO agency. Founded in 2010 by Dan Sharp (Founder & Director), the company employs 11-50 staff and operates without external venture or private equity capital.
The software arm develops two proprietary desktop products available on Windows, macOS, and Linux. The SEO Spider is an industry-leading website crawler used for technical SEO audits — detecting broken links, redirects, canonical issues, duplicate content, and integrating with Google PageSpeed Insights API and the AXE accessibility engine for performance and WCAG compliance analysis. The Log File Analyser enables users to upload server log files to verify bot behavior and crawler activity. Both products follow a freemium distribution model with a free 500-URL crawl tier and paid licenses for unlimited crawling and advanced features including XPath-based custom extraction. The SEO Spider also supports Markdown extraction at scale for downstream LLM and RAG pipelines.
The agency arm delivers technical SEO, search engine optimisation, pay-per-click management, paid social, content marketing, digital PR, link building, analytics consultancy, Google Ads audits, and — newly added — AI Search Optimisation services to clients ranging from international brands to SMBs (named clients include DogBuddy and Good Travel Management). The company monetises through a hybrid of self-serve software licensing (PLG, global) and direct sales of professional services (UK-leaning), distributing content through an active blog, YouTube, LinkedIn, X, and events such as brightonSEO. The company has maintained a five-year consecutive winning streak at the UK Search Awards, most recently winning Best Low Budget Campaign (SEO) in December 2025.
