Screaming Frog SEO Spider is a powerhouse website crawler designed for in-depth SEO auditing. Deployed as a desktop application, it enables SEO professionals to swiftly crawl websites and uncover technical issues like broken links, duplicate content, and redirect chains. Through its intuitive interface, users can explore metadata, headlines, images, structured data, and pagination, all in one sophisticated dashboard.

Advanced filtering helps uncover indexing barriers such as headers missing tags, oversize pages, or uncompressed images that may degrade page speed. Custom extraction features allow targeting of bespoke content or scripts, while in-crawler SERP simulation helps mimic the search engine’s point of view. With support for integrations like Google Analytics and Search Console, it’s possible to enrich technical audits with real performance data.

CanIRank offers a modern, intelligent approach to SEO, blending actionable insights with data-driven analysis to make the craft more accessible.
