Screaming Frog SEO Spider review

Screaming Frog SEO Spider is a desktop crawler rather than a full suite, and it earns a place because site audits are one of the four jobs this list covers. The free version crawls up to 500 URLs, which is enough for many small sites. A yearly licence per user removes that limit, with the ceiling set by your machine's memory and storage. The documented feature set includes scheduling, crawl comparison, JavaScript rendering, custom extraction, spelling and grammar checks, and Google Analytics, Search Console and PageSpeed Insights integrations. It reports broken links, redirects, page titles, meta robots, hreflang, structured data and near-duplicate content. The interface is technical and data-heavy, so it suits SEO specialists more than general marketers. There is no keyword research, backlink index or rank tracking, so most teams pair it with Semrush, Ahrefs or SE Ranking. The pricing page showed us pounds and euros, so our US dollar check is pending.
