What each product does
Where Screaming Frog SEO Spider and PageSpeed Insights fit in the broader workflow.
Screaming Frog SEO Spider
Desktop crawler for technical SEO audits and site diagnostics.
Screaming Frog is a technical SEO staple. It is best for crawling a site and finding concrete implementation issues that affect discoverability.
It does not plan or write content. Teams use it to fix the foundation before investing in content production and ongoing publishing.
The gap to plan around is simple: research still has to become pages that buyers, search engines, and AI answers can use. Before buying, ask: Who turns the reports into pages, comparisons, citations, and updates every week?
PageSpeed Insights
Free page performance and Core Web Vitals diagnostics.
PageSpeed Insights is a seo suites tool that belongs somewhere in the AI visibility workflow. PageSpeed Insights analyzes page performance using Lighthouse lab data and Chrome UX Report field data when available.
It is most useful for technical seo teams. The buying question is whether this capability closes the loop from visibility evidence to reviewed, published content, or whether another workflow still has to do that work.
The gap to plan around is simple: research still has to become pages that buyers, search engines, and AI answers can use. Before buying, ask: Who turns the reports into pages, comparisons, citations, and updates every week?
