What each product does
Where Sitebulb and PageSpeed Insights fit in the broader workflow.
Sitebulb
Technical SEO audit software with crawl insights and reports.
Sitebulb is a technical SEO auditing platform for teams that need crawl diagnostics with clearer visual explanations than raw exports.
It is strongest for finding and explaining technical problems. Content strategy, writing, and publishing still live elsewhere.
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?
