PageSpeed gives you a 100 score even if your site is vulnerable. SiteRoast checks:

PageSpeed links to Search Console. SiteRoast provides:
Speed metrics don't capture the full user experience:
PageSpeed Insights focuses only on performance metrics (Core Web Vitals, speed scores). It doesn't analyze security vulnerabilities, UX/design quality, conversion optimization, SEO beyond basics, or provide AI-powered recommendations.
Use both for different purposes. PageSpeed Insights is great for quick performance checks and Core Web Vitals. SiteRoast provides comprehensive analysis including security, design, UX, and AI-powered actionable insights that PageSpeed doesn't offer.
Both tools measure Core Web Vitals, but SiteRoast's performance score also factors in security best practices and UX elements. A fast but insecure website will score lower on SiteRoast than PageSpeed.
A 100 PageSpeed score means excellent performance, but it doesn't guarantee a secure, user-friendly, or high-converting website. SiteRoast analyzes all aspects that impact user experience and business results.
