Site speed & Core Web Vitals revenue benchmark
Is your website fast enough to convert, and what is each second costing? We measure your real-user Core Web Vitals and page speed, benchmark them against the HTTP Archive 2025 web, and translate the gap into conversions using Deloitte's speed research.
What the market looks like.

Speed is both a ranking signal and a conversion lever. Half the mobile web still fails Core Web Vitals1, which makes a fast site a competitive advantage, especially on mobile, where most traffic now lands.
