Speed is the first conversion lever
Page speed directly impacts conversion. Every additional second of load time reduces conversion by an average of 7 percent according to research published by Portent in 2025. For a store doing $100,000 in monthly revenue, a one second improvement could mean an additional $84,000 per year.
Google has made Core Web Vitals a ranking factor, which means speed improvements benefit both conversion and organic traffic. The technical investments in image optimization, code splitting, and edge caching compound.
- Sub 2 second target on mobile
