Last month, one of my clients saw 12% fewer conversions after their homepage hit 3.4 seconds on mobile. That’s enough time to lose most users before they even click. (Source: Smashing Magazine – real data from 2023.)
Lazy loading isn’t just nice-to-have—it’s survival mode. If your hero image loads faster than the text on mobile? Google’s already penalizing you. Test with Lighthouse and anything below 90? Fix it now.
A single unused plugin adds about 15KB per page. I once helped a client trim out deadweight plugins alone and shaved off 800ms—enough to boost their checkout rate by 6%. Run curl -I https://yoursite.com and check for responses over 1.5 seconds. If you’re past that, GTmetrix will show you where the bloat hides.
Core Web Vitals aren’t optional anymore. LCP > 2.5s? You’ll tank in the March 2024 Core Update (not some fake April 2026 event). Preload fonts, compress SVGs, and run PageSpeed Insights—it’ll tell you exactly what’s killing speed.
Action: Right now, throttle Chrome DevTools to 3G connection. If an asset fails to load? That’s your #1 priority. Last week, a client fixed a broken favicon link—immediate 15% bounce drop. Small fixes, big rewards.
