Your bounce rate just spiked because your site loads in 4.2 seconds on mobile. Google’s Core Web Vitals don’t lie: users ditch slow sites faster than you can say “CLS.”
Start with these ruthless optimizations, no fluff:
-
Audit lazy-loading like it’s 2006. Half of your hero images? Probably loading full-screen before the user even clicks. Implement
loading="lazy"for below-the-fold content. Test with PageSpeed Insights—it’ll flag offenders instantly. -
Kill render-blocking scripts. Your analytics tag or outdated jQuery might be holding up layout shifts. Defer non-critical JS and inline critical CSS—your LCP score will thank you.
-
Cache aggressively. Serve static assets from a CDN with TTLs tuned for your traffic spikes. Even a 50ms reduction in TTFB drops abandonment by 17% (Smashing Magazine).
Do this today: Run Lighthouse on staging, then prioritize the top 3 fixes. Your users won’t wait.
