How Page Speed Directly Impacts Your Conversion Rate

Amazon found that every 100ms of added load time cost them 1% in sales. Your landing page is no different.

The data is clear: pages loading in 1 second convert 3x more than pages loading in 5 seconds. At 3 seconds, you've already lost 53% of mobile visitors.

Core Web Vitals are now a ranking factor and a conversion factor. LCP (Largest Contentful Paint) should be under 2.5s, FID (First Input Delay) under 100ms, and CLS (Cumulative Layout Shift) under 0.1.

Quick wins for speed: compress images to WebP format (70% size reduction), lazy-load below-fold content, defer non-critical JavaScript, use a CDN, and eliminate render-blocking CSS.

Measure before and after. Tools like PageSpeed Insights, WebPageTest, and Lighthouse give you actionable recommendations with estimated impact.
