In the high-speed world of e-commerce, patience is not a virtue—it's a rarity. Amazon discovered a brutal truth that has become a fundamental law of the web: speed equals revenue.
1. The Billion Dollar Split-Second
Amazon's internal study revealed a shocking correlation: for every 100ms (0.1 seconds) of latency, their sales dropped by 1%. At Amazon's scale, that's billions of dollars lost to a blink of an eye.
This rule applies to you too. If you make $10,000/month and your site is 2 seconds slow, you could be leaving $2,000+ on the table every month.
Largest Contentful Paint (LCP) is Key
The metric that correlates most strongly with this "perceived speed" is LCP (Largest Contentful Paint). This measures when the main content (hero image or headline) is actually visible. If your LCP is over 2.5 seconds, users get frustrated and bounce.
2. Calculate Your Bleed
We built a tool specifically to quantify this loss for your business. You can input your monthly visitors, average order value, and current load time to see exactly how much cash is evaporating.
How to Fix It
To stop the bleeding, you need to be aggressive. Compress every image, use next-gen formats like WebP, and ensure your server response time (TTFB) is under 200ms.
