From 3 Seconds to 0.8: Real Web Optimization Case

I recently worked with a client who had a problem: they had visits, but few sales. Analyzing their site, the problem was obvious: it took over 3 seconds to load on mobile.

The Problem

On the internet, 3 seconds is an eternity. Amazon calculated that for every 100ms delay, they lost 1% in sales. My client was losing almost half of their users before they even saw the first product.

The Solution

We performed a full audit and applied several improvements:

1. Image Optimization: Switched everything to WebP (60% weight reduction).
2. Code Cleanup: Removed old tracking scripts that were no longer used.
3. Better Server: Migrated to a modern hosting with advanced caching.

The Results

• Load Time: From 3.2s to 0.8s.
• Bounce Rate: Reduced by 25%.
• Sales: Increased by 15% the first month without extra ad spend.

The ROI (Return on Investment)

The investment in optimization paid for itself in the first 3 weeks thanks to increased sales. A fast website is not an expense, it’s an investment.
