The Need for Speed

Site speed is rarely the loudest voice in a product meeting. It’s easyScreenshot 2025-08-18 at 2.25.53 PM to put off in favor of a feature improvement or customer request. But speed is revenue. It’s one of the few levers you can pull today that will pay you back this quarter.

Look at Swappie, the online phone marketplace: they cut their mobile page load time in half and saw a 42% increase in mobile revenue. For them, that translated to millions in additional quarterly sales without adding a single new product. Vodafone trimmed load times by 31% and booked an 8% jump in online sales — that’s equivalent to adding weeks of holiday traffic overnight.

Why? Because speed determines whether customers stay long enough to buy. One to five seconds of extra load time can cut conversions by 70%. A third of customers don’t return after a slow experience. If you run a $50M e-commerce business, that’s potentially $15M of annual revenue gone because pages lag.

The fixes aren’t exotic:

  • Remove render-blocking scripts so that product pages and checkout load instantly.

  • Serve optimized images so that product pages pop, not crawl.

  • Cache intelligently so that repeat visitors get lightning-fast experiences.

This is ROI you can measure. Launch a feature and you might get a lift in one segment. Fix speed and you lift all segments, every page, every customer.

Speed isn’t a tech metric. It’s a revenue number hiding in plain sight.
