Every year someone declares page speed a solved problem. Every year, the average site gets heavier — bigger hero images, another analytics script, one more marketing pixel — and speed quietly regresses again.
The businesses that keep winning on speed aren't doing anything exotic. They're disciplined about a few things: shipping modern image formats, deferring anything that isn't needed for the first paint, and testing on a real mid-range phone instead of a developer's laptop over fiber.
Core Web Vitals still matter. Google folds these into ranking, but the bigger effect is on conversion. A one-second delay in load time can cost double-digit percentages in conversion rate on e-commerce checkouts — that's not a rounding error, it's real revenue.
Static-first beats dynamic-by-default. Wherever content doesn't need to be generated per-request, pre-rendering it and serving it from a CDN edge node will almost always beat a server round-trip, no matter how well the server is optimized.
Third-party scripts are the silent killer. Chat widgets, review plugins, ad pixels — each one looks harmless alone. Stacked together, they're often the single biggest contributor to a slow site. Audit them quarterly and cut anything that isn't earning its keep.
Speed isn't a one-time project. It's a budget you either protect or slowly spend down with every new feature you ship.
