It’s tempting to treat site speed as a technical detail for developers to worry about. It isn’t. Speed is one of the most direct levers you have on revenue — and one of the most neglected.
The conversion cost of slowness
Users form an impression in milliseconds and abandon slow pages quickly. On ecommerce and lead-gen sites alike, faster pages convert measurably better — and the effect compounds on mobile, where connections are slower and patience is shorter.
The ranking cost
Google measures real-world performance through Core Web Vitals — largest contentful paint, interaction responsiveness and layout stability — and uses them in ranking. A slow site is fighting search with one hand tied behind its back.
The brand cost
For a premium business, a sluggish site quietly undermines the impression you’re working hard to create. Fast feels expensive and well-built. Slow feels cheap, regardless of how good your work actually is.
The good news
Performance is usually a high-ROI fix. Most sites have a handful of clear culprits — unoptimised images, heavy scripts, missing caching, render-blocking resources — that a focused audit can find and a short engagement can resolve, often without changing the design at all.
