Site speed and sales: why every second costs you money

A slow site loses clients before the first screen — and sinks in Google. We explain what affects speed and how to fix it.

Site speed isn't a «nice bonus for geeks» — it's direct money. Every extra second of loading lowers conversion: some people leave before it finishes. On mobile, even faster. And since 2021 speed is an official Google ranking factor (Core Web Vitals).

What Google measures

Three Core Web Vitals: LCP (when the main content appears), INP (how fast the site reacts to actions) and CLS (whether the layout «jumps»). Google takes this from real visitors — so a slow site loses both clients and rankings at once.

What most often slows it down

Heavy uncompressed images, fonts in an outdated format, excess JavaScript, dozens of builder plugins, slow hosting. Often one or two heavy elements eat half your speed — and they show up in a minute on PageSpeed Insights.

How we build fast

At RADOBO we build speed in during development, not «optimize later»: modern image and font formats, minimal excess code, caching and a CDN, clean architecture. A fast site means both higher conversion and better Google rankings — with no separate budget.
