Marketing optimises cost-per-click to a tenth of a cent while half the visitors leave before the page even loads. Speed is the cheapest marketing channel in existence.
Numbers every CMO should know
Every extra second of load time takes 5–10 % of conversion. Google uses Core Web Vitals as a ranking factor — a slow site pays twice: worse positions and more expensive clicks. The threshold where a mobile user leaves is 3 seconds; the Slovak e-commerce average is a sorry 4.2.
Where the speed goes
The three most common causes from our audits: unoptimised images (60 % of cases), marketing scripts — heatmaps, pixels, chats, of which the average e-shop runs 23 — and a slow checkout API. All three can be fixed without replacing the platform.
Speed is not just conversion — it's SEO and brand too
A slow site pays three times: lower conversion, worse Google rankings (Core Web Vitals are a ranking factor) and a quiet loss of trust — users associate sluggishness with the brand without being able to name it. A fast site, by contrast, feels expensive and reliable before the visitor reads the first sentence. First impressions here are measured in milliseconds.
Why a redesign usually doesn't fix speed
Companies react to a slow site with a full redesign costing tens of thousands — and often the result is just as slow, because the cause was never the looks but the images, scripts and APIs. Targeted optimisation is cheaper and faster: we routinely halve the load time of an existing site without changing the platform. Measure first, then spend.
