Speed is the cheapest marketing you're not doing.

The Engineering Team· Web & Performance4 Jul 2026 6 min read

You can spend thousands driving traffic to a page that loses a third of its visitors before it even renders. It happens every day. The most expensive thing on your website isn't the design — it's the second-and-a-half your visitor spends staring at a blank screen, deciding whether you're worth the wait.

Slow isn't a bug. It's a leak.

Load time is the one marketing variable that costs nothing per visitor and compounds across every single one. Fix it once, and every campaign you'll ever run — paid, organic, social — converts a little better, forever. That's the definition of leverage.

This is why we build every site to be green on Core Web Vitals by design, not as an afterthought. Optimised assets, lazy-loaded heavy media, no layout shift, first paint that never makes anyone wait. It's not an engineering vanity metric. It's the cheapest customer acquisition channel you have.

Where the seconds actually hide

  • Oversized images shipping at 10× the resolution they render at.
  • Heavy scripts blocking the first paint instead of loading when idle.
  • Fonts that flash, shift the layout, and re-flow the whole page.
  • Third-party tags quietly adding half a second each.
First impressions never wait. If your page makes them wait, you've already lost the ones who mattered most.

Speed isn't the finish line — it's the floor. But it's a floor most of your competitors haven't built. Get it right, and you're converting better than them on the exact same traffic, before you've changed a single word of copy.
