A fast website feels effortless. A slow one loses customers before they read a word — and Google notices too. Here’s what actually makes a site fast, without the jargon.
Why speed is worth money
- Conversions. Every extra second of load time measurably drops sales and enquiries.
- Rankings. Google uses speed (Core Web Vitals) as a direct ranking signal.
- Trust. Fast feels professional; slow feels broken.
Speed isn’t a nice-to-have. It’s a revenue and visibility feature.
What actually makes a site fast
- Optimised images. Photos are usually the heaviest thing on a page. Compressing and correctly sizing them is the single biggest win.
- Minimal, efficient code. Bloated templates and dozens of plugins pile on weight. Lean, purpose-built code loads faster.
- Good hosting and a CDN. Serving your site from servers close to your visitors cuts delay.
- Loading only what’s needed. Deferring non-essential scripts so the page appears before everything finishes loading.
- Caching. Reusing already-loaded assets so repeat visits are near-instant.
How to check your own speed
Run your URL through Google PageSpeed Insights. Aim for a score of 90+ on mobile. It’ll also list exactly what’s slowing you down.
The catch with DIY and template sites
Many builder and template sites are slow by default because they load heavy, generic code you can’t fully control. A custom-built, performance-first site avoids that — it ships only what your site actually needs.
At Vystra we build for a 90+ Lighthouse score as standard, because fast sites simply make more money. Want to know why yours is slow? Get a free speed audit.
