You have about three seconds. That's how long most people will wait for a website to load before hitting the back button and going to a competitor. If your site is slow, you're losing business — and you might not even know it.
Speed affects everything
Website speed isn't just a technical concern. It directly impacts:
- User experience — slow sites feel frustrating and untrustworthy
- Search rankings — Google uses page speed as a ranking factor
- Conversion rates — every extra second of load time reduces conversions
- Bounce rate — slow pages have dramatically higher bounce rates
Amazon famously found that every 100ms of added latency cost them 1% in sales. You're not Amazon, but the principle holds true at every scale.
What makes a website slow?
The most common culprits are:
Oversized images
A single unoptimised photo can be 5MB or more. That's enormous. Modern image formats like WebP and AVIF can reduce file sizes by 50–80% with no visible quality loss.
Bloated page builders
Drag-and-drop website builders load massive JavaScript bundles and dozens of unused CSS files. A hand-coded site serves only what's needed.
Cheap hosting
Shared hosting packs hundreds of sites onto a single server. When traffic spikes, everything slows down. Quality hosting makes a tangible difference.
Too many plugins and scripts
Every third-party script — analytics, chat widgets, social feeds, tracking pixels — adds to load time. Be ruthless about what you include.
How to check your site speed
Two free tools will tell you everything you need to know:
- Google PageSpeed Insights — gives you a score and specific recommendations
- GTmetrix — provides detailed waterfall charts showing what's loading and when
Aim for a PageSpeed score of 90+ on both mobile and desktop.
Quick wins
If your site is sluggish, start here:
- Compress and resize images — this alone can cut load times in half
- Enable caching — so returning visitors load faster
- Minimise scripts — remove anything you're not actively using
- Upgrade hosting — move to a quality provider with SSD storage
Build fast from the start
The best approach is to build performance in from day one. A well-coded, thoughtfully built website on quality hosting will be fast without needing to retrofit optimisations later.
Speed isn't a feature — it's a fundamental requirement. If your website isn't fast, everything else you invest in (SEO, marketing, content) is undermined.
