Slow websites lose customers before anyone sees the offer. In South Africa, where a lot of browsing happens on mobile data, the delay is worse than most owners realise, and the causes are usually the same four.

1. Enormous images

The single most common cause. A photo straight off a phone can be 6MB. Resized properly and saved as WebP it becomes 80KB and looks identical on screen. If your gallery has twenty untouched photos, your page is asking a visitor to download a movie.

2. Too many plugins

Every plugin adds code to every page, even pages that never use it. Sliders, page builders, analytics add-ons and social feeds stack up. If a plugin has not earned its place in the last six months, remove it.

3. Cheap or distant hosting

Shared hosting packed with hundreds of sites responds slowly no matter how well the site is built. A server outside South Africa adds delay to every single request. Local, properly resourced hosting often produces a bigger speed gain than anything else on this list.

4. Fonts and scripts loaded from everywhere

Four font families, an embedded map, a chat widget and a tracking script all mean separate connections before your page can finish drawing.

What the delay actually costs

Every extra second of load time pushes more visitors to hit back. On mobile the drop-off is steeper, because the person is usually standing somewhere with something else to do. Google also uses page experience as a ranking factor, so a slow site is quietly harder to find as well as harder to use.

How to check yours honestly

Run your home page through PageSpeed Insights and read the mobile score, not the desktop one. Then do the real-world test: turn off WiFi and load the site on your phone. The number tells you where to look, the feel tells you whether it matters.

The fixes, in order of payoff

• Compress and resize every image, and serve WebP
• Remove plugins you do not use
• Move to decent local hosting with caching enabled
• Cut down to one or two font families
• Load anything non-essential after the page has drawn

Most sites I audit go from painful to comfortable with the first three alone.
