Why your website is loading slowly (and how to fix it)

A slow website costs you customers before they ever see what you offer. Research consistently shows most visitors abandon a page that takes more than three seconds to load — and on mobile data in Cameroon, three seconds is easy to exceed.

Google also uses page speed as a ranking factor, so a slow site is both losing visitors and being pushed down the results. Here are the real causes, in the order they usually matter.

1. Enormous images (the usual culprit)

This is the number one cause, and the easiest to fix. A photo straight from a phone camera can be 4–8 MB. Ten of those on a homepage means 50 MB before any text appears.

• Resize images to the size they actually display — usually no wider than 1,600 pixels.
• Compress them (free tools online will cut file size by 70% with no visible difference).
• Use modern formats like WebP where possible.
• Enable lazy loading so images below the fold only load when scrolled to.

2. No caching

Without caching, your server rebuilds every page from scratch for every visitor. Caching stores a ready-made copy and serves that instead, which is dramatically faster.

On LiteSpeed servers, install the free LiteSpeed Cache plugin if you use WordPress — it is one of the biggest single improvements available and takes minutes.

3. No CDN

If your server is in Europe and your visitor is in Douala, every request travels thousands of kilometres. A CDN like Cloudflare stores copies of your site worldwide and serves each visitor from the nearest location.

Cloudflare's free plan is genuinely good and also adds DDoS protection and free SSL. There is very little reason not to use it.

4. Too many plugins

Every WordPress plugin adds code that must load. Sites with 40 plugins are common and almost always slow. Audit them: deactivate anything you do not actively use, and look for plugins doing jobs your theme already handles.

5. A bloated theme

Multipurpose themes that "do everything" load enormous amounts of code to support features you will never use. A lightweight theme plus a page builder is usually faster than a heavy all-in-one theme.

6. Cheap, overcrowded hosting

Some hosts pack hundreds of accounts onto one server. When a neighbour's site gets busy, yours slows down. This is why account isolation (CloudLinux) matters — it guarantees your share of resources regardless of what others are doing.

Old spinning hard drives are another cause. Insist on NVMe SSD storage, which is many times faster.

7. Unoptimised database

Over time WordPress accumulates post revisions, spam comments and orphaned data. A database cleanup plugin, run occasionally, keeps queries fast.

How to measure it properly

Test with free tools like PageSpeed Insights or GTmetrix, but do two things people forget:

• Test the mobile score, not just desktop — that is how most people see your site.
• Test from a location where your customers actually are.

And test on a real phone using mobile data. Office wifi hides problems your customers experience daily.

The fixes ranked by impact

1. Compress and resize your images
2. Turn on caching
3. Put Cloudflare in front of the site
4. Remove unused plugins
5. Move to hosting with LiteSpeed, NVMe and account isolation

The first three are free and usually take a site from painful to fast in an afternoon.
