A slow website frustrates visitors and can cost you enquiries. The good news is that most speed problems on small business websites come from the same few causes.

How to check your speed

Go to Google’s free PageSpeed Insights tool, paste in your web address and run the test. Check the mobile result first, since most local visitors are on phones. The report lists what’s slowing your page down.

Cause 1: Huge images

This is the most common problem I find. A photo straight from a camera or phone can be many times larger than a web page needs.

The fix: resize images to the size they actually display, compress them, and use modern formats like WebP where your platform supports it.

Cause 2: Too many plugins or add-ons

On WordPress, every plugin can add extra code to your pages. Over the years, sites collect plugins that nobody uses anymore.

The fix: review your plugins, remove the ones you don’t need, and replace heavy ones with lighter options.

Cause 3: A heavy theme or page builder setup

Some themes load lots of features you never use. Complex layouts with many nested sections also add weight.

The fix: use a lightweight theme and keep layouts clean. Simpler pages are often faster and easier to read.

Cause 4: Slow hosting

If your server is slow to respond, everything else waits. Very cheap shared hosting can struggle when traffic grows.

The fix: choose a reliable host with servers reasonably close to your customers, and turn on caching.

Cause 5: Too many fonts and scripts

Every font weight, tracking code, chat widget and embedded video adds requests.

The fix: limit fonts to the weights you use, remove old tracking codes, and load videos only when someone clicks play.

Cause 6: No caching

Caching saves a ready made copy of your pages so they don’t have to be rebuilt for every visitor.

The fix: many hosts include caching. Turn it on, and test your site afterwards to make sure everything still works.

What about Webflow and Framer?

Hosted platforms handle servers and caching for you, so the main things to watch are image sizes, fonts and third party scripts. I compare the platforms in Webflow vs Framer vs WordPress.

Speed checks belong in your regular routine. Add them to my monthly website maintenance checklist. If your site needs more than a tune up, read 9 signs your website needs a redesign.
