Is Your Website Too Slow? How to Speed Up a Small Business Website

A slow website loses customers and can hold you back on Google. How to test your website's speed for free, what the scores mean and the fixes that help most.

Quick answer: Test your website for free with Google PageSpeed Insights, on mobile. The most common causes of a slow small business website are huge images, too many plugins and add-ons, cheap hosting and heavy page builders. Shrinking images, removing what you don't need and choosing better hosting fix most problems.

When someone taps on your website from Google, you have a few seconds before they get bored and go back. A slow website annoys people and costs you enquiries.

Speed problems on small business websites usually come from the same few causes.

Step 1: Test your website

Go to PageSpeed Insights (pagespeed.web.dev), type in your web address and run the test. Look at the mobile results, because that’s how most of your customers visit.

You’ll see a score out of 100 and three measures Google calls Core Web Vitals:

Measure What it checks Google’s “good” target
Largest Contentful Paint (LCP) How long the main content takes to appear 2.5 seconds or less
Interaction to Next Paint (INP) How quickly the page responds when you tap something 200 milliseconds or less
Cumulative Layout Shift (CLS) How much things jump around while loading 0.1 or less

Don’t worry too much about getting 100. Aim to pass all three.

Step 2: Fix the most common problems

Huge images

This is the number one cause. A photo straight from a phone can be several megabytes. On a website it usually only needs to be a fraction of that.

  • Resize images to the size they’re actually shown
  • Save them in a modern format like WebP
  • Use a free tool like Squoosh to shrink them before uploading

Too many plugins, apps and add-ons

Every chat widget, slider, pop-up, social feed and tracking script adds weight. Go through them and remove anything you don’t really need.

Heavy themes and page builders

Some themes and drag-and-drop builders load lots of code on every page, even code you don’t use. If your site is very slow and nothing else helps, the theme or builder may be the cause.

Cheap or overloaded hosting

Very cheap shared hosting can be slow, especially at busy times. Better hosting often makes an instant difference.

Big videos and animations

Background videos and fancy animations look nice but slow things down, especially on phones. Use them sparingly.

Step 3: Check it on a real phone

Scores are useful, but also test your site the way a customer would. Use your phone on mobile data, not Wi-Fi. Does it load quickly? Can you tap the call button easily? Does anything jump around?

Why our websites are fast

We build websites with very little code and no unnecessary plugins, so pages load quickly even on a weak phone signal. Images are compressed and the hosting is built for speed. It’s one of the reasons we build sites the way we do. Read why bespoke beats off-the-shelf for more.

Common questions

How fast should my website be?

Google’s guidance is that the main content of a page should appear within about 2.5 seconds. On a phone, the faster the better, because people give up quickly.

Does website speed affect Google rankings?

Speed is one of many things Google looks at, as part of what it calls page experience. It’s rarely the deciding factor on its own, but a slow site also loses visitors, which hurts your enquiries either way.

Why is my Wix or WordPress site slow?

Usually because of large images, lots of apps or plugins, heavy themes and animations, or slow hosting. Each one adds weight to every page.
