Website speed for small businesses: what matters and how to fix it

A slow website is like a shop door that sticks. Some people push harder; plenty just walk on to the next shop. Most local searches happen on mobile phones, often on a patchy 4G connection outside or between jobs, so speed matters even more for local businesses.

This guide explains what "fast" actually means, how to test your site for free, and the fixes that make the biggest difference on typical small business websites, whether you're on WordPress, Wix, Squarespace, Shopify or something else.

What "fast" means: Core Web Vitals in plain English

Google measures real-world page experience with three Core Web Vitals. According to Google's web.dev documentation, a page gives a good experience when, for at least 75% of visits:

Google's search documentation says its core ranking systems "look to reward content that provides a good page experience", and Core Web Vitals are part of that. But Google is also clear that relevance comes first: a fast page with nothing useful on it won't outrank a helpful one. Think of speed as removing a reason for customers (and Google) to give up on you.

How to test your website (free)

1. PageSpeed Insights

Go to pagespeed.web.dev and enter your homepage address. You'll see two sections:

• "Discover what your real users are experiencing": real-world data from Chrome users (the Chrome UX Report). Small sites often don't have enough visitors for this to appear. That's normal.
• "Diagnose performance issues": a lab test with a score out of 100 and a list of suggestions.

Always look at the Mobile tab first.

2. Search Console's Core Web Vitals report

If you've set up Google Search Console, the Core Web Vitals report groups your pages into Good, Needs improvement and Poor, using real data where there's enough of it.

3. Your own phone

Open your website on your phone using mobile data, not Wi-Fi. Time how long until you could actually use it. Try the menu, the phone number and the contact form. This is what your customers experience.

The most common speed problems (and fixes)

These are the issues we see most often on small business websites, roughly in order of how much difference fixing them tends to make.

1. Huge images

Photos straight from a phone camera can be several megabytes each. A homepage with ten of them is slow on any connection.

Fixes:

• Resize images to the size they're actually displayed (a full-width banner rarely needs to be wider than about 2,000 pixels; a thumbnail much less).
• Compress them. Free tools such as Squoosh (from Google Chrome Labs) can shrink files dramatically with little visible difference.
• Use modern formats like WebP or AVIF where your platform supports them.
• Use lazy loading for images further down the page (most modern platforms do this automatically), but not for the main hero image, which should load first.

2. Too many plugins, apps and widgets

Every chat widget, slider, social feed, pop-up, review widget and tracking script adds code that the phone has to download and run. This hurts loading and responsiveness (INP).

Fixes:

• List every plugin or app installed. Remove anything you don't actively use.
• Replace heavy sliders and carousels with a single strong image.
• Embed social feeds and maps only where they genuinely help, or use a simple link instead.

3. Slow or overcrowded hosting

Cheap shared hosting can be slow to respond before the page even starts loading (you'll see a high "server response time" or TTFB in PageSpeed Insights).

Fixes:

• Choose hosting with servers near your customers (UK or Europe for UK businesses) or use a CDN (content delivery network) that serves your site from locations around the world.
• Turn on caching (most WordPress hosts and plugins offer this).
• Keep your platform, theme and plugins updated.

4. Layout shift

Things jumping around as the page loads, usually because images, adverts or cookie banners load without reserved space.

Fixes:

• Make sure images have width and height set (most site builders do this for you).
• Make sure cookie banners overlay the page rather than pushing content down.
• Avoid inserting banners above existing content after the page has loaded.

5. Web fonts

Fancy fonts loaded from multiple sources can delay text from appearing.

Fixes:

• Use one or two font families at most, and only the weights you need.
• Use system fonts where possible: they're already on the device and load instantly.

6. Video backgrounds

Autoplaying background videos look impressive on desktop but are heavy on mobile. Replace with a still image on mobile, or remove entirely.

Platform-specific tips

• WordPress: choose a lightweight theme, limit plugins, use a caching plugin and an image optimisation plugin, and keep PHP updated through your host.
• Wix, Squarespace and other hosted builders: you can't control the server, but you can control images, the number of apps or widgets, fonts and video. These usually make the biggest difference.
• Shopify: review installed apps (removed apps can sometimes leave code behind in your theme), compress product images, and use a well-maintained theme.

A 30-minute speed check you can do today

1. Run your homepage through PageSpeed Insights (mobile). Write down LCP, CLS and the score.
2. Look at the "Opportunities" and "Diagnostics" list. Note anything about images.
3. Open your site on your phone using 4G. Time it. Tap the menu and the phone number.
4. List your plugins or apps. Mark any you don't use.
5. Pick the single biggest issue (usually images) and fix it this week.
6. Re-test and note the difference.

Don't chase 100

A perfect score is nice but isn't the goal. A site that loads its main content quickly, responds instantly when tapped, and doesn't jump around is doing its job. Spend your time on what customers need: clear services, proof, and an easy way to contact you. Our website must-haves guide covers the rest.
