You do not need to understand Lighthouse scores to know your site feels sluggish. Customers feel it too. Many leave before your phone number loads.

These five areas fix most slow local business sites. You or whoever maintains the site can work through them in an afternoon.

1. Optimise images

Resize photos before upload: width around 1600px is enough for most heroes.

Use modern formats like WebP where your platform supports them.

Do not upload 5MB phone snapshots straight to the homepage.

Lazy-load images below the fold if your theme allows it.

2. Check hosting

Budget shared hosting can be fine for low traffic, but overloaded servers slow every page. If upgrades are available on your plan, they are often the best value fix. For WordPress, managed hosting tuned for the platform beats generic £3-per-month servers when speed matters.

3. Reduce plugins and builder bloat

Deactivate plugins you do not use. Replace heavy page builders if they load dozens of scripts on every page. Sometimes a simpler theme outperforms a flashy one that looked good in a demo.

4. Fonts and video

Limit custom font families and weights.

Avoid autoplay background video on mobile.

Embed YouTube lazily rather than loading players everywhere.

5. How to test

Run Google PageSpeed Insights or similar on your homepage and a service page. Test on your phone with mobile data. Note the worst issues and fix images and plugins first. Those are the common wins.

When to rebuild instead of patch

If the site is still slow after basics, the theme or builder may be fundamentally heavy. A clean mobile-first rebuild often costs less than months of lost enquiries. Pair with our mobile-first guide when you plan scope.
