How to Speed Up a Slow Website

Website speed isn’t a nice-to-have — it directly affects how many visitors stay, how many convert, and how well you rank on Google. Visitors leave sites that take more than a few seconds to load, and Google uses speed as a ranking factor. If your site is slow, here’s how to fix it.

Why speed matters so much

A one-second delay can noticeably drop conversions, and slow sites lose visitors before they even see your offer. Google also factors page speed into rankings through Core Web Vitals. So speed affects both how many people reach you and how many of them stay and buy.

1. Optimise your images

Oversized images are the most common cause of slow websites. Compress images, use modern formats (like WebP), and serve them at the right size for where they appear. This alone often makes the biggest difference.

2. Get better hosting

Cheap shared hosting is a false economy — it can make even a well-built site slow. Good, appropriately-resourced hosting gives your site the foundation to load fast. If your host is the bottleneck, no amount of tweaking fully fixes it.

3. Use caching

Caching stores a ready-made version of your pages so the server doesn’t rebuild them for every visitor. It’s one of the simplest, highest-impact speed improvements — especially on platforms like WordPress.

4. Reduce bloat: plugins, scripts and code

Every extra plugin, tracking script and heavy piece of code adds load time. Remove what you don’t need, minimise and combine files, and avoid bloated themes. Lean sites are fast sites.

5. Use a CDN for a wider audience

A content delivery network (CDN) serves your site from servers closer to each visitor, speeding things up — especially useful if you have visitors across regions or countries.

Speed is the one improvement that helps everything at once — more visitors stay, more convert, and you rank higher. Fix it first.

How to measure your speed

Use Google PageSpeed Insights to test your site and see specific issues and fixes, and check your Core Web Vitals in Google Search Console. These free tools tell you exactly what’s slowing you down and what to prioritise.

The bottom line

A faster website means more visitors staying, more conversions, and better Google rankings. Start with your images (usually the biggest win), then hosting, caching, and reducing bloat. Measure with free tools, fix the biggest issues first, and your slow site becomes a fast one that works harder for your business.
