Slow website? Find what's slowing it down, then fix it properly

Most slow sites come down to a handful of fixable causes: heavy images, too many scripts, underpowered hosting. We find which ones apply to yours, fix them in order of impact, and show you the before and after.

How to tell you have this problem

If a few of these sound familiar, your site's speed is worth a proper look.

  • The main content takes longer than 2.5 seconds to appear. That is the line Google sets for a "good" Largest Contentful Paint.
  • Your mobile score in PageSpeed Insights is in the red, which Lighthouse defines as 0 to 49.
  • Pages feel fine on the office wifi but drag on a phone on mobile data.
  • Buttons don't respond straight away, or the layout jumps as images load in.
  • Customers mention it, or you find yourself apologising for the site before you send the link.

What causes it

Speed problems rarely have a single cause. These are the ones we find most often.

Oversized images. Photos uploaded straight from a camera or phone and served at full size to a screen that shows them a fraction as wide.

Too many plugins and scripts. Every chat widget, tracking tag, slider and page builder adds code the browser has to download and run before the page settles.

Underpowered hosting. Cheap shared hosting puts your site on a server with many others, so it slows down whenever they get busy.

No caching. Without caching, the server rebuilds every page from scratch for every visitor.

Bloated themes. Multipurpose themes ship styles and scripts for features you never use, and every page loads them anyway.

What it costs you

A slow page costs you twice. Visitors who are ready to call or buy wait, lose patience and go back to the search results, where a competitor is one tap away. The ones who stay form their first impression of your business from a site that feels broken.

Speed plays a part in search too, though a smaller one than it is often given credit for. Google says its ranking systems use Core Web Vitals, and also that it will still show the most relevant content even when the page experience is poor. A fast page won't outrank a better answer, but where several pages answer a search equally well, a good page experience can help.

How we fix it

  1. Step 1

    Measure before we touch anything

    We test your key pages in PageSpeed Insights and Lighthouse, check real-user Core Web Vitals where Google has the data, and record the numbers so you can see exactly what changed.

  2. Step 2

    Fix the biggest causes first

    Images resized and compressed, unused plugins and scripts removed, caching set up and render-blocking code deferred. Our website performance work runs through these in order of impact.

  3. Step 3

    Fix the foundations if they are the limit

    If the server is the bottleneck, we move the site to managed hosting. If the theme is so heavy that tuning only goes so far, we recommend a lean rebuild through our web development team, and tell you why before you spend anything.

  4. Step 4

    Retest and keep it fast

    We run the same tests again and show you the before and after. Sites slow down again as new plugins and images pile up, so we can keep an eye on it for you as part of SiteCare maintenance.

What you can check yourself

  1. 1. Run your homepage and your busiest page through PageSpeed Insights (pagespeed.web.dev) on the mobile setting, and save the scores so you can compare later.
  2. 2. Resize photos to the width they actually display at, then compress them with a tool like TinyPNG or Squoosh before uploading.
  3. 3. Deactivate and delete plugins you no longer use, testing the site after each one.
  4. 4. Remove tracking tags and widgets for tools you no longer use.
  5. 5. Ask your host whether caching is switched on and whether your plan includes a CDN.
