Slow Website? Fix Things in This Order

Cover for the article: fixing a slow website

Do not start by upgrading your hosting. Four free fixes solve most slowness, and one number tells you when upgrading is the only remaining answer.

Start with image compression, then caching, then deleting unused plugins, then updating PHP — and put the hosting upgrade last, not first. That order is deliberate: the first three are free and solve most slowness, while an upgrade costs money and may change nothing.

Anyone who moves to a pricier plan while still serving megabyte images ends up with a slow site and a bigger bill.

Measure first: two minutes

Open PageSpeed Insights or GTmetrix and read two numbers:

Time to first byte (TTFB). Under 600 ms means your server is fine and the problem is in your page. Over a second means the server or its configuration is implicated.

Page weight. Over 2 MB means images are the prime suspect.

We cover measurement and its limits in hosting and site speed.

The fixes, in order

1) Images — the biggest free win

The number one cause in nine sites out of ten.

  • Resize to what is actually displayed: a 3000-pixel image shown at 800 is pure waste.
  • Convert to WebP — a third to half the size at the same quality.
  • Enable lazy loading so images below the fold load only when reached.

The usual result: page weight down to a third, load time roughly halved.

2) Caching

Without a cache, every visit rebuilds the page from scratch: PHP runs, the database is queried, the theme is assembled. With one, a ready-made copy is served.

One caching plugin on WordPress is enough. If your server runs LiteSpeed, use its dedicated plugin — faster than a generic one.

One warning: never cache cart, account or checkout pages on stores — one visitor's cart will show to another.

3) Plugins and themes

Every plugin loads its files on every page, and every deactivated plugin remains a potential hole.

  • Delete what you do not use — do not merely deactivate it
  • Replace heavy plugins with lighter ones
  • Multipurpose themes are heavy by nature

4) PHP version

The gap between 7.4 and 8.3 is noticeable, and upgrading is a click in your control panel.

Take a backup first — an old plugin may not work on the new version. See website backups.

5) A content delivery network

Serves your images and files from the node nearest your visitor. Especially useful if your server is far from your audience, and most services have a free tier that suffices.

When upgrading is the answer

After all five, measure again. Upgrade if any one of these remains:

  • TTFB above a second despite the fixes
  • A clear gap between peak and quiet hours
  • A resource-limit email from your provider
  • The site falling over when traffic rises

And before buying, learn the renewal price, not just the promo — and why it jumps.

Common mistakes when chasing speed

Installing three optimisation plugins at once. They conflict and slow you more than they help. One is enough.

Chasing a score of 100. A 90 with a working site beats a 100 with a broken one. The score is a means, not an end.

Measuring once. Measure three times at different hours — the first run is always slowest because the cache is cold.

Ignoring mobile. Most of your visitors are on a phone and a slower network. Measure there.

The short answer

The order is the answer: images, then caching, then plugins, then PHP, then a CDN — and the hosting upgrade last.

Most sites stop at step two, already improved. And anyone who reaches step five still slow has earned the upgrade.
