You found this guide through search. Use the same approach: simple, fast changes that move the needle. Start with caching and images, then trim bloat and verify speed.

Why speed matters

Faster pages improve conversions and SEO. These quick wins are safe for beginners and deliver noticeable speed without code changes.

Step-by-step

1

Enable caching

Install a caching plugin (WP Rocket, W3 Total Cache, or LiteSpeed Cache if your host supports it). Turn on page cache and browser cache.

2

Compress and lazy-load images

Use an image plugin (Imagify, ShortPixel, Smush). Convert to WebP, compress existing media, and enable lazy-load for below-the-fold images.

3

Remove bloat plugins

Deactivate and delete plugins you do not use. Replace heavy multi-tools with lighter single-purpose plugins.

4

Optimize CSS/JS

Minify and combine where safe. Defer non-critical JS. Exclude files that break layouts from minification if needed.

5

Use a CDN

Turn on your host’s CDN or use Cloudflare free tier. Serve static assets from the CDN for faster global loads.

6

Check your homepage and key pages

Test homepage, product pages, and checkout. Remove large sliders or autoplay video that slows first paint.

Checklist

  • Caching plugin enabled
  • Images compressed and lazy-loaded
  • Unused plugins removed
  • CSS/JS minify/defer set
  • CDN enabled
  • Homepage and key pages retested

FAQ

Will minifying files break my site?

Sometimes. If layouts break, exclude the offending CSS/JS from minification and keep caching on.

Do I need a paid CDN?

No. Cloudflare free or your host’s CDN is often enough for small to medium sites.

What about Core Web Vitals?

These quick wins improve LCP and FCP. For deeper gains, optimize hosting, fonts, and reduce third-party scripts.

Final thoughts

Speed is achievable fast: cache, compress images, trim bloat, defer scripts, and enable a CDN. Re-test after each change and keep it simple—small steps add up.
