Seven ways to speed up a slow WordPress site

Practical fixes for slow WordPress websites, from hosting and caching to images and plugins, to pass Core Web Vitals.

By the WebsiteMatrixs team · Updated 2026-10-30 · 6 min read

Slow pages cost you visitors and rankings. Google's Core Web Vitals measure loading (LCP), responsiveness (INP) and visual stability (CLS). Here are seven fixes that help most WordPress sites.

The fixes

  • Move to managed WordPress hosting with server-level caching.
  • Add a page caching plugin and a CDN such as Cloudflare.
  • Compress images and serve WebP or AVIF formats.
  • Remove plugins you don't use, and replace heavy ones with lighter alternatives.
  • Switch to a lightweight theme or block-based design.
  • Load fonts efficiently and limit font weights.
  • Delay non-essential scripts like chat widgets and trackers.

Measure before and after

Run PageSpeed Insights on your homepage and a key service page before changing anything, then again after each fix. Search Console's Core Web Vitals report shows field data from real visitors.
