Measure before fixing

I always start by measuring: real visitor data when it exists, then detailed tests of the important pages. That shows exactly what slows your site down, so we don’t just pile on plugins.

What actually makes a difference

The main element of the page (often an image) showing up too late
Unneeded scripts loaded on every page
Render-blocking fonts and stylesheets
Server response time and caching

Results you can check

You get the before and after measurements, taken with the same tools on the same pages. The gains are ones your visitors feel, with no dressed-up scores.

Slow WordPress site, poor Core Web Vitals, high LCP: improving WordPress performance always starts with measuring, page by page.

Frequently asked questions

Why is my WordPress site slow?

Usually because of oversized images, too many scripts (page builders, plugins, third-party tools) and underpowered hosting. A proper measurement tells you which one to fix first.

How do I improve Core Web Vitals on WordPress?

Make the main element appear sooner (LCP), cut the scripts that block interaction (INP), and reserve space for images and ads so the layout doesn't shift (CLS).

Which caching plugin should I use?

One solution, suited to your host: the server cache your host provides if there is one, otherwise a well-established caching plugin. Two caching plugins get in each other's way.

Does speed affect SEO?

Yes. Core Web Vitals are part of Google's page experience signals, and a slow site also loses visitors before they've read anything.

How do I measure my site's speed?

With PageSpeed Insights. Look at the real visitor data first, then the lab recommendations, on your most important pages.
