If you want your website to rank higher on Google, it’s not just about good content or design — your website’s performance matters too. That’s where Core Web Vitals come in. These are a set of key metrics that show how fast and user-friendly your website is.

Testing your Core Web Vitals helps you understand if your WordPress theme is performing well or slowing down your site. Let’s learn how you can test it easily.

What Are Core Web Vitals?

Core Web Vitals include three important factors:

1. Largest Contentful Paint (LCP): How fast your main content loads.
2. First Input Delay (FID): How quickly your site reacts when a user clicks or taps something.
3. Cumulative Layout Shift (CLS): How stable your page layout is while loading.

If your website does well in all three, it means users enjoy a smooth and fast experience — and Google rewards that with better rankings.

How to Test Core Web Vitals

1. Use Google PageSpeed Insights:
   Go to PageSpeed Insights and enter your website URL. This free tool shows your Core Web Vitals score and gives suggestions to improve speed and performance.
2. Try Google Search Console:
   If your site is verified on Google Search Console, you can view Core Web Vitals reports under the “Experience” section. It helps track real-time user data and performance.
3. Use Lighthouse in Chrome:
   Open your website in Chrome, right-click, and choose “Inspect.” Then go to the “Lighthouse” tab and run a test. It will show detailed insights about performance, accessibility, and SEO.
4. Install a Performance Plugin:
   WordPress plugins like WP Rocket, NitroPack, or Smush can help monitor and improve Core Web Vitals automatically.
