Loading (Largest Contentful Paint – LCP): How fast the main content of your page loads.
Interactivity (First Input Delay – FID): How quickly your site responds when a user interacts with it.
Visual Stability (Cumulative Layout Shift – CLS): How much the layout of your site shifts as it loads (like when things move around unexpectedly).

Since Core Web Vitals are crucial for Google rankings, improving them will likely increase your traffic. Once your site is faster and more user-friendly, people will stay longer and visit more often.

Use tools like Google Lighthouse or PageSpeed Insights to see exactly what’s slowing your site down. Prepare the list of elements which are responsible for low page speed and CWV rules such as:

Optimize Images: Compress and resize images so they load faster.
Use Lazy Loading: Only load images as the user scrolls down, rather than loading everything at once.
Use a Fast Web Host: A good server can drastically improve your loading speed.
Minimize JavaScript and CSS: Too much unnecessary code can slow things down. You can “minify” or combine your files to make them load quicker.
Implement Caching: This saves parts of your site on the user’s device, so they don’t have to download everything every time they visit.

And use plugins like LiteSpeed Cache, W3 Total Cache, Hummingbird Performance etc for Page Speed Optimization for Core Web Vitals.
