Total CrUX allows you to measure the real user experience on your site thanks to <a href="https://web.dev/vitals/" rel="nofollow ugc">Core Web Vitals</a>. 
The plugin captures and stores key metrics such as:
<ul>
<li>LCP (Largest Contentful Paint) – loading performance of the main content.</li>
<li>FID (First Input Delay) – responsiveness to first user interaction.</li>
<li>CLS (Cumulative Layout Shift) – visual stability.</li>
<li>FCP (First Contentful Paint).</li>
<li>INP (Interaction to Next Paint) – the new key responsiveness metric.</li>
<li>TTFB (Time To First Byte).</li>
</ul>
In addition, it collects extended diagnostic information (involved elements, render timings, resources, user interaction details, etc.), helping you identify which elements are negatively impacting user experience.
Inside the WordPress admin area, you’ll find:
<ul>
<li>A dashboard with aggregated site-wide metrics.</li>
<li>A “To Improve” tab showing the worst-performing pages.</li>
<li>A dropdown button with an option called “Details” that opens a right-side drawer with extended details.</li>
</ul>
With Total CrUX, you make decisions based on real user data, not just lab simulations.
