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