About this plugin
NaveenCodes Core Web Vitals is the most complete free performance plugin for WordPress. It measures Core Web Vitals from your actual visitors, shows you exactly which pages are slow and why, and gives you the tools to fix every issue — from CSS minification to database cleanup.
Real User Monitoring (RUM):
Unlike lab tools (Lighthouse, PageSpeed Insights), this plugin measures from your real visitors on real devices and networks — the same signal Google uses for Search ranking.
Metrics collected from every visitor:
* LCP (Largest Contentful Paint) — loading performance
* CLS (Cumulative Layout Shift) — visual stability
* INP (Interaction to Next Paint) — responsiveness
* FCP (First Contentful Paint) — time to first render
* TTFB (Time to First Byte) — server response speed
Slow Request Detection:
The collector uses the browser’s Resource Timing API to identify the slowest network requests on each page — scripts, stylesheets, images, fonts — and surfaces them in the Assets page with load time, file size and render-blocking status.
Page Analysis:
* See every published post and page with its real CWV scores
* Per-page issues with specific fix suggestions
* Quick Fix button — automatically enables the right optimizer settings
* Per-page overrides — exclude specific scripts/styles on individual pages
* Preload a specific URL (hero image, font) for a page
