RoborankCore Web Vitals are Google’s page experience metrics. They measure how fast your page loads (LCP), how stable it is visually (CLS), and how responsive it is to interaction (INP).
WordPress sites struggle with these metrics because themes and plugins add bloat. But the fixes are well-known and don’t require a developer.
The Three Metrics
Largest Contentful Paint (LCP)
How long until the main content is visible. Target: under 2.5 seconds. Fix: image optimization, server response time, render-blocking resources.
Cumulative Layout Shift (CLS)
How much the page layout jumps around while loading. Target: under 0.1. Fix: explicit image dimensions, font display swap, avoid injecting content above the fold.
Interaction to Next Paint (INP)
How quickly the page responds to user actions. Target: under 200ms. Fix: reduce JavaScript, defer non-critical scripts, optimize event handlers.
