How to Fix Core Web Vitals (LCP, INP, CLS) on WordPress
Passing Google's Core Web Vitals assessment is essential for maintaining top search rankings and preventing mobile visitor bounce.
1. Fixing Largest Contentful Paint (LCP < 2.5s)
Preload your hero image using <link rel="preload" as="image"> and exclude the above-the-fold hero image from lazy loading attributes.
2. Fixing Cumulative Layout Shift (CLS < 0.1)
Always declare explicit width and height attributes on all images, video players, and iframe embed tags to reserve pixel space before images render.
3. Fixing Interaction to Next Paint (INP < 200ms)
Break up heavy long-running JavaScript execution tasks using requestIdleCallback and defer non-essential third-party analytics tracking scripts.
