Core Web Vitals are no longer optional. They are a confirmed ranking factor. But deciphering the acronyms can feel like reading a medical chart in Latin. Let's translate.

1. The Vitals Explained

LCP (Loading): The time it takes for the largest content to appear. Think of this as the "Wait Time" in a doctors office. Anything over 2.5s is painful.

CLS (Stability): Visual stability. Does the layout shift? This is like a chair that collapses when you sit on it.

Clinical Note:

INP (Interactivity): The newest metric. Interaction to Next Paint measures how quickly the page responds to a click. A delay >200ms feels sluggish and broken.

The Debugging Toolkit

You don't need to be a developer to diagnose these issues.
1. PageSpeed Insights: The standard lab test.
2. Chrome DevTools: For granular element inspection.
3. SiteSpeed Scan: Our tool, which combines these metrics into a simple "Health Score".

2. Treatment Plan

Don't panic. Start with the basics: fast hosting (TTFB), optimized images (WebP), and caching. Test your site frequently. The web changes constantly, and your health checkup shouldn't be a one-time event.
