March 3, 2026 Site Pulse 2 min read

Google’s Core Web Vitals are now official ranking factors. If you want your WordPress site to rank well in search results, you need to understand these metrics. This guide explains what Core Web Vitals are and how SitePulse helps you track them.

What Are Core Web Vitals?

Core Web Vitals are a set of specific factors that Google considers important in a webpage’s overall user experience. They measure three key aspects:

The Three Metrics

1. Largest Contentful Paint (LCP)

What it measures: How long it takes for the largest content element to become visible.

Good score: Under 2.5 seconds

What affects it: Server response time, render-blocking resources, CSS delivery, and image optimization.

2. Interaction to Next Paint (INP)

What it measures: How quickly your page responds to user interactions.

Good score: Under 200 milliseconds

What affects it: Long JavaScript tasks, excessive DOM manipulation, and event handler delays.

3. Cumulative Layout Shift (CLS)

What it measures: How stable your page layout is during loading.

Good score: Under 0.1

What affects it: Images without dimensions. Sites with good scores enjoy better search rankings, more organic traffic, improved user experience, and higher conversion rates.
