What Are Core Web Vitals?

Before diving into CrUX vs Search Console Core Web Vitals, let’s first understand what Core Web Vitals actually are.

Core Web Vitals are a set of Google’s key performance metrics that measure how real users experience a website. These include:

• Largest Contentful Paint (LCP): How fast the main content loads.

• First Input Delay (FID) / Interaction to Next Paint (INP): How quickly the site responds to user actions.

• Cumulative Layout Shift (CLS): How stable the page layout is during loading.

These metrics directly affect your Google rankings, making them essential for SEO success.

CrUX vs Search Console Core Web Vitals: The Key Difference

The most important thing to know about CrUX vs Search Console Core Web Vitals is this:

• CrUX (Chrome User Experience Report): Collects data from real-world Chrome users who visit your website. It’s based on field data from users across different devices, networks, and locations.

• Search Console Core Web Vitals: Shows data that Google uses for your site’s ranking signals. It takes CrUX data but processes it differently—focusing on URLs with enough traffic and grouping similar pages together.

👉 In short: CrUX = real-world sample data.
👉 Search Console = ranking-oriented processed data.
