Core Web Vitals are Google’s way of measuring how good your website is for users. In 2025, they matter more than ever for your rankings and user experience.

Understanding Core Web Vitals and Google Search Results

Google wants to give the best experience to users. So, it checks how fast your website loads, how stable it feels, and how quickly it reacts to user actions. These are called Core Web Vitals.

How to Measure Core Web Vitals?

You can use these tools:

- Google PageSpeed Insights

- Lighthouse

- Google Search Console (CWV report)

- Web.dev

Core Web Vitals and Their Impact on SEO

If your website has poor Core Web Vitals, your ranking can drop - even if your content is good. So improving CWV helps in:

- Getting higher rankings

- Reducing bounce rate

- Increasing page engagement

How to Improve Core Web Vitals?

Tips:

- Compress images (use WebP format)

• FID: First Input Delay (replaced by INP)
