What Core Web Vitals means
Core Web Vitals measure how real visitors experience your pages and are part of Google's page experience signals. More importantly, slow or jumpy pages frustrate people and cost conversions. Google reports them in Search Console and PageSpeed Insights using real-user data.
Why it matters for your website
These metrics reflect what real visitors experience: how fast the main content shows up, how quickly the page responds and whether things jump around. Poor scores often mean lost leads and sales. They also feed into Google's page experience signals, though great content still matters more for rankings.
A florist's homepage scores poorly on LCP because of a huge hero image. Compressing it and loading it early brings the score into the good range and the page feels much faster.
Tips
- Check the Core Web Vitals report in Search Console for pages needing work.
- Optimize and properly size the largest image on key pages.
- Set width and height on images and ads to stop layout shifts.
Common mistakes
- Judging performance only by a single lab test instead of real-user data.
- Chasing a perfect score while ignoring content and conversion problems.
