How Do I Improve My Core Web Vitals Score?

You can find recommendations on how to improve your Core Web Vitals metrics on web.dev/fast/.  Improving metrics for your site will require web development knowledge. If you are a non-technical user, Google has some suggestions in the Search Console Help Center, but you should consider contacting a professional.

Google Search Console Core Web Vitals Data Sources

The data for the Core Web Vitals report comes from the CrUX report. The CrUX report gathers anonymized metrics about performance times from actual users visiting your URL (called field data). The CrUX database gathers information about URLs whether or not the URL is part of a Search Console property.

Fixing Core Web Vitals Issues for Non-Technical Users

1. Prioritize your issues: Google recommends fixing everything labeled “Poor” first, then prioritize your work either by issues that affect the most URLs, or by issues that affect your most important URLs. URLs labeled “Needs improvement” could be improved, but are less important to fix than Poor URLs.
2. When you’ve sorted by priority, share the report with your engineer or whomever will be updating your URLs.
3. Common page fixes:
   • Reduce your page size: best practice is less than 500KB for a page and all its resources.
   • Limit the number of page resources to 50 for best performance on mobile.
   • Consider using AMP, which almost guarantees good page loading on both mobile and desktop.
4. Test your fixes using the PageSpeed Insights testing tool (or the Chrome Lighthouse tool, if you want to use an in-browser tool).
5. When you think a particular issue is fixed, click Start Tracking on the issue details page in the Search Console Core Web Vitals report.
6. Track your validation process.
