Core Web Vitals: How Site Speed Affects Your Rankings
Slow sites lose rankings and customers. Learn what Core Web Vitals are and the highest-impact fixes for a faster site.
The three metrics
Largest Contentful Paint (loading), Interaction to Next Paint (responsiveness) and Cumulative Layout Shift (stability) make up Core Web Vitals.
Google uses them as a ranking signal and users abandon slow pages fast.
Highest-impact fixes
Compress and convert images to WebP, lazy-load below-the-fold media, minify CSS/JS, enable caching and reduce unused scripts.
These alone often move a site from red to green.
Measure, then improve
Use PageSpeed Insights and Search Console to find your worst pages, then fix the biggest offenders first.
