Core Web Vitals are Google's user experience metrics measuring page loading, interactivity, and visual stability, directly impacting search rankings since 2021.
Core Web Vitals are three specific performance metrics that Google uses to measure user experience quality on websites. These metrics became official ranking factors in Google's algorithm update in June 2021, making them essential for SEO success.
The three Core Web Vitals are:
Largest Contentful Paint (LCP): Measures loading performance. Good LCP occurs within 2.5 seconds of when the page first starts loading.
First Input Delay (FID): Measures interactivity. Pages should have an FID of 100 milliseconds or less.
Cumulative Layout Shift (CLS): Measures visual stability. Pages should maintain a CLS of 0.1 or less.
These metrics directly impact SEO because Google prioritizes websites that provide excellent user experiences. Poor Core Web Vitals scores can result in lower search rankings, reduced organic traffic, and decreased visibility in search results.
Improving Core Web Vitals involves optimizing images, minimizing JavaScript, using efficient caching strategies, and ensuring stable page layouts. Regular monitoring through Google PageSpeed Insights, Search Console, or specialized tools is essential.
As Timothy Flies notes, addressing Core Web Vitals isn't just about SEO—it significantly improves actual user experience, leading to better engagement and conversion rates.
