Frequently Asked Questions
What are Core Web Vitals?
Core Web Vitals are a set of metrics that measure real-world user experience on your website. They include Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS).
How do Core Web Vitals affect SEO?
Core Web Vitals are ranking factors in Google's search algorithm. Good scores can improve your search rankings, while poor scores may negatively impact your visibility in search results.
What is a good LCP score?
A good LCP (Largest Contentful Paint) score is 2.5 seconds or less. Scores between 2.5-4.0 seconds need improvement, and anything over 4.0 seconds is considered poor.
How can I improve my CLS score?
Improve CLS (Cumulative Layout Shift) by setting explicit dimensions for images and videos, using CSS aspect-ratio, avoiding inserting content above existing content, and preloading fonts.
What causes poor FID scores?
Poor FID (First Input Delay) is usually caused by heavy JavaScript execution, large bundle sizes, and blocking the main thread. Optimize by code splitting, reducing JavaScript, and using web workers.
How often should I monitor Web Vitals?
Monitor Core Web Vitals continuously, especially after deploying changes. Set up weekly or monthly reports to track trends and ensure performance doesn't degrade over time.
What tools can measure Core Web Vitals?
Use Google PageSpeed Insights, Chrome DevTools, Google Search Console, web-vitals library, and real user monitoring (RUM) tools to measure Core Web Vitals accurately.
Do Core Web Vitals scores differ by device?
Yes, Core Web Vitals scores often differ between mobile and desktop devices. Mobile typically shows slower performance due to network constraints and processing power limitations.
