Frequently Asked Questions
What are Core Web Vitals?
LCP (Largest Contentful Paint): when largest element loads <2.5s. FID (First Input Delay): response to user interaction <100ms. CLS (Cumulative Layout Shift): stability <0.1.
Why does Google care about Core Web Vitals?
Core Web Vitals directly affect user experience. Google uses them as ranking signals. Sites with good vitals rank higher in search results.
How do I improve LCP?
Optimize server response time, use CDN, optimize images, reduce CSS/JS, lazy load non-critical resources, use modern formats.
What causes First Input Delay?
Long JavaScript execution blocks main thread. Reduce JS, use web workers, break up long tasks. React, Vue, Angular can cause FID issues if not optimized.
How do I prevent layout shifts?
Specify image/video dimensions, avoid inserting content above existing content, use transform animations instead of changing layout properties.
How often should I check?
Weekly or bi-weekly for active monitoring. Check after changes. Google Search Console shows historical Core Web Vitals data too.
