What's causing my Core Web Vitals issues and how can I fix them?
Answer: Common causes and solutions:
-
Largest Contentful Paint (LCP): Optimize server response time, implement resource prioritization, and optimize critical rendering path.
-
First Input Delay (FID): Reduce JavaScript execution time, break up long tasks, optimize event handlers.
-
Cumulative Layout Shift (CLS): Add width/height attributes to images, ensure ads/embeds have reserved space, and avoid inserting content above existing content.
