Core Web Vitals are a set of specific metrics defined by Google to evaluate the user experience of web pages. These metrics focus on three key aspects:

1. Largest Contentful Paint (LCP): Measures loading performance; ideally, LCP should occur within 2.5 seconds of when the page first starts loading.

2. First Input Delay (FID): Assesses interactivity; pages should have an FID of less than 100 milliseconds.

3. Cumulative Layout Shift (CLS): Evaluates visual stability; pages should maintain a CLS of less than 0.1.

Optimizing these metrics is crucial for enhancing user experience and can positively impact search engine rankings.
