# Core Web Vitals for Shopify Explained
Core Web Vitals are Google's key performance metrics that measure how fast, responsive, and stable your Shopify store is. Better Core Web Vitals improve user experience, boost SEO rankings, and can help increase conversions.
Let's understand the three most important Core Web Vitals.
1. Largest Contentful Paint (LCP)
LCP measures how quickly the main content of a page loads.
Good Score: Less than 2.5 seconds
To improve LCP:
- Compress images
- Use a lightweight Shopify theme
- Reduce unnecessary apps
- Optimize fonts and large banners
2. Interaction to Next Paint (INP)
