Why Image Compression Matters for SEO
Google's Core Web Vitals directly measure page loading speed. Images are typically the largest files on any webpage. Compressing them helps you:
- Improve your Largest Contentful Paint (LCP) score
- Reduce total page weight by 50-80%
- Rank higher on Google due to better PageSpeed scores
- Reduce mobile data usage for visitors
