- ✓ For the fastest page loads, keep each image under 200 KB. Images are the single biggest contributor to slow page load times.
- ✓ Use JPG as a fallback for browsers that do not support WEBP. Most CMS platforms (WordPress, Shopify) handle this automatically.
- ✓ Google's Largest Contentful Paint (LCP) metric — a Core Web Vitals ranking factor — is most often caused by large hero images. Compress and size hero images carefully.
