Why Image Optimization Matters for SEO
Optimized images improve page load speed, which is a ranking factor in Google's Core Web Vitals. Large, unoptimized images slow down your site, increasing bounce rates and hurting user experience. Proper image optimization can reduce file sizes by 50-80% without quality loss.
Beyond speed, optimized images with descriptive alt text improve accessibility and can rank in Google Image Search. Use modern formats like WebP, compress images, and serve responsive sizes for different devices.
