Image Optimization for SEO: Alt Text, Compression & More

Images are often the heaviest elements on a web page. Unoptimized images slow down your site, hurt your Core Web Vitals scores, and miss opportunities for image search traffic.

Key optimization steps: add descriptive alt text to every image, compress images without visible quality loss, use modern formats like WebP, implement lazy loading, and specify width/height attributes.
