Optimize images for SEO by evaluating alt text, file sizes, formats, and loading behavior. This ensures descriptive accessibility text, modern WebP/AVIF adoption, responsive srcset implementation, and lazy-loading practices to boost LCP and CLS scores.

Implement responsive images by enforcing srcset and sizes attributes on img elements. This directs browsers to download appropriately sized image assets based on device viewport, significantly reducing file payloads while preserving visual quality across breakpoints.

Apply lazy loading and fetchpriority to img elements when optimizing web vitals. Use lazy loading for off-screen images to defer downloads, and set fetchpriority to manage critical above-the-fold rendering, directly improving LCP and CLS metrics.

Write effective alt text by ensuring all images have descriptive, context-relevant descriptions. Avoid vague or decorative-only text, validating that every image asset provides meaningful accessibility and search engine context for page components.

Converting images to modern formats like WebP or AVIF improves page load speed by applying superior compression. This reduces file size thresholds below standard formats, delivering high visual quality with smaller payloads for faster web page rendering.

Lazy loading can cause layout shifts when image dimensions are unspecified, degrading CLS scores. Fix this by evaluating loading behavior and enforcing proper size attributes alongside responsive srcset to reserve space during page rendering.
