What to look for
- Missing alt text — every meaningful image should have descriptive alt text for accessibility and image search
- Large file sizes — images over 200KB may slow page loading and hurt Core Web Vitals
- Legacy formats — JPEG and PNG can often be replaced with WebP or AVIF for significant size savings
- Missing lazy loading — images below the fold should use
loading="lazy"to avoid blocking initial page load - Decorative images — purely decorative images should use
alt=""(empty alt), not have alt text removed entirely
