What image issues does it detect?

Missing alt text, empty alt attributes, non-optimized formats (JPG/PNG instead of WebP/AVIF), pages with excessive images, and oversized inline data URIs.

Why is alt text important?

Alt text is critical for accessibility (screen readers) and image SEO. Google uses alt text to understand image content and rank images in search results.

What image formats should I use?

WebP offers 25-35% smaller files than JPEG/PNG with similar quality. AVIF provides even better compression. Use the element with fallbacks for older browsers.
