Why is image optimization important for SEO?

Optimized images improve page load speed (a direct ranking factor), enable Google Images discovery (a major traffic source), and improve accessibility through proper alt text — all of which contribute to better search performance.

What is the best image format for SEO?

WebP is generally the best format for the web — it's significantly smaller than JPG or PNG at equivalent quality. Use WebP with JPG/PNG fallbacks for older browsers. Avoid using uncompressed images on any public page.

How do I write good alt text for SEO?

Write alt text that accurately describes the image content, includes relevant keywords naturally, and is useful to someone who can't see the image. Keep it under 125 characters. Don't keyword-stuff or use 'image of' as a prefix.
