Image SEO

Optimizing image filenames, file sizes, formats and alternative text for search and performance. Explore its purpose and practical applications.

On-page SEO & Content Strategy

이미지 SEO

Image SEO starts with descriptive filenames such as seoul-hiking-trail-map.webp rather than IMG_20240315.jpg. Reduce transfer size with suitable formats such as WebP or AVIF and write accurate alt text to support accessibility and context. Large images can delay rendering and worsen Largest Contentful Paint, linking image optimization directly to Core Web Vitals and user experience. Image search also provides a separate potential acquisition channel.
