Image SEO Scanner

Find missing Alt tags and optimize your images for Google Image Search. Improve accessibility and SEO in one go.

Scan Images

What is an Image Scanner?

Image SEO is the process of optimizing your website's graphic content—photos, illustrations, and icons—to be more easily understood by search engines. This practice ensures your visual assets contribute to your page's overall ranking and visibility.

  • Accessibility: Enables screen readers to describe images for visually impaired users.
  • Contextual Relevance: Helps Google's crawlers connect images to the topical theme of your content.
  • Performance: Properly sized and tagged images are key to maintaining good Core Web Vitals (CLS).

Why Scan Your Images?

Image search isn't just a separate tab; it's a major traffic driver. Optimizing your visual assets is the easiest way to gain an edge over competitors who neglect their metadata.
Inclusion First
Ensure your website is accessible to everyone, regardless of how they perceive information.
Organic Discovery
Unlock traffic from Google Image Search by helping algorithms understand your visual content.

Best Practices for Image Optimization

Follow these industry standards to ensure your images are fully optimized for performance and discovery:

Quick Checklist
