Enter any public website URL below to inspect image alt attributes, find missing alt tags, and improve accessibility and image SEO.

This tool is useful for SEO professionals, content publishers, eCommerce stores, bloggers, agencies, and website owners who want to improve accessibility and image optimization.
Image alt text is an important part of accessibility and on-page SEO. It helps describe image meaning when images cannot be seen and gives search engines more context about what the image represents.
This free Image Alt Tag Checker scans page images and helps you identify which images have useful alt text, which images are missing alt attributes, and which ones use empty alt values.
Good alt text improves accessibility for screen readers and can support image search visibility. Missing or weak alt text can reduce image usefulness for both users and search engines.
Enter your page URL into the tool and review the result list. Check how many images have alt text and which ones are missing it. For product images, editorial images, blog images, and meaningful visuals, descriptive alt text is usually recommended.
Decorative images may intentionally use empty alt attributes, but important images should normally describe their purpose clearly. The best alt text is concise, descriptive, and relevant to the image context.
