What Is an Alt Text Checker?

An Alt Text Checker helps you review image alt attributes on a webpage. First, the tool scans the page HTML. Next, it extracts image URLs and alt text values. As a result, you can quickly find missing, empty, duplicate, or weak image descriptions.

Moreover, alt text supports accessibility because screen readers use it to describe images. In addition, useful alt text can help search engines understand image context. Therefore, checking alt text is important for image SEO, content quality, and user experience.

However, alt text should be natural and helpful. For example, a product image should describe the product clearly. Meanwhile, decorative images can use empty alt text when they do not add meaning. Consequently, the best alt text depends on the image purpose.

Missing Alt Detection

Find images with no alt attribute. Then, add descriptive text when the image supports the page content.

Empty Alt Review

Detect empty alt attributes. In some cases, empty alt text is fine for decorative images. However, important images should be described.

Duplicate Alt Warnings

Find repeated alt text across multiple images. As a result, you can make descriptions more specific and useful.

Image SEO Score

Review the score and warnings. Then, fix missing or weak descriptions to improve accessibility and image SEO.

How to Use the Alt Text Tool

First, enter the page URL you want to check. Then, click Check Alt Text. After that, review the image list, alt text status, duplicate warnings, and recommendations. Finally, copy or download the report if you need to save the audit.
