What Triggers This Issue

This issue is triggered when images on a page have an alt attribute but are missing the alt text.

For example:

<img src="image.jpg" alt="">

How To Fix

Include descriptive alt text for images to help users and the search engines understand them better.

Where possible, decorative images should be provided using CSS background images or alternatively a null (empty) alt text should be provided (alt=””) so that they can be ignored by assistive technologies, such as screen readers.
