Image missing alt attribute: what it is, why it matters, and how to fix it
One or more images on this page are missing the alt attribute entirely. The alt attribute provides alternative text that describes the image for search engines and assistive technologies.
Where this fits: content in SEO
Why image missing alt attribute hurts your rankings
Image alt text is the primary way search engines understand image content. Without it, images cannot appear in Google Image Search (a significant traffic source for many sites). Missing alt text also makes the page inaccessible to visually impaired users who rely on screen readers, potentially violating accessibility laws (ADA, EAA) and reducing your audience.
This is a medium-severity issue: individually modest, but it compounds — dozens of medium issues across hundreds of pages add up to a real quality deficit in how search engines assess the site.
How to fix it
Add descriptive alt attributes to all meaningful images. The alt text should concisely describe what the image shows and can naturally include relevant keywords. For purely decorative images, use an empty alt attribute (alt="") to indicate they should be skipped by screen readers.
<!-- Meaningful image -->
<img src="blue-running-shoes.jpg" alt="Blue Nike Air Zoom running shoes, side view" />
<!-- Decorative image -->
