Images missing alt text

What this check looks for

Checks for <img> elements that have no alt attribute or an empty alt on images that convey meaning.

Why it matters

Alt text is read aloud by screen readers and shown when an image fails to load, so missing alt hurts accessibility for visually impaired users. It also gives search engines the context they need to rank images in Google Images and to understand surrounding content. Describe what the image shows; use an empty alt="" only for purely decorative images.

How to fix it

<!-- Describe the image's content and purpose -->
<img src="/serp-preview.png" alt="SERP snippet preview showing title, URL, and meta description">

<!-- Decorative-only image: intentionally empty alt so screen readers skip it -->
<img src="/divider.svg" alt="">
