Alt text is primarily an accessibility feature, but it also improves image context for systems that cannot see the page.

The goal is useful description, not keyword dumping.

## What It Is

Alt text is the `alt` attribute on an image. It provides a text alternative for the meaning carried by that image.

```html
<img src="/dashboard.png" alt="Launch report dashboard showing 92 overall score and 3 warnings">
```

## Why It Matters

- Screen readers announce it when the image matters.
- It preserves meaning if the image fails to load.
- It improves content clarity for non-visual systems.

## Best Practices

1. Describe the purpose or information the image adds.
2. Keep decorative images empty with `alt=""`.
3. Be concise and specific.
4. Do not repeat surrounding captions word for word unless needed.

## Common Mistakes

- Leaving meaningful images without alt text.
- Stuffing keywords instead of describing content.
- Writing `image of` when the image meaning is the important part.

## Quick Checklist

- Meaningful images have alt text.
- Decorative images use empty alt.
- Descriptions are concise and useful.

## Final Takeaway

Alt text should carry meaning, not marketing filler.
