Good alt text should describe the image in context. It should not repeat nearby captions word for word or stuff in unnecessary keywords.

Quick reminder

If an image is purely decorative, the best alt text is often an empty alt attribute rather than a forced description.

Tips

Alt text tips

Describe what matters: focus on the meaningful subject or function of the image, not every tiny visual detail.

Avoid repeating context: if nearby text already explains something fully, keep the alt text shorter and complementary.

Use empty alt for decorative images: purely decorative images often should use alt=”” so screen readers can skip them.

Keep it natural: write like a human description, not a keyword block.

Warnings

Common mistakes

Stuffing the alt text with repeated keywords instead of describing the image clearly.

Writing “image of” or “picture of” unless that phrasing is actually needed for clarity.

Using the filename as alt text without improving it into a readable description.

Forgetting that charts, diagrams, and buttons may need functional alt text, not just visual description.

How to use

How to generate better alt text

Step 1

Describe the image

Add the main subject first, then the most important visual details that help identify the image.

Step 2

Add page context

Include the page topic only when it helps users understand why the image is there.

Step 3

Choose the purpose

A product image, chart, team photo, and decorative icon should not all use the same alt text style.

Step 4

Copy the final version

Choose the cleanest variation, then copy the alt text or full HTML output into your CMS or code.

Next step

Pair image alt text with cleaner image assets

After improving alt text, keep your filenames, social image metadata, and sitemap coverage clean so image handling stays more consistent across your site.
