Alt text best practices for marketing and product teams
Good alt text is short, specific, and user-focused. Here is a framework your content team can follow.
Describe the purpose, not the pixels
Alt text should explain why the image matters to the page. Decorative images should have empty alt text so screen readers skip them.
Product and ecommerce images
For product photos, include the product name and distinguishing details. Avoid repeating the surrounding text.
- Product name and key variant (color, size)
- Critical features shown in the image
- Avoid phrases like 'image of' or 'picture of'
Charts and infographics
Complex graphics need more than a short alt text. Provide a nearby text summary or data table so users get the same information.
