Alt-text (alternative text) allows your ad creatives to be read by screen readers and increases the accessibility of your ads. These short image descriptions provide details about the ad and prompt your call to action.
How to add alt-text to creatives
- Navigate to the Creatives step of a campaign
- Add image description in the alt-text field. This will automatically apply to all creatives included in the campaign
- Once creatives are added, specify unique alt-text for each creative, if needed
- Keep it short and descriptive. Limit description to 125 characters, since most screen readers will stop reading longer alt text
- Do begin with “ad” or “advertisement”
- Don’t add “image of” or “picture of”
- Focus on the call to action
