Image Alt Tag – Best Practices for Writing Alt Text
The image alt tag (alt attribute) should follow these best practices:
- Be specific and descriptive: Describe what is actually depicted in the image, not what you want the image to mean.
- Keep it concise: Aim for 80–120 characters; avoid repeating words or keyword stuffing.
- Avoid redundant phrases: Do not include phrases like "image of" or "picture of". Search engines and screen readers already know it's an image.
- Include relevant keywords naturally: If the image depicts a product, include the product name and key attributes.
- Decorative images: For purely decorative dividers or background icons, use an empty alt attribute (
alt="") so screen readers skip them.
