Image Alt Text Best Practices for SEO
Alt text (alternative text) describes images for users who can't see them and helps search engines understand your visual content. Well-written alt text improves accessibility, boosts SEO, and can drive traffic through image search.
Why Alt Text Matters
- Accessibility: Screen readers use alt text to describe images to visually impaired users.
- SEO: Search engines use alt text to understand and index images, improving your visibility in image search.
- Fallback: Alt text displays when images fail to load, ensuring content isn't lost.
- Context: Provides context about images for better user experience.
How to Write Effective Alt Text
- Be descriptive: Describe what's actually in the image, not what you want people to see.
- Keep it concise: Aim for 80-125 characters. Screen readers may cut off longer text.
- Include keywords naturally: If relevant, include your target keyword without forcing it.
- Consider context: The same image might need different alt text on different pages.
- Don't start with "Image of": Screen readers already announce images, so this is redundant.
Alt Text by Image Type
Product images: Include product name, key features, and distinguishing details.
Infographics: Summarize the key data or message conveyed.
Screenshots: Describe what the screen shows and why it's relevant.
Team photos: Include names and roles if relevant to the content.
Decorative images: Use empty alt text (alt="") for purely decorative images.
Common Alt Text Mistakes
- Keyword stuffing: Don't cram keywords unnaturally into alt text.
- Too vague: "Photo" or "Image" provides no useful information.
- Too long: Alt text over 150 characters may be truncated by screen readers.
- Duplicate alt text: Each image should have unique, relevant alt text.
- Missing alt text: Every meaningful image needs alt text for accessibility.
