Image Alt Text Optimization Guide | SEO GEO Checker

Problem

Alt attributes provide text descriptions for images, helping search engines understand image content and enabling accessibility for screen readers. Images without alt text cannot be indexed or identified by assistive technology.

Best Practices

1. Add descriptive alt text to all meaningful images 2. Alt text should accurately describe image content 3. Include keywords naturally, avoid stuffing 4. Use empty alt (alt="") for decorative images 5. Keep under 125 characters

Example: <!-- Good examples --> <img src="seo-chart.png" alt="2024 SEO traffic growth trend chart"> <!-- Decorative image --> <img src="divider.png" alt=""> <!-- Bad examples --> <img src="photo.jpg" alt="image"> <img src="banner.jpg">

SEO Value
