About the Image Alt Text Checker Tool

This free tool helps you check whether images on your website have proper alt text (alternative text). Alt text is essential for both SEO and accessibility purposes.

Why Alt Text is Important:

• Accessibility: Alt text helps visually impaired users understand image content through screen readers
• SEO Ranking: Search engines use alt text to understand and index images
• Context: Alt text provides context when images fail to load
• Legal Compliance: Many accessibility regulations require proper alt text

Best Practices for Writing Alt Text:

• Be specific and descriptive about the image content
• Keep alt text concise (typically under 125 characters)
• Include keywords when relevant, but avoid keyword stuffing
• Don't start with phrases like "image of" or "picture of"
• For decorative images, use empty alt text (alt="")
• For complex images (charts, infographics), provide detailed descriptions

How to Use This Tool:

1. Enter the URL of the web page you want to analyze
2. Click "Check Alt Text" to scan all images on the page
3. Review the results to identify images without proper alt text
4. Update your website's HTML to add missing alt text
