Image SEO is crucial for improving your website's search engine visibility. Here are the key strategies:

1. Use descriptive filenames: Instead of 'IMG001.jpg', use 'red-apple-fruit.jpg'

2. Add alt text: Always include meaningful alt attributes for accessibility and SEO

Proper SEO practices improve visibility

3. Optimize file sizes: Compress images without losing quality to improve page load speed

4. Use proper image formats: Choose WebP for modern browsers, JPEG for photos, PNG for graphics

5. Implement structured data: Use schema markup for images when appropriate

6. Create image sitemaps: Help search engines discover and index your images

Sitemaps help search engines find your content

7. Use responsive images: Serve different sizes for different devices

By following these practices, you can significantly improve your website's image SEO performance and overall search rankings.
