10 Image SEO Best Practices
1. Use Descriptive File Names
❌ Bad: IMG_1234.jpg
✅ Good: red-running-shoes-nike-air-max.jpg
Tips: - Use hyphens (not underscores) - Include target keywords - Keep it concise (3-5 words)
2. Optimize Alt Text
Purpose: - Accessibility (screen readers) - SEO (Google reads alt text) - Fallback when image doesn't load
Example:
html
<img src="red-running-shoes.jpg" alt="Red Nike Air Max running shoes on white background">
Tips: - Describe the image - Include keywords naturally - Keep under 125 characters - Don't keyword stuff
3. Compress Images
Impact: - 70% smaller file size - 50% faster load time - Better Core Web Vitals
Recommended tools: - Imagic AI Compressor - Target: 80% quality, <500KB
4. Choose the Right Format
| Format | Use Case | Size | |--------|----------|------| | WebP | Most images | Smallest | | JPEG | Photos | Small | | PNG | Graphics, transparency | Larger | | SVG | Logos, icons | Smallest |
Recommendation: Use WebP with JPEG fallback
5. Implement Lazy Loading
html
<img src="image.jpg" loading="lazy" alt="Description">
Benefits: - Faster initial page load - Better Core Web Vitals - Saves bandwidth
6. Create Image Sitemaps
xml
<url>
<loc>https://example.com/page</loc>
<image:image>
<image:loc>https://example.com/image.jpg</image:loc>
<image:title>Image Title</image:title>
<image:caption>Image Caption</image:caption>
</image:image>
</url>
7. Add Structured Data
json
{
"@context": "https://schema.org",
"@type": "ImageObject",
"contentUrl": "https://example.com/image.jpg",
"name": "Image Title",
"description": "Image description"
}
8. Optimize Image Dimensions
Guidelines: - Match display size - Use responsive images - Avoid resizing with CSS/HTML
Example: ```html <img srcset="small.jpg 400w, medium.jpg 800w, large.jpg 1200w" sizes="(max-width: 600px) 400px, 800px" src="medium.jpg" alt="Description"
```
9. Use Captions
Why: - Captions are read 300% more than body text - Provide context for images - Improve engagement
10. Host Images on Your Domain
Benefits: - Brand consistency - Full control - Better analytics
