1. **Image Search Optimization**

  • Optimized images appear in Google Images
  • Additional traffic through image search
  • Increased visibility in SERPs

2. **User Experience**

3. **Schema Markup**

Technical Optimization

Alt Text for Product Images

Alt tags are essential for accessibility and SEO:

Best Practices:

  • Descriptive, precise texts
  • Naturally integrate keywords
  • Mention product name and main feature
  • Maximum 125 characters

Examples:

❌ Bad: "Image"
✅ Good: "Nike Air Max 270 Men's Sneaker in Black-White, Size 42"
✅ Good: "Samsung Galaxy S24 Ultra Smartphone 256GB in Titanium Black"

Optimize Filenames

Descriptive filenames improve SEO and organization:

Convention:

productname-color-size.jpg
samsung-galaxy-s24-ultra-titanium-black-256gb.jpg
nike-air-max-270-black-white-42.jpg

Rules:

  • Use lowercase
  • Hyphens instead of underscores
  • No special characters
  • Include product name and variants

Image Formats and Compression

Implement Responsive Images

HTML5 srcset for different screen sizes:

     srcset="product-small.jpg 300w,
             product-medium.jpg 600w,
             product-large.jpg 1200w"
     sizes="(max-width: 600px) 300px,
            (max-width: 1200px) 600px,
            1200px"
     alt="Product name with description">

Performance Optimization Optimization

Lazy Load

Load images only when they become visible:

Implementation:

     loading="lazy"

  • Reduced data consumption
