Implementation Guide
HTML Structure
```html
```
Structured Data (SEO)
json
{
"@context": "https://schema.org/",
"@type": "Product",
"image": [
"https://example.com/product-1x1.webp",
"https://example.com/product-4x3.webp",
"https://example.com/product-16x9.webp"
],

"description": "Product description..."
}
Lazy Loading Strategy
- Above fold: Load immediately (
loading="eager") - Below fold: Lazy load (
loading="lazy") - Thumbnails: Lazy load
- Zoom images: Load on hover
Automation Setup
Shopify Automation
Use apps or custom code: 1. Upload original image 2. Auto-generate WebP version 3. Create multiple sizes 4. Serve optimal format
WooCommerce Automation
php
// Add to functions.php
add_filter('upload_mimes', function($mimes) {
$mimes['webp'] = 'image/webp';
return $mimes;
});
Custom Pipeline
```yaml
GitHub Actions example
- name: Optimize Images run: | for file in images/; do cwebp "$file" -q 85 -o "${file%.}.webp" done ```
