Implementation Guide

HTML Structure

<div class="product-gallery">
  <!-- Main Image -->
  <img
    src="product-1200.webp"
    srcset="
      product-400.webp 400w,
      product-800.webp 800w,
      product-1200.webp 1200w
    "
    sizes="(max-width: 768px) 100vw, 50vw"
    alt="Product Name - Detailed Description"
    loading="eager"
    width="1200"
    height="1200"
  >

  <!-- Thumbnails -->
  <div class="thumbnails">
    <img src="thumb-1.webp" alt="Front view" loading="lazy">
    <img src="thumb-2.webp" alt="Side view" loading="lazy">
  </div>
</div>

Structured Data (SEO)

{
  "@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"
  ],
  "name": "Product Name",
  "description": "Product description..."
}

Lazy Loading Strategy

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

// Add to functions.php
add_filter('upload_mimes', function($mimes) {
    $mimes['webp'] = 'image/webp';
    return $mimes;
});

Custom Pipeline

# GitHub Actions example
- name: Optimize Images
  run: |
    for file in images/*; do
      cwebp "$file" -q 85 -o "${file%.*}.webp"
    done

  5. Inconsistent style: Keep branding consistent
  6. Ignoring mobile: 60%+ traffic is mobile
  7. No lazy loading: Kills page performance

Test different: - Backgrounds (white vs lifestyle) - Angles - Models vs product-only - Number of images

Image SEO

  1. File names: red-running-shoes.webp (not IMG_1234.webp)
