2. Responsive Image Implementation

<picture> <source srcset="image-320.avif 320w, image-640.avif 640w, image-1280.avif 1280w" sizes="(max-width: 768px) 100vw, (max-width: 1200px) 50vw, 33vw" type="image/avif" /> <source srcset="image-320.webp 320w, image-640.webp 640w, image-1280.webp 1280w" sizes="(max-width: 768px) 100vw, (max-width: 1200px) 50vw, 33vw" type="image/webp" /> <img src="image-640.jpg" srcset="image-320.jpg 320w, image-640.jpg 640w, image-1280.jpg 1280w" sizes="(max-width: 768px) 100vw, (max-width: 1200px) 50vw, 33vw" alt="Detailed description of image content" loading="lazy" width="640" height="480" /> </picture>

3. Performance Optimization

• Compression: Optimize file size while maintaining visual quality
• Lazy Loading: Load images as they enter the viewport
• Critical Images: Preload above-the-fold images
• CDN Delivery: Use global content delivery networks
• Cache Headers: Set appropriate browser caching

Alt Text and Content Optimization

Alt Text Best Practices:

Poor Alt Text: "image1.jpg" or "photo"

Good Alt Text: "Red Nike running shoes on wooden floor with morning sunlight"

Keyword Stuffing: "best running shoes cheap running shoes buy running shoes"

Natural Keywords: "Professional marathon runner wearing lightweight carbon-plate running shoes"

File Naming Strategy

• Descriptive Names: Use meaningful, keyword-rich file names
• Hyphens for Separation: Use hyphens instead of underscores or spaces
• Lowercase Convention: Keep all file names in lowercase
• Avoid Generic Names: Skip "image.jpg", "photo.png", etc.

Good Examples:
• modern-kitchen-design-white-cabinets.webp
• 2026-tesla-model-s-interior-dashboard.jpg
• organic-coffee-beans-roasting-process.avif

Contextual Optimization

• Surrounding Content: Ensure images relate to nearby text content
• Caption Optimization: Use descriptive captions with relevant keywords
• Title Attributes: Add helpful title attributes for additional context
• Page Relevance: Match images to page topic and user intent

Visual Search Optimization

Google Lens Optimization

• High-Quality Images: Use clear, high-resolution images
• Multiple Angles: Provide different perspectives of products
• Clean Backgrounds: Use simple, uncluttered backgrounds
• Product Focus: Ensure main subject is clearly visible
• Lighting Quality: Use good lighting for clear image recognition

Shopping Visual Search

• Product Schema: Implement structured data for products
• Google Merchant Center: Submit product images to shopping feeds
• Image Quality Guidelines: Follow Google Shopping image requirements
• Variant Images: Show different colors, sizes, and angles

Structured Data for Images

Image Schema Implementation

{ "@context": "https://schema.org", "@type": "ImageObject", "contentUrl": "https://example.com/image.jpg", "description": "Detailed description of the image", "caption": "Image caption text", "creator": { "@type": "Person", "name": "Photographer Name" }, "creditText": "Photo credit information", "license": "https://creativecommons.org/licenses/by/4.0/", "copyrightHolder": { "@type": "Organization", "name": "Copyright Holder" } }

Accessibility and Image SEO

Accessibility Best Practices:

• Meaningful Alt Text: Describe image content for screen readers
