          srcset="hero-large.avif 1200w, hero-large.webp 1200w" 
          type="image/avif, image/webp">
  
  <!-- Medium screens -->
  <source media="(min-width: 768px)" 
          srcset="hero-medium.avif 800w, hero-medium.webp 800w" 
          type="image/avif, image/webp">
  
  <!-- Mobile fallback -->
  <source srcset="hero-small.avif 400w, hero-small.webp 400w" 
          type="image/avif, image/webp">
  
  <!-- Universal fallback -->
  <img src="hero-large.jpg" 
       alt="SEO optimized hero image description"
       width="1200" 
       height="600"

SEO-Friendly File Naming

File Naming Best Practices:

✅ Good Examples:

• seo-optimization-guide-2025.webp
• mobile-seo-checklist-infographic.jpg
• content-marketing-strategy-diagram.png
• keyword-research-tools-comparison.webp
• technical-seo-audit-process.jpg

❌ Poor Examples:

• IMG_12345.jpg
• Screenshot_2025_01_07.png
• untitled-1.webp
• image-copy-final-v2.jpg
• DSC00456.JPG

File Naming Strategy Framework:

Naming Convention Formula:

[primary-keyword]-[secondary-keyword]-[descriptor].[extension]

• Use hyphens (-) to separate words

• Include primary target keyword

• Keep under 100 characters total

• Use lowercase letters consistently

• Avoid special characters and spaces

• Include descriptive context when possible

Alt Text Optimization Mastery

Alt text serves dual purposes: improving accessibility for screen readers and providing context for search engines to understand image content.

Alt Text Writing Guidelines

Effective Alt Text Formula:

Structure: [Primary Object] + [Action/Context] + [Keywords] + [Additional Details]

Example 1 (Product):

"Professional woman using laptop for SEO keyword research in modern office workspace"

Example 2 (Infographic):

"Mobile SEO optimization checklist infographic showing 15 essential ranking factors for 2025"

Example 3 (Chart):

"Bar chart comparing organic traffic growth between traditional SEO and AI-powered optimization strategies"

Alt Text Optimization Rules:

✅ Best Practices:

• Keep between 10-125 characters
• Include primary keyword naturally
• Describe the image content accurately
• Consider the surrounding context
• Use specific, descriptive language
• Avoid "image of" or "picture of" phrases

❌ Avoid These Mistakes:

• Keyword stuffing with unnatural phrases
• Overly generic descriptions
• Leaving alt text completely empty
• Copying the image file name exactly
• Using only keywords without context
• Describing obvious UI elements

Context-Specific Alt Text Strategies

Product Images

Focus on:

• Product name and brand
• Key features and benefits
• Color, size, material
• Use case or application
• Model numbers when relevant

Infographics

Include:

• Main topic and purpose
• Key data points or statistics
• Number of steps or sections
• Target audience context
• Year or timeframe when relevant

Decorative Images

Approach:

• Use empty alt="" for pure decoration
• Describe mood or atmosphere if relevant
• Connect to content theme
• Consider brand and style elements
• Focus on emotional context

Image Schema Markup and Structured Data

Image schema markup provides search engines with additional context about your images, improving their chances of appearing in rich results and image search.
