Heading Hierarchy (H1-H6)

html

<!-- CORRECT: Logical hierarchy -->
<h1>Main Page Title</h1>  <!-- Only one H1 per page -->
<h2>Major Section</h2>
<h3>Subsection</h3>
<h3>Another Subsection</h3>
<h2>Another Major Section</h2>

<!-- INCORRECT: Skipping levels -->
<h1>Main Title</h1>
<h3>Skipped H2</h3>  <!-- BAD: Skipped H2 -->
<h4>Subsection</h4>
<h2>Back to H2</h2>  <!-- BAD: Wrong order -->

Image SEO

html

<!-- Good image SEO -->
<img src="product-blue-dress.jpg" 
     alt="Blue summer dress with floral pattern for women"
     width="600"
     height="400"
     loading="lazy"
     srcset="product-blue-dress-300w.jpg 300w,
             product-blue-dress-600w.jpg 600w,

Link SEO

html

<!-- Good link text -->
<a href="/html-seo-guide">HTML SEO Best Practices Guide</a>  <!-- Descriptive -->
<a href="/contact">Contact our SEO experts</a>  <!-- Action-oriented -->
