Semantic HTML
Semantic HTML uses HTML5 elements with meaning: <article>, <section>, <nav>, <header>, <footer>, <aside>, <main>, <figure>. Unlike <div>/<span> which carry no meaning, semantic tags help machines understand content structure.
⚡Why It Matters
AI search engines rely on semantic HTML to understand page structure and accurately extract main content. Pages using semantic HTML have 30-50% higher citability scores.
