Semantic HTML

HTML markup that uses meaningful tags to describe the structure and content of a webpage, helping AI systems understand context.

Understanding Semantic HTML

Semantic HTML uses elements like <article>, <nav>, <header>, <main>, and <aside> to provide meaning to content structure. For AI systems, semantic HTML creates a clear hierarchy and context that improves content comprehension. Proper heading structure (H1-H6), lists, and semantic elements help LLMs parse and understand your content more accurately.
