Definition

Semantic HTML is the use of HTML elements that convey meaning about the structure and content of a page — using elements like article, section, header, nav, main, and aside rather than generic div and span containers. Semantic HTML aids both accessibility and machine understanding. Semantic HTML is the document structure layer of AI SEO. AI crawlers use semantic HTML elements to understand content hierarchy: what is the main content, what is the header, what is the article body, what is supplementary navigation. Pages built with semantic HTML give AI systems a reliable structural map that improves extraction accuracy. A page where all content sits in undifferentiated divs requires significantly more inference to parse correctly.
