Semantic SEO

Semantic SEO is an approach to website optimization based on assigning meaning to the entire site structure rather than optimizing for individual keywords.

It's built on the EAV model, attribute hierarchy (UNIQUE/ROOT/RARE), macrosemantics (Site Focus Score, centroid) and microsemantics (SRL, Information Density, Cost of Retrieval). The key principle states: 'Not the quantity of keywords, but the quality of topic coverage determines ranking.'

This represents a paradigmatic shift — from phrases to entities, from keyword density to Entity Salience. In keyword SEO, 'car', 'passenger car', and 'electric car' are three phrases; in semantic SEO, they're one entity with attributes.

In practice, semantic SEO requires a mindset change — instead of building keyword lists, create an EAV entity model, classify attributes as UNIQUE/ROOT/RARE, and develop a topical map with CORE and OUTER sections. Semantic SEO is the foundation of semantic optimization.
