Semantic SEO

Definition

Semantic SEO refers to the optimization of web content with the goal of conveying to search engines not just individual keywords but the full contextual meaning of a topic. Instead of focusing on isolated search terms, it considers thematic relationships, synonyms, entities, and user intent in order to build comprehensive topical authority.

Semantic SEO is the evolution of classic keyword optimization into a content-driven strategy. Search engines like Google should recognize that a page covers a topic in its full depth and provides relevant, structured answers to all of its facets.
