Before we explain it to you, we need to discuss what the concept of semantics is first. Basically, it involves words, their relationships, and what those relationships entail in certain contexts. This certainly is ideal for Google. Remember, a search engine’s major purpose is to curate the most relevant results for a user’s query. Semantic search, therefore, is the way a search engine uses data to identify the context, meaning, and intent needed to deliver the most accurate results.
