Semantic Search
Semantic Search returns results by understanding intent and context, not literal keyword matches. Google BERT (2018) and MUM (2019) were the watershed. Content implication: cover complete concepts and synonyms, never keyword-stuff.

What is Semantic Search?
Semantic Search returns results by understanding intent and context, not literal keyword matches. Google BERT (2018) and MUM (2019) were the watershed. Content implication: cover complete concepts and synonyms, never keyword-stuff.
How do you apply it in practice?
Tooling: use Surfer/Frase to score 'entity coverage'; it reflects semantic relevance better than raw keyword count.
Why does it matter for AI search citations?
Generative search engines tend to extract sentences that are clearly defined, consistent and quotable on their own. Writing concepts like "Semantic Search" as one consistent definition across your site, backed by structured data and verifiable sources, lowers the chance of being misread. This improves readiness only; it does not guarantee citations or ranking gains — measure actual citations to know.

Entity Salience
Entity Salience measures how 'central' an entity is to a document, computed from frequency, position (first-paragraph weighting), and contextual co-occurrence. Google's NLP API outputs a salience score (0–1) — a core topical-relevance signal.
Search Intent
Search Intent is the real purpose behind a query. Four buckets: Informational (learn), Navigational (locate), Commercial (compare), Transactional (buy). If you mismatch intent, no amount of links will rank you.
