Site-wide N-grams

Macro-semantics (site level)
Site-wide N-grams analyze the most frequent phrases across a website, revealing dominant topics and helping assess topical coherence.

Site-wide N-grams analyze the most frequent phrases (n-grams) across an entire website, revealing its dominant topics. If 'pool' appears on 80% of pages, that's a clear topical signal for Google. N-grams are the lexical equivalent of embedding centroid — they show coherence from the perspective of words, not meanings.

Site-wide n-grams are a macro-semantics element alongside the centroid, Site Focus Score, and Site Radius, providing a complete picture of domain specialization. N-grams are especially useful for quick audits because they don't require embeddings — just simple text analysis.

In practice, check whether your site's Central Entity appears in the top 3 most frequent site-wide n-grams — if not, you have a topical coherence problem. Compare your domain's n-grams with competitors to identify missing specialist terms with high IDF.
