Semantic Clustering
Grouping content by meaning using embeddings to form coherent topic clusters.
Definition
Semantic clustering groups documents based on meaning rather than surface keywords by leveraging vector embeddings and similarity metrics. For SEO, it powers topic clustering, content gap analysis, and intelligent internal linking by identifying which pages are most related and where coverage is thin. Unlike rigid keyword groups, semantic clusters adapt to language variation and user intent, providing a robust foundation for scalable content planning.
