Embeddings Vector Embeddings & Semantic Search Meaning as coordinates.

A vector embedding is a numerical representation of meaning — a sentence, paragraph, or document mapped to a point in high-dimensional space. Semantic search uses embeddings to find passages that mean the same thing as a query, even with no shared keywords. Every modern AI search product (Perplexity, ChatGPT Search, AI Overviews) leans on embeddings to retrieve.

How Embeddings differs from RAG, GEO, LLMO

Keyword search matches strings. Semantic search matches meaning — embeddings let "how do I lower my heart rate" retrieve a paragraph titled "reducing resting pulse" even with zero shared words.

How Mentionwell handles Embeddings

  • Per-article embeddings indexed for semantic retrieval inside RAG-style pipelines.
  • Embedding similarity drives internal linking — related articles surface each other automatically.
  • Markdown mirrors so retrieved chunks are clean text rather than HTML.

Frequently asked questions about Embeddings

What is a vector embedding?

A numerical representation of meaning — text mapped to a point in high-dimensional space, where semantically similar text lives close together.

Why do embeddings matter for AI SEO?

Every AI search product uses embeddings to retrieve passages relevant to a query. Pages that embed cleanly (clear topic, dense meaning, clean Markdown) retrieve more often.
