# Understanding of Traditional SEO Metrics

The article assumes the reader understands traditional marketing/SEO metrics — **Share of Search (SOS)** and **Share of Voice (SOV)** — in order to grasp how **[[concept-share-of-model-d10|Share of Model (SOM)]]** differs from and evolves beyond them.

**Why it's required:** to understand the contrast between *intent/volume* metrics (SOS reflects human search intent; SOV reflects available content volume) and the new *AI-perception* metric (SOM emulates an LLM's internal recommendation logic). Without this baseline, the significance of SOM — and the [[concept-human-ai-awareness-gap|Human-AI Awareness Gap]] between them — is easy to miss.
