Shelf position used to be physical. In AI search it is share of voice: how often the assistant names you when a buyer asks, compared with everyone else.
- Share of voice is how often AI names you versus rivals, the new shelf position.
- It moves before sales do, so it is an early signal.
- Grow it by being the clearest, most trusted answer, and track it monthly.
