Signal aggregation is definitely the right mental model. We've found that tracking 'Share of Model' over time (e.g. how often a brand appears in the top 3 recommendations for a category query) is much more stable than individual prompt outputs, which can vary wildly due to temperature.
It's similar to share-of-voice in traditional PR. You can't control every mention, but you can track the aggregate trend of whether the model 'knows' you exist and considers you relevant.
