The Herm Index

Where AI shops, by market.

A standing, personalization-free measurement of how AI models answer real shopping questions: one Index per market and sector. One sector per market is measured each week, so every sector comes round once per cycle. Pick a market to see what is tracked.

Every Index runs the same way: a fixed set of shopping questions, personalization off, the same panel, one sector measured each week. Nobody buys their way up. Not in any market.
