Marketplace research · original data
We measure the shelf.
Then we publish it.
Every study here runs on our own page-one tracking corpus, and every one ships with its methodology, its caveats, and its nulls. Correlational findings are labeled correlational. Knowing what does not matter is as actionable as knowing what does.
