How we built the list
The ranking is updated monthly and is based on data we collect from our own platform. Products that rank highly are popular with our users while also maintaining high quality according to editorial expert reviews. Specifically, we take into account how many users follow a product through price alerts or lists, how it is rated by experts and users, as well as how much traffic it generates to stores and how well it is represented in stores. No products are paid placements — the ranking is governed solely by data.
