You may be right, you may be not - the essence from my point of view is not to trust any such information about rankings
Exactly this. Consider that Thomann is paying somebody to take care of its "rankings", it is a cost that must generate a corresponding profit to justify it. Why should a retailer publish detailed information about its sales? It goes against every basic principle of marketing. They are a profit organization, everything they do must push sales and produce revenue, of course they won't publish sales data just for the sake of transparency.
There are so many reason NOT to do it, just a couple I can think of (and there are surely many more):
- sharing confidential business data with the public, that can be seen and used by competitors, hackers, tax agencies etc.
- of course the "top" products will be featured extensively at the top of the rankings, which in itself is a form of advertising. So the best-selling products will be pushed even more, while the products at the bottom of the list will be lost and forgotten. This makes little sense: a retailer wants to push the low-selling items, while the big sellers are already successful by themselves.
So, why are they doing it? Because it's a marketing tool. It's probably a kind of weighted average between the number of units sold and the individual cost of the units, and then reshuffled according to marketing needs. They will use it to give more prominence to the right product at the right time, pushing low-selling items, promoting end-of-stock products to clear inventory, etc. For example, lately the Moog One was always at the top (or very near the top) of the "Synth" category. I will NEVER believe that people are buying an ELEVEN-THOUSAND-EURO SYNTH more than any other cheap product from Yamaha, Korg, Roland or Behringer.
