Put your product in the places people browse on Guiru: the store home, a category, the top of search, or beside the products it competes with.
The two in-shelf slots sit between organic results, so they carry a claim the others do not: that your product belongs next to what the person is already looking at. They are gated on it. A card only renders when the catalogue already relates it to what is on screen — a semantic neighbour, a product the same people use, or at the very least the same category — and the campaign simply does not appear where it would not make sense. Nobody buys their way into a shelf about something else.
Promotions buy placement in labelled slots. They are separate from organic ranking, and separate from Guiru Pro, which buys tools and eligibility.
