A rotation in a labelled slot: home banner, discovery card, category, search, or product-adjacent. Eligible campaigns share the slot over time; buying it does not mean owning it.
Position in search, trending, gems or recommendations. Promoted placement adds nothing to organic ranking, and no discovery code reads campaign data. Your analytics separate promoted from organic impressions for the same reason.
Only listed products, and only while listed. A suspension ends a campaign. Placements are always marked Promoted; asking for an unlabelled placement is not a thing we sell.
