What is the BuyBox on OTTO?
Last updated: 31 October 2026 · The MargenOptimierer app is in German. Button and menu names are shown exactly as you see them, with the English meaning in brackets.
Whoever has the BuyBox is the seller whose offer OTTO puts up for sale on the product page when several sellers sell the same item.
On OTTO, an item only enters the auction for Sponsored Product Ads if you have the BuyBox for it. Without the BuyBox, OTTO doesn't show the ad for this item.
Example: BuyBox for the acacia chair
Say you sell the acacia chair for 50 €, and a second seller sells it too. If OTTO puts the offer from you up for sale on the product page, you have the BuyBox and the 0.40 € bid can win an auction; if OTTO puts up the other seller's offer, the ad doesn't enter any auction.
