Hi @Seller_PikYmhmYqrbg7,

Placements of ads will be determined by whether or not you win the bid for the placement, similar to how you bid on keywords. You'll be able to see these placements when you go to adjust your bidding strategy for a campaign. You can read more about the process at the help page below:

Adjust bids by placement

Let me know if that helps answer your question!
