¿Cuánto paga un anunciante para ganar una subasta de Product Ads?

An advertiser pays the minimum amount necessary to outbid their closest competitor. This is because Product Ads uses a second-price auction model. In this system, the winning advertiser pays just enough to surpass the Ad Rank of the next most competitive bidder, rather than their maximum bid. This approach ensures that the final cost-per-click (CPC) is fair and reflects the actual competition, optimizing the advertiser's investment by preventing them from overpaying for a prominent position. The other options are incorrect because advertisers do not necessarily pay their exact initial bid or their maximum CPC, but rather the dynamically determined competitive price.
