“智能点击付费”(ECPC) 出价策略是如何运作的？

Enhanced Cost Per Click (ECPC) is a Smart Bidding strategy that optimizes your bids in real-time auctions to help you get more conversions. It works by automatically adjusting your manual bids up or down based on the likelihood of a conversion. If ECPC predicts a click is likely to lead to a conversion, it will increase your maximum CPC bid (up to a certain limit) to help you win that auction. Conversely, if a click is less likely to convert, it will decrease your bid. This dynamic adjustment based on auction-time signals is why the correct answer states ECPC considers auction conditions and raises the maximum CPC bid. The incorrect options either suggest lowering bids when conversions are likely or incorrectly link ECPC to Target ROAS, which is a different bidding strategy.
