The enhanced cost-per-click (ECPC) bidding strategy can be described in which of the following ways?

Enhanced CPC (ECPC) is a Smart Bidding strategy that helps you get more conversions by automatically adjusting your manual bids. It works by analyzing various real-time signals at auction time, such as device, location, time of day, and other factors, to predict the likelihood of a conversion. If ECPC predicts a conversion is more likely, it will slightly raise your maximum CPC bid (up to a certain percentage, typically 30%) to help you win that auction. Conversely, if a conversion is less likely, it will lower your bid. The options suggesting ECPC lowers a bid before looking at auctions are incorrect because ECPC's primary function is to optimize for conversions, which often involves raising bids for high-potential auctions. Options mentioning "target return on investment (ROI)" are incorrect as that concept is more aligned with target ROAS (Return On Ad Spend) bidding, not ECPC.
