(B) Enhanced CPC
(C) Target CPA
(D) Maximize Clicks
(E) Maximize Conversions
Target CPA and Maximize Conversions bid strategies require you to set up conversion tracking using UET tags in order to avoid unprofitable clicks and maximize conversions. In both bidding strategies, you don’t need to set bids for ad groups or keywords because Microsoft Advertising will do that for you. You just have to provide your budget and Microsoft Advertising will try to get you maximum conversions within that budget.
