An advertiser is interested in generating conversions through Google Display ads, but they're relying on the campaign's help to set bids. Which two bidding strategies used in Display campaigns can they choose from to automatically set their bids? Choose two.

Target ROAS and Target CPA are both Smart Bidding strategies designed to automatically optimize bids for conversions. Target ROAS aims to achieve a specific return on ad spend, while Target CPA focuses on getting as many conversions as possible within a target cost per acquisition. Both strategies automate bid adjustments to meet these conversion-focused goals. Enhanced CPC (ECPC) is a semi-automated strategy that adjusts manual bids up or down, but it doesn't fully automate bidding like Target ROAS or Target CPA. Cost per engagement is a bidding strategy for video campaigns, not typically used for conversion-focused Display campaigns.
