What two things are types of value-based Smart Bidding strategies?

The two types of value-based Smart Bidding strategies are"Maximize conversion value"and"Maximize conversion value with target RO AS."These strategies are designed to optimize bids based on the value generated from conversions rather than simply focusing on maximizing the number of conversions or targeting impression share."Maximize conversion value"aims to maximize the total conversion value within the specified budget,allowing advertisers to prioritize higher-value conversions over lower-valueones. On the other hand,"Maximize conversion value with target RO AS"focuses on achieving a specific return on ad spend(ROAS)goalby maximizing the conversion value while also considering the target RO AS metric set by the advertiser.This approach enables advertisers to optimize bids to meet their desired revenue goals while maintaining profitability targets.Incontrast,options such as"Target impression share"and"ManualCPC"are not value-based strategies;the former aims to achieve a certain level of ad visibility in search results,while the latter involves manually setting CPC bids rather than relying on automated bidding algorithms to maximize conversion value. Therefore,the selected options emphasize the importance of optimizing bids based on the value generated from conversions,aligning with the objectives of value-driven advertising campaigns and ultimately leading to more efficient use of advertising budgets and better overall campaign performance.
