Target Return On Ad Spend(tROAS)would make a good secondary bid strategy for a client who wanted to run Smart Shopping campaigns and use Maximize Conversion Value as abid strategy.Smart Shopping campaigns are designed to automate various aspects of campaign management,including bidding,to maximize the conversion value within the given budget. By using Maximize Conversion Value as the primary bid strategy,the campaign aims to optimize for the highest possible conversion value.However,incorporating Target Return On Ad Spend(tROAS)as a secondary bid strategy provides an additional layer of control by allowing advertisers to set a specific target for the return on ad spend they wish to achieve.This bid strategy considers both the value of conversions and the cost of advertising,optimizing bidding decisions to maximize the return on investment. Therefore,combining Maximize Conversion Value with Target RO AS as a secondary bid strategy allows advertisers to balance their focus on conversion value with their desired level of return on ad spend,ensuring efficient budget allocation and maximizing overall campaign performance.
