Your client wants to run on Smart Shopping campaigns and use Maximize Conversion Value as abid strategy.The client also wants to set a secondary bid strategy.Which secondary bid strategy should they select?

The most suitable secondary bid strategy for the client running Smart Shopping campaigns with Maximize Conversion Value as the primary bid strategy is Target Return On Ad Spend(tROAS).When using Maximize Conversion Value as the primary bid strategy,the focus is on optimizing bids to maximize the total conversion value obtained within the specified budget constraints. However,incorporating a secondary bid strategy like tRO AS enables the client to further refine bidding decisions based on their desired return on investment.Target RO AS allows advertisers to set a specific target for the return on ad spend they wish to achieve,there by guiding bidding decisions to prioritize the highest-value conversions that align with the set target.By leveraging tRO AS as a secondary bid strategy,the client can ensure that their bidding strategy is not solely focused on maximizing conversion value but also takes into account the desired return on ad spend,ultimately optimizing their campaign for both value and efficiency. Therefore,selecting Target RO AS as the secondary bid strategy complements the primary bid strategy of Maximize Conversion Value,allowing the client to achieve their goals of maximizing conversion value while also maintaining a specific return on investment target.
