Is SMART-shopping / Target-ROAS better than Bidbrain?

We cannot give you a yes or no answer to these questions. SMART shopping and Target ROAS works on the incentive to sell/buy as many clicks as possible within the range of your goals. We have so far seen a positive effect on stores that are switching from SMART/target-ROAS to Bidbrain, and a negative effect while switching from Bidbrain to SMART/Target-roas. One key benefit from having BidBrain instead of SMART/Target-roas is that we don't work as a black box. You can use the data from our campaigns and apply it to your retargeting campaigns for example. You can draw conclusions and you will see what and how we are bidding.
