It appears that the keyword bids for specific campaigns have consistently been set at the minimum bid, despite the target ACoS being below this threshold. This occurs when there are no target ACoS set at the campaign level. 

To address this issue and ensure your campaigns perform optimally, we recommend you update your target ACoS for campaigns utilizing Bids By Badger. Modifying this metric can help better align your campaigns with your specific goals and potentially improve your campaign results.

We've also implemented a change in our tool to prevent bid optimization when a user hasn't set a target ACoS.
