I currently have 2 Pmax campaigns with several asset groups inside each. One is our main ecomm category focus with asset groups for sub categories and the other is the catchall with all other website categories.
When I set this up like 2 years ago I thought that this would let me control the budget better and all that but now I am not sure. I am wondering if I should combine the asset groups and the budgets into into one of the existing Pmax campaigns to get more data and have the budget move around where needed the most? The catch all always get about double the conversions of the main focus category.
