You only have 3 levers for smart shopping: SKU, bid strategy and budget. The big thing to be careful of is smart shopping can degrade in performance over time and need someone to fix/change things. Most of our clients have a mix of smart and standard shopping campaigns running. You can put all your ad spend into smart shopping, but just becareful that you don’t see a massive dip in performance months from.

One last point, smart shopping will always do better than standard shopping. The reason for this is smart shopping including remarketing audiences automatically. That alone will make performance appear better out from the gate.
