Merchant center-based dynamic remarketing ad

[하진호]

Hi.

I am going to execute dynamic remarketing through shopping ad. We will proceed using merchant center.

question
1. Does it automatically become dynamic remarketing when you create a shopping ad?
2. Do I have to set up a userlist to proceed with dynamic remarketing?
3. Should I only use DISPLAY instead of SHOPPING?
