For a fashion store, after how many conversions do you recommend that a product should have (or how much spend) before it should be added into the pmax
I feel i've been adding products into the scaling pmax campaign too early - some products begin to perform worse - maybe due to weak data signals after I add them into the pmax scaling
Are you able to put a physical number on it if you had to - or maybe a minimum number for number of purchases or amount spent
