Any recommendations for account structure for brands with one category? New client I just signed sells Tumbler cups with different design variants. She does decent sales on amazon and hired me to run Google ads for her website. I'm new to e-commerce strategies and watched several of your PMax videos going over separate PMax campaign structure with best sellers/mid sellers and catch-all shopping campaigns. I have some ideas in mind for campaign structure but curious if you had a strong opinion in a situation like this. The budget is low - 3k/mo.
