Experienced Meta Ads Freelancer for Digital Products Shopify store

Looking for an experienced Meta Ads freelancer for a digital products ecommerce brand. We may inherit an ad account with thousands of historical purchases and are interested in leveraging existing data rather than starting from scratch. Please answer the following: 1. We have thousands of historical purchases and may inherit the previous owner’s pixel and ad account. How would you leverage that data, and would you continue using the existing pixel? 2. How would you structure campaigns for a brand with multiple digital products? 3. How much emphasis do you place on creative testing versus audience targeting, and what does your testing process look like? 4. What would your first 30 days look like if you took over the account? 5. How do you decide when to kill, iterate, or scale an ad? Please include examples of ecommerce brands you’ve managed and approximate monthly ad spend.
