4. Your customers need to repurchase

5. Measurement that doesn't deceive you

- attribution tool that looks at all channels together;
- Overall return (turnover ÷ advertising) and contribution margin from real orders, not just what every platform says about itself.

Mistakes that cost money
- You double the budget in one day. It increased gradually and look at the profit in 7, 14 and 28 days.
- You judge only by ROAS. A ROAS of 4 with a low margin can be a disaster.
- «You cut the audience into dozens of ad sets. In 2026, that confuses AI.
- You are leaving AI Max without control. You pay for irrelevant searches.
- You forget about the middle order. +5 € on 10,000 orders is +50,000 € per month.
