On the AI Optimization page, click New Optimization. The form is split into steps. In step 1 (Type and account), choose between Budget Optimization or Smart Bid Cap, enter a name, select the Ad Account, and choose the campaigns, or select Entire Account (Autopilot). In step 2 (Budget), set the minimum and maximum Weekly Budget, the Monthly Budget (optional), the Daily Min and Max, and the Maximum CPA (Breakeven). In step 3 (Optimization), turn on Performance Auto-Scale and, if you want, Scale Throughout the Day. In step 4 (Distribution), set the budget percentage for each day of the week. In step 5 (Advanced), configure Horizontal Scaling, New Audiences, and how to handle ads with bad metrics. Click Create Scale to save. If you don't have any optimizations yet, the page offers ready-made templates (E-commerce Sales, Lead Gen WhatsApp, and Entire Account Autopilot) that open the form pre-filled, plus a Start from scratch button.
