An advertiser is launching a new Demand Gen campaign using target CPA bidding with a goal of $15 per conversion. To allow for sufficient conversion volume for AI optimization and avoid an underperforming, budget-constrained campaign, what's the minimum daily budget they should set?

For optimal performance with Target CPA bidding, Google Ads recommends a daily budget that is at least 10-15 times your target CPA. In this scenario, with a target CPA of $15, the minimum recommended daily budget would be $15 x 10 = $150. This allows the system enough budget to acquire sufficient conversion volume for its AI to learn and optimize effectively, preventing the campaign from being budget-constrained and underperforming. A budget of $75 or $15 would be too low, limiting learning and conversions. A budget of $1,500 is not the minimum required, though it would certainly provide ample budget.
