What is CPA?+
CPA (Cost Per Acquisition) is the total ad spend divided by the number of customers acquired. It tells you how much you're paying to win each new customer.
What is a good CPA?+
Your target CPA should be lower than your gross profit per order (or per customer if you have repeat purchase). The lower your CPA vs your gross profit, the more headroom you have to scale.
How is CPA different from CAC?+
CPA usually refers to a single-purchase / single-channel metric. CAC (Customer Acquisition Cost) is broader — it includes all marketing spend (organic, paid, content, retention) divided by net new customers.
How can I lower CPA?+
The single biggest CPA lever is creative quality and freshness. Fatigued creative drives up CPMs and crashes CTR — both push CPA up. Refresh creative every 7-14 days, test 30+ variations per product per month, and kill underperformers fast.
