Does a lower ACoS always mean more profit?

Answer · AgentXray team
A lower ACoS does not always mean more profit. ACoS, or Advertising Cost of Sales, measures the cost of ads relative to the sales attributed to them, but it doesn't account for overall profitability. For example, one seller experienced two periods with different ACoS values, where the one with a higher ACoS generated more profit daily. To accurately assess profitability, you need to consider your break-even ACoS and the profit after all ad spend, which includes sales that ads did not directly attribute. Therefore, while a lower ACoS may indicate better ad efficiency, it doesn't guarantee higher profits.
