Cost Per Acquisition (CPA) simply means the average cost that you pay for an acquisition. Acquisition here means your conversion.
Putting it into simple terms, every time your advertising goal is achieved, you have a conversion. Now, these goals can be – sales, leads, newsletter signup, ebook download, or any other action that you set as your advertising goals.
