marketing
The ad metric
What is CPA in marketing?
Cost per acquisition: total ad spend divided by conversions. Spend $5,000 for 100 customers and your CPA is $50. Some platforms read the A as action, meaning any tracked event rather than a customer. Deep page.

What is a good CPA?

What is Target CPA bidding?
Google's automated strategy: you set an average cost per conversion and it bids each auction to hit that average over time. Set it from account history; targets far below history throttle volume. Deep page.

UK banking
The bank-statement CPA
What is a CPA on my bank statement?
A continuous payment authority: permission a company holds to charge your card on a recurring basis. You can cancel it directly with your bank, and payments taken after cancellation must be refunded under FCA rules. Deep page.
Can my bank refuse to cancel a continuous payment authority?
No. FCA guidance is explicit: your card provider must stop the payments when you instruct it, without sending you back to the merchant first. Cancelling the payment route does not by itself end a genuine contract. Deep page.
