Question 1

What is cost per acquisition (CPA)?

Accepted Answer

Cost per acquisition is the amount you spend on advertising to get one new customer, lead, or conversion. It is calculated by dividing total ad spend by the number of conversions. A CPA of $25 means each new customer cost you $25 in ad spend.

Question 2

What is a good CPA?

Accepted Answer

A good CPA depends on your product price and profit margins. If your average order is $100 with a 50% margin, a CPA under $50 is profitable. E-commerce CPAs typically range from $10 to $45, while B2B services see $50 to $200. Compare your CPA to your profit per customer, not to industry averages alone.

Question 3

What is the difference between CPA and CPC?

Accepted Answer

CPC (cost per click) is what you pay each time someone clicks your ad. CPA (cost per acquisition) is what you pay when someone completes a conversion, like a purchase or sign-up. CPA accounts for your conversion rate, making it a more complete measure of advertising efficiency.

Question 4

How do I lower my CPA?

Accepted Answer

Improve your landing page conversion rate, refine audience targeting, test new ad creative, use retargeting campaigns, and optimize for the right conversion event in your ad platform. Even small conversion rate improvements can cut CPA significantly.
