Glossary entry
What is CPA (Cost Per Acquisition)?
CPA is the cost to acquire one paying customer or qualified lead. It's the most honest performance metric in paid media because it ties spend directly to business outcomes. Healthy CPA equals roughly one third of customer LTV in most verticals.
CPA vs. CPL
CPA usually means cost per paying customer. CPL is cost per lead (form fill, sign-up). Lead-to-customer conversion is rarely 100%, so CPL must be multiplied by your lead quality rate to compare to CPA.
How to lower CPA
Three levers: (1) higher conversion rate (better landing page, faster checkout), (2) lower CPC (better Quality Score, stronger creative), (3) better targeting (cleaner audiences, smarter exclusions). All three compound.
Target CPA bidding
Smart Bidding strategies like Target CPA tell Google or Meta what you're willing to pay per acquisition, and the algorithm bids accordingly. They need 30+ conversions per month per campaign to work well.

Frequently asked
How is CPA different from CAC?
CPA usually counts paid-channel acquisitions only. CAC is fully loaded across all channels and includes salaries, tools, and overhead.
What's a healthy CPA?
About one third of LTV. So if customers spend $300 over their lifetime, target CPA under $100.
Can I bid to CPA from day one?
Smart Bidding needs conversion data first - usually 30 conversions in 30 days. Start with manual or eCPC, then graduate to Target CPA.
Why is CPA rising?
Auction pressure, audience saturation, creative fatigue, or a checkout regression. Audit conversion rate before blaming traffic.
