CPA: What It Is and Why It Matters
CPA (Cost Per Acquisition) tells you how much you pay for each conversion. Lower CPA generally indicates more efficient acquisition for your budget.
CPA Formula:
CPA = Spend / Conversions
How to Interpret Your CPA:
Lower CPA: More cost‑efficient acquisition. Great for scaling.
Moderate CPA: Acceptable depending on conversion rate and AOV.
High CPA: Review audiences, creatives, placements and bidding.
Very high CPA: Likely inefficient. Optimize or reallocate budget.
