When CPA Is Too High
A high CPA does not automatically mean traffic is expensive.
Often, the real issue is conversion efficiency.
Think about CPA as a simple equation:
CPA = Cost ÷ Conversions
This means CPA can increase because:
- costs rise
- conversions decrease
- both happen simultaneously
To diagnose the problem, review both sides of the equation.
If Costs Increased
Investigate:
- CPC trends
- audience competition
- bid strategy
- targeting scope
If Conversions Declined
Investigate:
- landing page experience
- offer competitiveness
- website performance
- conversion tracking
This distinction is critical because the solution depends entirely on the cause.
