Common Mistakes

1. Optimizing Only for Trials

Trials that don't convert waste CAC. Optimize for trial-to-paid, not just trials.

2. Ignoring Post-Acquisition

The ad relationship shouldn't end at signup. Retention advertising matters.

3. Wrong LTV Assumptions

Using inflated LTV leads to overspending on CAC. Be conservative.

4. Channel Silo Thinking

A customer's journey spans channels. Measure holistically.

5. Neglecting Expansion

Existing customers are your best upsell opportunity. Advertise to them.
