Pro Tips for Customer Acquisition Cost
- Compare CAC against customer lifetime value (LTV) — a healthy business generally wants LTV several times higher than CAC.
- Track CAC by channel to see which marketing efforts are most cost-effective at acquiring customers.
Common Customer Acquisition Cost Mistakes to Avoid
- Looking at CAC in isolation without comparing it to customer lifetime value, since a low CAC means little if those customers don't generate enough revenue to justify it.
