Strategies to improve customer acquisition efficiency:

Aim for a 3:1 ratio or higher. If your LTV is lower than 3x CAC, you need to either increase customer value or reduce acquisition costs.

Track CAC by channel and double down on channels with the lowest CAC and highest conversion rates. Cut or optimize underperforming channels.

Better website UX, clearer value propositions, and streamlined signup flows can significantly reduce CAC by converting more visitors into customers.

Referral programs typically have much lower CAC than paid channels. Incentivize existing customers to bring in new ones.
