How to Improve

Build a referral engine that turns every customer into an acquisition channel. Invest in bottom-of-funnel content that captures high-intent search traffic. Track blended CAC weekly and set alerts when it exceeds 2x your target.

Ehsan's Analysis

Every E-commerce company I have advised at Growth stage that broke into top-quartile on this metric did one thing differently: they built internal tooling to track it in real-time instead of relying on monthly reports. The latency between signal and action is where value leaks. Build a dashboard that your team checks before their morning coffee.
