What is CAC in channels?

CAC (Customer Acquisition Cost) by channels is a metric that reflects the average cost of acquiring a single customer through a specific marketing channel.

For example, if 100,000 rubles are spent on social media advertising and 500 customers are attracted, then the CAC for this channel will be 200 rubles.

Analyzing CAC by channels helps understand the effectiveness of each channel, optimize the budget, and focus on the most profitable ways to attract users.
