Paid Advertisements CAC: Advert spend ÷ prospects acquired by way of adverts
Content material CAC: Content material prices ÷ attributed conversions
Companion CAC: Partnership charges ÷ referred prospects
This siloed method ignores the truth of recent buyer journeys. A buyer may uncover your model by way of content material, analysis on social media, and eventually convert by way of a paid advert.

What different data may very well be left unconsidered, like, “Which channel will get credit score?” or, “How do you account for model advertising and marketing that helps all channels?”.
