Organic CAC
01 Definition
Organic CAC meaning: The cost to acquire customers through unpaid channels like SEO, referrals, or word of mouth.
Organic CAC divides the cost of running unpaid channels, such as content, SEO, and community work, by the customers they bring in. It is rarely zero, because staff, tools, and content all cost money even without ad spend.
Why it matters
How Organic CAC fits the work
It reveals that free channels still carry real cost, helping teams value SEO and referrals fairly against paid options.
In context
A team spent 10,000 dollars on content and SEO and won 250 organic customers, for an organic CAC of 40 dollars.
Practical note
Attribution for organic customers is hard, since many arrive through several touches. Treat organic CAC as an estimate, not a precise figure.
