Customer Acquisition Cost (CAC): Semrush vs Hadrian
DIRECT ANSWER

It is a primary efficiency metric for growth teams, typically evaluated alongside LTV to determine whether customer economics are sustainable. Semrush addresses customer acquisition cost (cac) as a tool you prompt manually; Hadrian's agents execute it continuously on your live brand data under your approval gate.
What customer acquisition cost (cac) means in practice
The standard CAC formula is: total sales and marketing spend ÷ number of new customers acquired, measured over the same time period (monthly or quarterly). Fully-loaded CAC includes salaries and benefits for sales and marketing staff, agency and contractor fees, ad spend, tool and software costs, and event costs — not just media spend. Blended CAC mixes all channels; paid CAC isolates spend on paid acquisition only. Both are useful; the distinction matters when evaluating channel efficiency.
