Media Buying

Media buying is the operational discipline of translating an advertising strategy into actual inventory purchases. It spans the entire process from planning channel allocation and negotiating rates to executing campaigns and optimizing performance in real time. Modern media buying is predominantly programmatic, but direct deals with publishers still play a role for premium inventory access.

For growth teams, media buying efficiency directly determines customer acquisition cost and scalability. AI has automated much of the tactical execution, with algorithms handling bid management, budget pacing, and placement selection. This shifts the media buyer's role toward strategic decisions: which channels deserve investment, how to structure campaigns for algorithm learning, and when to intervene in automated systems. Growth engineers support media buying by building the data infrastructure that enables smart allocation, including attribution models that reveal true channel value, forecasting systems that predict inventory costs, and experimentation frameworks that measure incrementality. The most effective growth organizations integrate media buying deeply with product and engineering rather than treating it as a siloed marketing function.
