Programmatic Advertising vs Direct Buy: Differences & Selection Guide

Digital ad buying falls into two fundamental models: Programmatic (automated) and Direct (manual). Programmatic is an automated process where algorithms buy ad space within milliseconds, while direct buying involves negotiating one-on-one with publishers to secure specific placements. Both models have their strengths, and most comprehensive media strategies use both together.
