Media Buying

The process of purchasing advertising space and time across channels.

Definition

Media buying is the process of negotiating and purchasing ad inventory across advertising channels — from social platforms to programmatic networks to direct publisher deals. A media buyer's job is to get the best possible placements at the lowest possible price while maximizing campaign performance.

Types of Media Buying

  • Self-serve: Buying directly through platform dashboards (Meta Ads Manager, Google Ads)
  • Programmatic: Automated buying through DSPs
  • Direct: Negotiating directly with publishers for premium placements

Key Skills

Successful media buying requires understanding auction dynamics, bid strategies, audience targeting, budget pacing, and performance optimization.

Examples

  • A media buyer allocating 60% to Meta, 25% to Google, and 15% to TikTok based on historical ROAS
  • Negotiating a direct sponsorship deal with a niche publisher at a fixed CPM

Common Mistakes

  • Not diversifying spend across channels — over-reliance on a single platform creates risk
  • Making too many changes too quickly without giving campaigns time to optimize
