What's the difference between a media plan and a media buy?

A media plan is the strategic document that specifies what advertising to run — channels, audiences, budgets, timing, and formats. A media buy is the act of purchasing that advertising — negotiating rates with publishers, setting up deals in platforms, or bidding programmatically. In many organizations, the same team handles both, but in larger organizations media strategy (the plan) and media execution (the buy) are separate disciplines.

What format should a media plan be in?

The best format is one that maps directly to how the plan will be executed. Spreadsheets are flexible but require manual translation into DSP structures. Structured templates that encode standard fields (channel, format, targeting type, bid strategy) reduce translation errors. The ideal is a planning format that can be directly imported into your trafficking system.

How far in advance should a media plan be finalized?

For programmatic campaigns, plans should be finalized at least 5–7 business days before launch to allow time for trafficking, QA, and creative review. For high-complexity campaigns with many line items, custom targeting, or new creative formats, allow 2–3 weeks. Campaigns launched under extreme time pressure are significantly more likely to contain errors.

How do you handle media plan changes after campaign launch?

Change requests should go through the same approval process as the original plan. The requested change is documented, reviewed, approved, and implemented — with an audit trail at each step. 'Informal' changes made directly in the platform without a corresponding plan update create discrepancies between what was approved and what's actually running.

What's the role of media planning in programmatic vs. direct buys?

In programmatic buying, the media plan informs the DSP setup — targeting parameters, bid strategies, budget allocations, and flight dates are configured based on the plan. In direct deals, the media plan also specifies the specific publisher, placement, format, and negotiated rate — which then needs to be reflected in the deal ID setup within the DSP.

Media Planning Best Practices for Advertising Operations Teams

Media planning sits at the intersection of strategy and operations. A plan that's brilliant in a spreadsheet but ungovernable in execution creates more problems than it solves. This guide covers the planning frameworks, data practices, and operational systems that connect strategy to execution.
