Budget Allocation Frameworks
3 min read
Marketing budget allocation is a deployment problem, not a spending problem. Every dollar has a mission. The 70/20/10 framework provides the operational structure: 70% goes to proven channels — the tactics you know work because you have the data to prove it. 20% goes to emerging channels — tactics with early positive signals that need more investment to validate. 10% goes to experimental channels — bets on unproven ideas that could become the next 70% allocation. This is not a suggestion. It is a discipline that prevents the two budget failure modes: over-concentration on one channel and over-diversification across too many.
The 70% allocation requires ruthless honesty. "Proven" does not mean "we have always done it." Proven means you have attribution data showing this channel produces pipeline at an acceptable cost. If your trade show budget is in the 70% category but you cannot show pipeline attribution, it belongs in the 20% category until you can. The 20% allocation is your testing ground — channels get promoted to 70% when the data supports it, or demoted to 10% when it does not. The 10% is your insurance against disruption — if you are not experimenting, you are not learning, and the competitor who is experimenting will find the next channel before you do.
- Audit Current Allocation Map every dollar to a channel and categorize as proven (70%), emerging (20%), or experimental (10%). Most organizations discover they are spending 90% on "proven" channels with no data proving they work and 0% on experiments. The audit reveals the truth.
- Set Promotion Criteria Define what a channel needs to demonstrate to move from 10% to 20% (early positive signals) and from 20% to 70% (consistent pipeline attribution at target CAC). Without criteria, promotion decisions are political instead of data-driven.
- Quarterly Rebalance Every quarter, move budget based on performance data. Kill experiments that showed nothing. Promote emerging channels that are producing. Redirect proven channel budget if performance is declining. The framework only works if you actually rebalance.
