The budget allocation problem
How you allocate your marketing budget is one of the most consequential decisions you make as a marketing leader. Too much in brand, and you have awareness without conversion. Too much in performance, and you're buying leads with no lasting equity. And a budget concentrated in a single channel is exposed to algorithm changes, platform cost increases, or audience fatigue.
Most marketing budget allocation decisions are made on the basis of what worked last year, what the team knows how to do, and what the loudest stakeholders advocate for. A principled framework for maximising return across the portfolio rarely comes into it.
The 70-20-10 rule as a starting framework
The 70-20-10 budget framework (allocate 70% to proven channels and tactics, 20% to emerging or less-tested approaches, and 10% to experimental initiatives) provides a useful starting structure for budget allocation. It institutionalises experimentation while protecting the majority of spend on initiatives with established return.
70-20-10, as a starting point rather than an answer
In practice, the right split depends heavily on business stage and market maturity. An early-stage business with limited brand awareness should weight more heavily towards brand-building; a mature business with strong brand equity should weight more towards conversion-focused performance marketing.
Channel allocation: the sequencing logic
The most common mistake in channel allocation is spreading budget too thin across too many channels before any single channel has been optimised to its potential. A single channel run well at appropriate scale almost always outperforms five channels run under-resourced.
Magic Pulpo recommends a sequencing approach: establish and optimise one primary acquisition channel to consistent positive ROI before adding a second. For most B2B businesses, this typically means starting with either content and SEO (for sustainable long-term acquisition) or paid search (for immediate, measurable lead generation), proving the economics, and then expanding to additional channels.
Measuring return across the portfolio
The fundamental challenge in marketing attribution is that different channels operate at different points in the funnel and on different time horizons. Brand and content investments generate returns over 6-24 months; paid search generates returns within days. Comparing them on the same short-term ROI metric systematically undervalues long-term brand investment.
Use a portfolio measurement approach: track short-term efficiency metrics (CPA, ROAS) for performance channels, and brand health metrics (aided awareness, consideration, NPS) for brand channels. Review the combined picture quarterly.
