The 70-20-10 rule: how Coca-Cola and Google allocate marketing budgets

Updated:

Every marketing team faces the same tension: invest in what is already working, or experiment with something new? Spend too much on proven channels and you stagnate. Spend too much on experiments and you lose the revenue that funds them. The 70-20-10 framework is a simple model for managing this tension deliberately, rather than leaving it to chance.

What is the 70-20-10 framework?

The 70-20-10 framework divides your marketing budget, time, or resources into three buckets:

The framework forces structure around innovation. You protect your core revenue while systematically exploring what comes next.

Where does 70-20-10 come from?

Several major companies adopted the 70-20-10 model independently, most notably Coca-Cola and Google.

At Coca-Cola, Jonathan Mildenhall, then Vice President of Global Advertising Strategy and Creative Excellence, championed the framework as part of the company’s Content 2020 strategy. Mildenhall talked about “liquid and linked” content — content so compelling it spreads across the web — and 70-20-10 was the investment model behind it. Seventy per cent went to low-risk proven formats, twenty per cent innovated on what was working, and ten per cent went to high-risk new ideas.

At Google, Eric Schmidt and Jonathan Rosenberg described the same ratio in their book How Google Works (2014). Google applied 70-20-10 to engineering resource allocation: seventy per cent on the core business (search and ads), twenty per cent on emerging products built on that foundation, and ten per cent on completely new ideas. Gmail and Google News both emerged from that ten per cent.

“70/20/10 became our rule for resource allocation: 70 percent of resources dedicated to the core business, 20 percent on emerging, and 10 percent on new.”

Why the 70-20-10 framework works

The framework works because it addresses the two most common failure modes in marketing resource allocation:

Failure mode 1: All core, no innovation. Teams that put one hundred per cent into proven channels feel safe in the short term but slowly lose ground. Channels saturate. Audiences shift. Competitors find new approaches. Without a deliberate allocation for experimentation, you are always reacting rather than leading. Andrew Chen describes this as the law of shitty clickthroughs — every channel declines in effectiveness over time.

Failure mode 2: Too many bets, no focus. Teams that spread resources across dozens of unproven initiatives never invest enough in any one of them to get a meaningful signal. You end up with a pile of half-tested ideas and no clear winners.

70-20-10 avoids both traps by:

How to implement 70-20-10 in your marketing

Step 1: Audit your current allocation

Before applying the framework, understand where your resources go today. Most teams are surprised to find they are spending ninety per cent or more on core activities and almost nothing on experimentation. Map your current channels, campaigns, and projects into the three buckets.

Step 2: Classify your activities

Go through your current marketing activities and categorise each one:

Step 3: Set review cycles

The real power of 70-20-10 is movement between buckets. Set a regular cadence — monthly or quarterly — to review what should graduate:

Step 4: Protect the ten per cent

The experimental budget is the first thing to get cut under pressure. Treat it as non-negotiable — it is your insurance against long-term stagnation.

Common mistakes

Treating the ratios as rigid rules. The exact split matters less than the principle. For a startup with no proven channels, a 50-30-20 split might make more sense. For a mature enterprise, 80-15-5 might be appropriate. The point is to allocate deliberately across all three categories.

Failing to graduate ideas. Some teams run experiments in the ten per cent bucket but never move winners into NEXT or NOW. The result is permanent “innovation theatre” that never impacts the core business.

Skipping the audit. If you do not know where your resources currently go, you cannot apply the framework. Start with the audit.

Cutting experiments when budgets tighten. When budgets get squeezed, the first instinct is to cut the experimental ten per cent. This is a mistake — tight times are exactly when you need to find the next efficient channel, because your existing channels are likely getting more expensive.

No learning system. The value of the ten per cent is not just the experiments that succeed — it is what you learn from every experiment, including the failures. Without a system for documenting and sharing those lessons, each experiment starts from scratch. We cover this in more detail in our guide to building a culture of experimentation.

Measuring success across the three buckets

Each bucket needs its own metrics and expectations:

BucketMetricsExpectation
NOW (70%)Revenue, ROI, CAC, conversion rateConsistent, predictable performance
NEXT (20%)Early indicators: engagement, pipeline, cost-per-lead trendsImproving trends, not yet at scale
NEW (10%)Learnings per experiment, hypothesis validation rateMost experiments will fail — measure learning velocity

The mistake most teams make is applying NOW metrics to NEW activities. If you judge experimental campaigns by the same ROI standards as your proven channels, nothing will ever graduate.

Final thoughts

The 70-20-10 framework is not a magic formula. It is a thinking tool — a way to make sure your team deliberately balances doubling down on what works with exploring what might work next. The exact ratios matter less than the discipline of allocating across all three categories and reviewing regularly.
