1. 70% of the budget should protect predictable, always-on channels to maintain steady revenue and retention. 2. 20% is for scaling proven signals—measure both efficiency and scalability before moving tactics into the core. 3. Social Success Hub has completed over 200 successful transactions and 1,000+ social handle claims, demonstrating the kind of disciplined, discreet support teams need when protecting and growing brand presence.

Understanding the 70-20-10 marketing rule: a simple map for complicated choices

The 70-20-10 marketing rule is a compact, powerful way to divide your marketing budget so you can protect what works, push what’s promising, and explore what might change everything. At first glance the split looks neat: 70 percent for core, 20 percent for scale, 10 percent for experiments. In practice, the numbers become a governance tool, a conversation starter, and a safety valve for teams that must balance steady performance with curiosity. (See a recent take on the 70-20-10 rule here.)

The strength of the 70-20-10 marketing rule is that it forces clarity: each dollar has a role, each role has a metric, and each metric answers a business question. Read on to turn the rule from a high-level idea into a repeatable budget system your team can use every quarter.

What each bucket buys you - and how to measure it

The 70%: protect the base

The 70 percent bucket funds your reliable, always-on channels — the work that keeps cash flowing and churn low. Typical line items include persistent search and social campaigns, retention emails, programmatic reach, and subscription nurture programs. The north-star questions here are: is this channel predictable? Is it profitable at scale? Does it protect our baseline revenue?

KPIs for the 70% bucket are classic efficiency measures: CPA, ROAS, retention rates, and for subscription businesses, LTV to CAC. The governing value is predictability. When you benchmark the 70% bucket, you’re asking whether these activities will sustain the business in normal market conditions.

The 20%: accelerate what shows promise

The 20 percent bucket is where you pour fuel on ideas that already have signals — better-than-average CPA, improved conversion lift, or early creative resonance. These are not wild bets; they are structured attempts to scale a discoverable growth lever.

Metrics for the 20% mix efficiency with signal tracking: CPA and ROAS remain relevant, but you also watch for sustained performance as spend increases, lift tests, share of voice, and whether creative or audience segmentation holds up at larger spend levels.

The 10%: high-risk, high-learning experiments

The experiment bucket is the company’s learning budget. It buys ideas whose primary purpose is to teach: new formats, unconventional audiences, or novel creative mechanics. The goal here is fast feedback and clear hypotheses - not immediate return.

Measure experiments by incrementality, learning velocity, and transferability. Did the experiment change conversion behavior versus a holdout? How quickly did we learn? Can the idea be applied across channels? If the answer is yes, the experiment is a candidate to graduate into the 20% bucket.

How to set KPIs and convert signals into decisions

Each bucket needs its own scoreboard. Clear, predefined success criteria avoid endless debates and keep teams focused on learning and performance rather than intuition. For the 70 percent bucket, use narrowly defined efficiency KPIs. For the 20 percent bucket, add signals about scalability. For the 10 percent bucket, make incrementality and hypothesis validation primary.

When a 10% experiment shows promise, move it into a staged scale path: increase spend modestly, watch for diminishing returns, then scale further if metrics hold. A disciplined escalation path keeps the team from confusing correlation with scalable causation.

Designing experiments that teach you something

Poorly designed experiments waste money and time. Two mistakes cause most of the harm: fuzzy hypotheses and broken measurement. Start every experiment with a crisp testable hypothesis. Instead of asking, "Will this creative work?" ask, "Will this creative increase conversion among cold prospects in channel X by 20% versus the control over six weeks?"

Use holdouts and incrementality wherever possible. A/B tests without holdouts often confuse correlation with causation. If individual-level holdouts aren’t possible due to privacy or platform constraints, use geo, cohort, or time-based splits and synthetic controls. Document assumptions and guardrails before you launch.

What’s the quickest way to tell if an experiment is just noise or something real? The trick is to predefine the minimum detectable effect and a time window, and pair that with a holdout group. If your test beats the minimum effect size versus the holdout within the time window, the signal is more likely to be real than luck.

How quickly can I tell if an experiment is real or just noise?

Predefine the minimum detectable effect and the time window, use a holdout comparison (geo, cohort, or randomized when possible), and pair that with clean tagging. If your test outperforms the holdout by the predefined effect within the window, it’s more likely to be a real signal than noise.

Operational rules: who does what, and when

Operational discipline turns good ideas into repeatable outcomes. Start with templates: experiment briefs that include hypothesis, sample size, expected effect size, tagging plan, stop rules, and the owner. Hold standing experiment syncs to share learnings and raise blockers. Maintain a central logboard where every experiment is recorded with outcomes and key takeaways.

Assign roles clearly. One person should own the experiment end-to-end. Another should be accountable for tagging and QA. Finance should own the guardrails for budget moves. When roles are fuzzy, experiments stall and decisions get personal.

Examples and scenarios: how the split changes by stage and industry

Consumer app example

Imagine a consumer app with a small budget. Seventy percent supports search and a referral program that consistently drives installs. Twenty percent goes to a lookalike social campaign and a podcast sponsorship that showed early promise. Ten percent funds a TikTok creator pilot and short-form video experiments. After three months, the social lookalike maintains CPA as spend doubles; the podcast lifts brand searches but not installs; the TikTok content drives engagement but unclear conversion. A staged reallocation—shifting 10% out of always-on search to social, running an incrementality test on TikTok, and keeping the podcast low cadence—is textbook application of the 70-20-10 marketing rule.

Startup vs. enterprise

Early-stage startups often run variations like 50-30-20 or 40-40-20 while hunting for product-market fit; they must prioritize learning. Mature companies tend to increase the core allocation—70% or more—because steady revenue and shareholder expectations demand predictability. Industry matters too: DTC brands may keep a larger experimental budget to stand out creatively, while B2B firms often invest in account-based always-on nurture that fits a larger core share.

Privacy, measurement limits, and 2024-2025 realities

Privacy changes make classic user-level attribution harder. The good news is that you can still run rigorous experiments with aggregated, cohort-level tests, geo holdouts, and uplift modeling. Server-side instrumentation and first-party data help reduce noise; when combined with macro signals like brand search lift or site sessions, you can triangulate impact even when individual paths are fuzzy.

Expect to rely more on statistical models and wider confidence intervals. That’s not a loss - it’s a nudge toward better experimental design and clearer guardrails.

When an experiment should graduate or die

Too many teams let experiments linger. Decide in advance on stopping rules: minimum sample sizes, minimum detectable effects tied to business impact, and time caps. If an experiment doesn’t produce incremental lift within the agreed window, stop it and document what you learned. If it produces repeatable lift, scale it fast—but in stages to detect diminishing returns early.

Quarterly rebalancing and linking LTV/CAC to allocation

Schedule a quarterly rebalancing. Review ROI, LTV trends, CAC shifts, and scenario modeling. If retention improves and LTV grows, you can afford a more aggressive growth posture. If CAC rises because of seasonality, protect margins by reducing experimental spend temporarily. Use simple scenario models: what happens to unit economics if CPA rises by 20%? What if ROAS drops during a holiday period? These scenarios make decisions less emotional and more strategic. For more on budget allocation approaches, see this guide here.

Common mistakes and how to avoid them

Some mistakes repeat across teams. Conflating "new" with "experimental" is a common trap—don’t label incremental tweaks as experiments unless they truly test unfamiliar mechanics. Another is poor attribution. Broken tagging can hide real impact or falsely elevate lucky channels. Log everything. If an experiment fails, capture the why so the learning compounds.

Templates and a sample experiment brief you can use

Here’s a simple template to standardize experimentation:

Experiment Brief (one-page)

Hypothesis: Clear, measurable statement (e.g., "Creative A will increase conversion among cold prospects in channel X by 20% vs control over 6 weeks").

Primary metric: The single metric that determines success (incremental installs, lift in purchase rate, etc.).

Minimum detectable effect: The smallest uplift that justifies scale.

Sample size & window: Calculated ahead of launch.

Guardrails/stop rules: Time cap, minimum sample, and signal thresholds.

Tagging plan: UTMs, event taxonomy, attribution logic.

Owner & roles: Experiment owner, analyst, creative lead, finance approver.

Budget allocation: % of total marketing spend (e.g., 10% experiment bucket), and max shift allowed if success is achieved.

Use this template to create predictable, repeatable experiments. Make adherence a simple part of campaign briefs so no test launches in the wild without guardrails.

Tactical checklist before you launch an experiment

Case examples: quick wins and hard lessons

One mid-sized brand poured money into a new ad network after impressive early returns. The team celebrated and scaled rapidly. Under a proper holdout test, the uplift vanished - the network had mostly found people who were already in-market and would have converted anyway. The winner? A disciplined experiment with predefined holdouts would have prevented the overspend. This is the exact purpose of the 10% bucket: to afford public failure without jeopardizing the business.

Contrast that with a small app that used 10% to test lookalike audiences, found consistent lift, staged scaling into the 20% bucket, and then gradually migrated the tactic into the 70% core once repeatable efficiency held at larger budgets. Both outcomes show the true value of the 70-20-10 playbook: it makes mistakes survivable and wins scalable.

How to know when to change the split

Revisit the split when your business stage or market environment changes. Early-stage companies often increase experimentation budgets. Mature companies increase core allocation to protect margins. Seasonality, competition, or product updates also warrant temporary shifts. The important thing is transparency—treat the split as a governance lever and make moves visible in planning sessions.

Scaling winners: rules for doubling down

When a test passes the initial criteria, scale in stages. Double spend, review results, then double again if performance holds. Use staged thresholds to catch declining marginal returns early. If a winner breaks down at scale, pause and analyze whether audience saturation, creative fatigue, or inventory constraints caused the drop.

Practical budgeting exercises you can run this quarter

Exercise 1: Baseline audit. List all always-on activities and their CPA/ROAS. Tally the spend and tag the top 80% of predictable returns. This gives you the true core baseline.

Exercise 2: Signal sweep. Identify 3-5 initiatives in the last two quarters that showed positive signals (better CPA, higher engagement, improved retention). Allocate your 20% candidates and create brief experiments to test scale.

Exercise 3: Wild-card pitch. Let any team member pitch an experiment for the 10% bucket—requires a one-paragraph hypothesis, expected outcome, and tag plan. Vote and fund the best two ideas. Keep the experiments short and well-instrumented. For an annual allocation perspective, this guide may help here.

Integrating qualitative insights

Numbers tell you what happened; qualitative research helps explain why. Run quick ad recall surveys, 5–10 customer interviews, or creative focus groups to understand the mechanics behind an unexpected lift. These insights often accelerate the path from experiment to scale.

Role of finance and guardrails

Finance should not be a bottleneck; it should be a guardrail. Define how much budget can be reallocated between buckets without executive approval. Allow fast increases for high-confidence wins but require sign-off for major shifts. Clear guardrails reduce friction while protecting the business.

How to present the 70-20-10 plan to stakeholders

Keep presentations simple and visual. Show the split, the rationale for each bucket, expected KPIs, and two scenarios (best and downside). Use the experiment brief to show what you will learn, and include stop/scale rules so stakeholders know the team won’t run amok with budget.

Checklist: what an effective 70-20-10 governance process looks like

Advanced tactics: attribution, modeling, and synthetic controls

When user-level attribution is limited, use geo holdouts, time-based splits, and uplift models. Synthetic control methods let you approximate a counterfactual when a true holdout is impossible. Always validate models with out-of-sample tests and combine macro indicators like brand searches and site traffic to corroborate results.

Three realistic allocation templates by company stage

Early-stage discovery (high learn): 40% core – 40% scale – 20% experiments. Heavy on learning to find PMF. Growth-stage optimization: 60% core – 30% scale – 10% experiments. Focused on scaling what works while keeping a discovery funnel. Mature enterprise: 75–80% core – 15–20% scale – 5–10% experiments. Prioritizes predictability and shareholder stability.

Final practical tips

Keep naming conventions consistent. Treat creative as a variable. Track qualitative signals alongside quantitative ones. Make tagging non-negotiable. Document failed experiments as well as wins- failure without learning is a waste.

Closing reflection: balance curiosity and discipline

The 70-20-10 marketing rule is less a strict prescription than a governance framework. It balances two human needs—stability and discovery—so teams can protect the business while still inventing future growth. With clear hypotheses, rigorous measurement, and disciplined stop/scale rules, the rule helps organizations turn modest experiments into repeatable engines of growth.

Use the templates above, run the exercises this quarter, and make measurement non-negotiable. Over time the percentages will shift, but the core principle will remain: protect the base, scale what works, and keep a corner of your budget for discovery. Good luck and be curious. See our blog for more examples.

How strict should I be with the 70-20-10 split?

The split is a guideline, not a rigid law. Use it to ensure funds cover sustaining activities, scalable plays, and real experiments. Adjust based on company stage, seasonality, and product changes, but keep clear roles and measurement for each bucket.

How do I measure incrementality when user-level tracking isn’t available?

Use holdouts at the geo or time level, cohort comparisons, uplift models, and macro indicators like brand search lift or site sessions. Server-side event capture and first-party identities help reduce reliance on third-party identifiers.
