The 70/20/10 collapse.
Marketing budgets are shrinking. That's the part everyone agrees on. The arguing happens about what to do about it.
Gartner's 2026 CMO Spend Survey put total marketing budgets at 7.7% of company revenue. Three years ago that number was 11%. Forrester's data is slightly more optimistic — 9% of revenue, with 83% of CMOs expecting increases — but the direction of travel is the same. Boards are asking marketing to do more with less and the comfortable middle of the past decade is gone.
Here's the part that doesn't get discussed enough: the budget shrinkage isn't actually the problem. The problem is that most teams are responding to it by shaving across the board — 5% off each line item — when the right move is a complete reallocation. Different shape, not just smaller scale.
What "70/20/10" used to mean
Google popularized the framework in the mid-2000s. The idea was simple: 70% of your budget goes to proven, predictable channels (the core engine). 20% goes to emerging channels you've validated but are still scaling. 10% goes to pure experimentation — things that probably won't work, but if they do, become next year's emerging channels.
The framework survived for two decades because it's simple, defensible to a CFO, and disciplined against the natural pull to either over-invest in what worked last quarter or chase whatever's trending on LinkedIn. It still works in 2026. The numbers just need updating.
The teams winning in 2026 aren't spending more. They're allocating better — and most of them are running something closer to 50/30/20 now.
Why the old ratios broke
The 70/20/10 split assumed your "core" channels were stable. In 2024 most marketers' core was some mix of paid search, paid social, SEO, email, and content. All five of those are now actively being disrupted:
Paid search CTRs collapsed 58% on AI Overview queries. The auction is the same, the click rate isn't.
Paid social still works but Meta's Advantage+ algorithm changes have re-shuffled who wins and who loses every quarter. Yesterday's "core" is today's "we should test this differently."
SEO rebounded sharply (61% of marketers are increasing SEO spend in 2026, up from 44% last year) — but it's a fundamentally different practice now. AEO, citation engineering, structured data. The teams who kept investing in 2018-style SEO are getting lapped.
Email is fine but saturation is real. Inbox open rates keep grinding down. Newsletter substacks compete with your nurture sequences.
Content spend growth has slowed dramatically — only 32% are increasing, 31% are cutting. Volume content lost its ROI when LLMs started generating it for free.
If your "core 70%" is built on five channels that are all in flux, calling it "core" is denial.
The new framework
Here's what's working in 2026, based on engagements I'm running and what the more sophisticated teams I talk to are deploying:
50% — Defensible core
Channels that perform predictably AND have moats against AI disruption. The list is shorter than it used to be:
Branded search and direct traffic. Email-based newsletters with strong sender reputation. Owned community (Slack groups, Circle communities, customer advisory boards). Repeat-purchase / retention programs. The relationships you've already earned, not the ones you're trying to manufacture from cold.
If a channel has been your top-3 ROI driver for 12+ months AND would still work if Google deprecated organic results tomorrow, it lives here.
30% — Reallocate constantly
The "emerging" 20% expanded. Channels that work today but might not in six months. You don't disinvest from them — you stay invested but you stay nimble.
Paid search and paid social belong here now, not in core. So does most SEO. So does LinkedIn organic, podcast advertising, retail media, and creator partnerships. Anything where the rules are changing fast enough that what worked in Q1 might not work in Q3.
Discipline is the key word. Review monthly. Be willing to move 20% of this budget mid-quarter based on signal. The advantage is speed of adjustment, not raw spend.
20% — Real experimentation
The 10% experiment bucket doubled. There's just too much new emerging — AI ad platforms, agentic search, AEO, on-site AI agents, voice — to confine experiments to a tenth of the budget.
This is where you fund the things you can't yet justify on ROI. Building a Wikipedia presence. Writing the original research piece you hope gets cited by Claude. Standing up an AI agent on your site. Sponsoring a small but high-quality conference. The bets that have a 30% chance of becoming next year's "core" and a 70% chance of going nowhere.
If your CFO won't let you fund 20% in experiments, your marketing function is being structurally undercapitalized for 2026 conditions.
Where teams get this wrong
The most common failure mode I see: treating the 20% experiment line as "optional." When Q2 misses plan, the experimentation budget is the first to go. Two years of that behavior and your core stops producing growth — because every channel in your core started life as an experiment somebody protected long enough to mature.
The second most common failure: confusing "emerging" with "experimental." Paid social is not experimental. It's not core either. It needs constant attention but it's a known commodity. Lumping known commodities into your experimentation bucket starves real experiments and overfunds the obvious.
Third: keeping channels in core out of inertia. Direct mail was someone's core in 2014. Some teams are still funding it at 15% in 2026 because it always worked. Audit aggressively. If a channel hasn't been top-3 in your ROI ranking for 12 months, it doesn't belong in core anymore — even if it used to.
What this looks like in practice
I worked with a B2B SaaS client recently who was running roughly 75/15/10 on a $2M annual marketing budget. Their core was paid search (35%), content (25%), and SEO (15%). Their emerging was LinkedIn paid (10%) and webinars (5%). Experimentation was a 10% line item that mostly went unspent because nobody had time to plan it.
We rebuilt to 50/30/20:
Core (50% / $1M): Email/newsletter program (15%), branded paid search (10%), SEO with explicit AEO focus (15%), customer marketing/expansion (10%).
Emerging (30% / $600K): Non-branded paid search (10%), LinkedIn paid (10%), podcast advertising (5%), creator partnerships (5%).
Experimentation (20% / $400K): AEO citation engineering, an on-site AI agent, three sponsored research studies, and a small conference series in their target vertical.
Eleven months in: total pipeline up 31%, CAC down 18%, two of the experimentation lines (AEO and the AI agent) graduated to emerging, freeing up budget for two new experiments. The core didn't shrink. It just did less of the work.
The harder question
Most teams I work with don't actually have a budget allocation problem. They have a strategic clarity problem dressed up as a budget allocation problem.
The real question isn't 70/20/10 vs. 50/30/20. The real question is: which channels are you running because they work, and which are you running because they used to work, or because everyone else is running them, or because nobody had the time to question the line item?
Cut clearly. Reallocate boldly. Experiment seriously. The teams doing this in 2026 will compound past the teams that just trim 5% off everything and call it a budget review.
If you're walking into 2026 budget planning and the math isn't mathing — pipeline targets up, budget flat or down, and the same channel mix as 2023 — get in touch. This is half of what fractional growth advisory looks like in practice.
