The 95-5 Rule: Most of Your Buyers Aren't Ready to Buy (And That's the Point)

Most of your marketing budget is aimed at people who will never buy from you this quarter. That's not a failure of targeting. It's the correct strategy.

The 95-5 rule, developed by Professor John Dawes of the Ehrenberg-Bass Institute, makes this case directly: at any given moment, roughly 95% of potential B2B buyers are not actively in-market. They're not researching vendors. They're not comparing pricing pages. They're not talking to sales. They're simply not buying right now. The original paper, "Advertising effectiveness and the 95-5 rule: most B2B buyers are not in the market right now" (Dawes, 2021), grounds this in a straightforward observation about purchase frequency. If the average B2B buyer purchases a category once every five years, then only 20% are in-market in any given year, and roughly 5% in any given quarter with a 90-day decision window.

One implication most marketing teams actively ignore: if you only advertise to buyers who are ready right now, you are invisible to the 95% who will eventually make that decision.

Where the Rule Comes From (And What It Actually Claims)

Dawes was clear about the limitations of his own finding. "The 95% figure is not meant to be a precise rule," he has said. "We're using it as a heuristic." That matters. The ratio is not a law of physics. It is a frame for thinking about purchase timing across a population.

Actual in-market percentage for any given category depends on how often buyers purchase and how long their decision window is. Forrester makes this explicit: B2B martech buyers are closer to an 85:15 ratio, while enterprise banking buyers align with the classic 95:5. A CRM product with a three-year renewal cycle and a 90-day decision window works out to roughly 92:8, not 95:5. The formula is simple: in-market percentage equals your measurement window divided by the average time between purchases.

None of this undermines the core argument. Whether the split is 95:5 or 85:15, the majority of your potential buyers are not raising their hand today. Advertising that only reaches active researchers misses most of the market, by definition.

LinkedIn's B2B Institute picked up this research and ran with it, evangelizing the 95-5 framing widely after 2021. Their practical conclusion: advertise mostly to buyers who are not likely to buy from you today, because that is how you secure future cash flows. Many serious B2B marketers have since shifted budget allocation away from the old 80% lead-gen, 20% brand model toward splits closer to 50:50 or even 40:60 in favor of brand. LinkedIn cites clients who have moved 60-70% of their budget into brand advertising targeting out-of-market buyers.

Marketing Week has called the 95:5 rule "the new 60:40 rule," positioning it as the successor to the 60/40 brand and performance framework that Les Binet and Peter Field established for consumer goods.

The Real Problem: Short-Termism at Scale

Why most B2B marketing teams ignore the 95% is not ignorance. It is incentive structure.

Marketing teams are measured on pipeline, MQLs, and this quarter's lead volume. Every dollar spent building mental availability with buyers who won't purchase for two years looks like waste under those metrics. So the budget flows toward Google Search, intent-based targeting, and retargeting pools that serve the 5% who are already researching. The 95% get nothing.

That strategy works, right up until it doesn't. Once you've captured every in-market buyer in your addressable pool, growth stalls. You've drained the pond. And because you spent nothing building your brand with the 95%, the next wave of buyers has no memory of you when they enter the market.

Patrick Gilbert covers exactly this dynamic in Never Always, Never Never. In chapters on light buyers and mental availability, the book draws on Ehrenberg-Bass research to show that brands grow not by extracting more from existing customers or current-intent audiences, but by expanding reach into the larger population of occasional and future buyers. The 95-5 rule is the B2B version of the same argument. Most buyers are light buyers. Most buying moments are future buying moments. If your advertising only runs when someone is already searching, you've already lost the battle for their mental availability.

Connecting the two frameworks is straightforward. Mental availability means being the brand that comes to mind when a buyer enters the market. You cannot build that recall by advertising only to the people already in the market. By the time they're searching, the memory structures are either there or they're not.

The Contrarian Challenge: Is 5% Even Right?

6sense, using AI-driven behavior modeling across its customer base, reported in 2024-2025 that roughly 40% of accounts show meaningful buying activity at any given moment. Their argument is that the 95-5 rule was derived from B2C contexts and maps poorly to complex B2B cycles, where buying signals can be detected well before a formal purchase process begins.

This is worth taking seriously, but it doesn't defeat the core argument. It reframes it.

If 40% of accounts are showing some form of buying signal, that still means 60% are not. And "meaningful buying activity" as defined by an intent data platform is not the same as "ready to make a final purchase decision." A buyer researching the category casually, a junior employee benchmarking competitors, a company that evaluated your product eighteen months ago and went dark: these all generate signals without representing near-term revenue.

Forrester's position is probably the most useful: treat it as "not a rule, but not a myth." The ratio varies by category and should be calculated for your specific business rather than assumed to be exactly 95:5. But the directional conclusion holds. Most of your buyers are not ready to buy right now. Advertising as if they are is a structural mistake.

What This Means for How You Actually Spend

Operationally, the 95-5 rule is a budget and creative question. Who are you making ads for, and what are those ads trying to do?

Buyers in the 5% who are in-market need demand capture: search ads, retargeting, sales outreach, pricing pages, case studies. Be easy to find and easy to choose. This is where most B2B marketing budgets already go, and it remains necessary.

Reaching the 95% requires a different approach. You are not trying to generate a lead. You are building a memory. You want your brand connected to the category entry points that will be active when these buyers eventually enter the market. The specific problem they'll have. The specific moment of frustration that triggers a search. The mental shortcut that makes your name the first one they type.

Jenni Romaniuk's work on category entry points, covered in depth in Never Always, Never Never, explains why this matters mechanically. Buyers don't enter markets in a vacuum. They enter them through specific triggering situations: a team that's grown too fast, a contract renewal coming up, a new executive who wants to change tools. Brands linked to those situations in memory win the consideration set before the formal search even begins. Distinctive brand assets are part of how you make those links durable.

Strategically, the split is not brand versus performance. It's timing: advertising to people who are ready now versus advertising to people who will be ready later. Both are necessary. The mistake is assuming that only the former generates returns.

We've worked through this tension with clients at AdVenture Media repeatedly, and the pattern is consistent: teams that allocate everything to in-market capture grow until they plateau, then struggle to understand why the pipeline dries up.

The 60/40 brand and performance split framework offers a practical starting point for thinking about this budget division, though the right ratio for any B2B business depends on purchase frequency, category dynamics, and the calculation Dawes laid out.

The Heuristic Is the Point

Treat the 95-5 rule as a number to be precisely right about, and you'll miss what it's actually for. Dawes built it as a heuristic, not a constant. Its value is the attitude shift it produces: stop optimizing entirely for buyers who are ready today, because that group is a small fraction of your eventual revenue.

Leading B2B marketing teams in 2026 are running two distinct programs in parallel. One built for conversion, tightly targeted, performance-measured, designed for the 5% with active intent. One built for memory, broadly distributed, brand-measured, designed for the 95% who will matter later. That second program is harder to justify in a quarterly review. It is also the one that determines whether you have a pipeline problem two years from now.

Evidence from Ehrenberg-Bass is clear. Les Binet and Peter Field's IPA DataBank research on long-term brand effects points the same direction. Short-term activation captures existing demand. Long-term brand building creates future demand. The brand vs performance marketing debate usually treats these as competing priorities. They're not. They serve different buyers on different timelines.

Ninety-five percent of your future revenue is sitting in that second group, not paying attention to you yet. The question is whether you'll be worth remembering when they are.
