The 95/5 Rule: Why Most B2B Marketing Budgets Are Backwards

At any given moment, only 5% of your target market is actively in-market to buy what you sell.

The other 95% are not.

Most B2B marketing budgets are spent obsessively chasing the 5% — and ignoring the 95% who will need you in 6 to 18 months.

This is the most misunderstood pattern in B2B marketing, and it is costing companies a significant portion of their growth potential.

Where the rule comes from

The 95/5 rule originates from research conducted by the Ehrenberg-Bass Institute, the marketing science research organization at the University of South Australia. Their 2021 paper, authored by John Dawes, established that B2B buyers spend approximately 5% of their time in active buying mode and 95% out of it. The pattern has since been replicated across multiple categories and geographies.

The intuition behind the finding is straightforward. Most companies do not buy most products most of the time. A given B2B buyer might evaluate a new CRM every five years. A new payroll system every seven years. A new agency relationship every three years. In any given week, almost none of the buyers in any given category are actively shopping.

The 5% number is not literal. It varies by category, length of consideration cycle, and external pressure. But the pattern — a small minority of buyers in-market at any given time, a large majority out-of-market — is universal in B2B.

Most B2B marketing budgets are spent obsessively chasing the 5% — and ignoring the 95% who will need you in 6 to 18 months.

Why the math is so unforgiving

If you only market to the 5%, three structural problems work against you.

First — you are competing with every other vendor in the category for the same small audience. The 5% who are in-market right now are seeing ads from you and your six biggest competitors simultaneously. Your share of voice in that moment is, by definition, much smaller than the category as a whole.

Second — the in-market window is short and the decision is fast. By the time a buyer enters active shopping mode, they often already have a shortlist in their head. Vendors who waited until the in-market moment to introduce themselves are arriving too late to make that shortlist.

Third — the cost per impression is highest at the moment of in-market intent. Search ads, retargeting, and intent-data tools all charge premium prices to reach the 5% precisely because every competitor is also bidding on them. You are paying top dollar to compete in the most crowded portion of the funnel.

The 95% opportunity

Here is the asymmetric opportunity inside the 95/5 rule.

The 95% who are not in-market today will eventually be in-market. When they enter that buying window 6 or 18 months from now, they will already have a shortlist in their head. The shortlist is built from the brands they already remember.

Memory takes time to build. Mental availability — the likelihood that a buyer will think of your brand when the buying moment arrives — is not built during the moment of intent. It is built during the long stretch of time when the buyer is out-of-market.

This means the marketing investment in the 95% is functionally an investment in future in-market moments. You are not trying to convert today. You are trying to be remembered tomorrow. The cost per impression is lower, the competition is less fierce, and the compounding benefit is enormous.

What in-market versus out-of-market marketing looks like

The two modes require different content, different channels, and different metrics.

In-market marketing is built around intent. Search ads, retargeting, comparison tools, product pages, free trials, sales-led demos. The message is conversion-focused, the asset is decision-stage, and the metric is pipeline contribution.

Out-of-market marketing is built around memory. Brand campaigns, thought leadership, podcast appearances, broad-reach social, category education, conference presence. The message is identity-focused, the asset is awareness-stage, and the metric is brand recall and aided/unaided awareness.

Most B2B marketers have been trained to disdain the out-of-market work because it does not show up in attribution dashboards the way conversion-stage work does. This bias has cost the industry dearly. The brands that compound in B2B are the ones that invest in being remembered when the buying moment arrives — not just the ones that show up at the moment itself.

Three brands that figured this out

Salesforce. Twenty years of category-defining brand investment when the rest of the CRM market was running pure performance campaigns. The result: Salesforce is the default vendor in the mental shortlist of nearly every enterprise CRM buyer, even buyers who eventually choose competitors. The brand premium compounds across every renewal cycle and every category expansion.

Drift. Built their brand on aggressive thought leadership in conversational marketing — books, podcasts, conferences — long before the category had real urgency. When the conversational marketing moment arrived, Drift was the default. They were eventually acquired at a valuation that other vendors in the same space could not approach.

Gong. Built their brand on relentless category education — sales research reports, frameworks, podcasts, original data. The bulk of that content was aimed at sales leaders who were not actively buying revenue intelligence software. When those leaders entered the buying window, Gong was already in their head.

Three signs your B2B marketing is over-indexed on the 5%

Run this audit on your current marketing investment.

•   Sign one — almost everything you measure is bottom-of-funnel. Conversion rate, cost per lead, pipeline contribution, attribution. If you do not have meaningful measurement of brand awareness, aided recall, or category share of voice, you are not measuring 95% of where your market spends their time.

•   Sign two — almost every campaign is conversion-focused. Free trials, demos, gated content, pricing pages. If you cannot point to three current campaigns whose goal is awareness rather than conversion, you are not investing in the 95%.

•   Sign three — no investment in brand. Brand investment is the asset class that pays back over years rather than quarters. If your CFO has not approved a real brand budget, you are running an all-performance strategy in a category where compounding mental availability is the actual game.

How to rebalance

The mature research on B2B marketing budget allocation suggests roughly a 60/40 split between brand-building and activation. 60 percent of budget on the long-term work that builds mental availability. 40 percent on the short-term work that converts the in-market 5%.

Most B2B companies are running closer to 90/10 in the opposite direction. 90 percent activation, 10 percent brand. The ones that survive the next decade will be the ones that rebalance.

The math will not feel intuitive to a CFO who is used to monthly attribution reports. The work of explaining the math is the work of the modern marketing leader.

A 90-day plan

Three things to do in the next 90 days if this post has hit a nerve.

•   First 30 days — audit your current budget allocation. Build a simple two-column spreadsheet. One column is brand/awareness spend. The other is activation/conversion spend. Map every dollar. See where you actually sit.

•   Second 30 days — commit to one new brand investment. A podcast presence, a thought leadership program, a category education series, a conference sponsorship. Pick the channel that fits your audience and start showing up consistently.

•   Third 30 days — establish measurement for brand impact. Brand tracking surveys, aided awareness studies, share of voice analysis. You cannot manage what you do not measure. The reason most marketers default to performance is that performance is measurable.

Brand investment is measurable. It just requires different instruments and longer time horizons. The companies that build those measurement systems will pull ahead of the ones that do not.
