The 95:5 Rule: Marketing to People Who Aren't Buying

Most of the companies on your target account list aren’t going to buy from you today, maybe not even this year, or next. Their budget is committed, their contract runs for another eighteen months, the tool they have works well enough, and they have bigger problems to solve first.

The 95:5 rule puts a number on that. At any given moment, roughly 5% of your buyers are actively in-market. The other 95% are getting on with whatever else needs doing.

For B2B SaaS teams under pressure to show pipeline today, that sounds like bad news. But once you accept that the buying window opens on the customer's whim, your job changes. It’s not about creating demand, because you can’t create demand from nothing. Instead, your job is to be the brand people remember when their window finally opens.

What the 95:5 rule says

The 95:5 rule is a simple observation about buying cycles. Big B2B purchases don’t happen all the time. Companies sign a payroll system, an ERP, a security vendor or an agency, then leave it alone for years unless something catastrophic happens. So on any given day, only a tiny amount of the market is shopping.

Everyone else sits outside the market. They still have eyes and memories though. They read, they scroll, they sit in webinars, they talk to peers. They are forming impressions of who is credible in your category long before they are looking for your solution.

Your future buyers are watching you now, and buying later.

Where the 95:5 rule comes from

The rule comes from Professor John Dawes of the Ehrenberg-Bass Institute, published through the LinkedIn B2B Institute in 2021. His reasoning is arithmetic rather than opinion.

Corporations change major service providers roughly once every five years on average. That means about 20% of the market buys in a given year, and about 5% in a given quarter. Therefore, 95:5.

Dawes is clear that this is a heuristic, not a constant. Your own ratio depends on how long your contracts run. A rough way to find it:

Your in-market share ≈ your sales period ÷ your average contract length

Sell an annual seat-based tool and a quarter might put 25% of accounts in play. Sell a five-year infrastructure platform and the quarterly figure drops closer to 5%. Either way, the majority of your market is out of market whenever you look.

Performance-only strategies are scrapping over the same 5%

Performance marketing is very good at one thing: finding people who are looking. High-intent keywords, review site categories, intent data spikes, competitor comparison searches. It works, and it should keep running.

The problem is that it works for your competitors too. Every vendor in your category has the same intent signals, the same bid strategy, the same keywords, and the same list of ready buyers. You all crowd into the same 5%, and the auction does what auctions do. Cost per click climbs, cost per opportunity follows, and the CAC gets more expensive every quarter.

Then there is what happens inside that 5%. Research from Bain and Google found that 80% to 90% of B2B buyers already have a shortlist of vendors in mind before they start formal research, and around 90% end up choosing a vendor from that original list.

So that means that by the time a buyer becomes visible to your demand gen engine, most of the decision has already been shaped. The shortlist was built earlier, out of memory, from everything the buyer absorbed while they were part of the 95%.

Spending your entire budget on the 5% means competing for a decision that was largely made before you arrived.

What the 95% are deciding before you show up

While they are out of market, the 95% are building something you can see the results of but never the process: a mental shortlist.

Ehrenberg-Bass calls the trigger points category entry points. These are the situations that send a buyer looking, described in the buyer's own words. Situations rather than personas.

For a revenue operations platform, category entry points might sound like:

• "Our forecast was wrong again this quarter"
• "We just closed a funding round and need to hire twenty reps"
• "Finance and sales are reporting different numbers"
• "We're expanding into a new region and our data is a mess"

Mental availability is how easily your brand comes to mind in those moments. Dawes notes that even category leaders typically link to only around half of the relevant entry points in buyers' minds, and getting there takes years of consistent presence.

That is the asset you need to build; mental availability.

How brand investment compounds

Performance spend is like a tap. Turn it on, leads arrive. Turn it off, they stop. The money resets to zero every month.

Brand investment behaves like a balance. A memory formed in March is still working in November. A useful point of view published this quarter keeps circulating. A distinctive look that stays consistent gets recognised faster each time.

Now layer the 95:5 rule on top. Every quarter, a fresh 5% of the market enters the buying window. They arrive carrying whatever memories they accumulated while they were outside it. So each round of brand work keeps earning against every future cohort that enters the market carrying it.

Attention outside the market is cheaper, because fewer advertisers are competing for it. And buyers who already know you convert better when they do show up, with shorter cycles, warmer first calls and less price pressure.

Binet and Field's work on B2B effectiveness points to roughly a 50:50 split between long-term brand building and short-term sales activation. Most B2B SaaS teams, unfortunately, lean to 90:10 in favour of activation.

What to do about the 95:5 rule

Map your category entry points. Interview recent buyers. Ask what was happening in the business the week they started looking. Write down the phrasing they use. Ten to fifteen entry points is plenty to start.

Publish against those situations, not your feature list. The 95% have no reason to care about your product. They do care about the problem that will eventually push them into buying.

Stay recognizable. Same colours, same voice, same faces, same formats. Consistency over a decade is what turns repeated exposure into memory. Rebrands and format churn reset the clock.

Buy cheap attention. Reach out-of-market audiences on channels priced for awareness rather than intent. Podcasts, newsletters, communities, events, organic social, broad-match paid reach.

Keep the 5% engine running. Don’t forget about the other half of marketing. Capture demand properly. Strong comparison pages, clean review site presence, fast follow-up, easy trials. Brand work makes that engine cheaper, and it needs the engine to convert what it creates.

Move the split gradually. Going from 90:10 to 50:50 overnight will break your quarter. Shift ten points a year and watch what happens to blended CAC.

How to measure marketing to people who aren't buying

The usual objection is that none of this shows up in the dashboard. Some of it does, if you change what you watch.

• Branded search volume over time
• Direct and dark social traffic
• Share of voice against named competitors
• Self-reported attribution on your demand forms
• Percentage of won deals where you were on the buyer's day-one list
• Win rate and sales cycle length for accounts with prior brand exposure
• Simple prompted awareness surveys within your target account list, run twice a year

These can help predict what your pipeline looks like in a year or two, even while none of them will close a deal by Friday.

TL:DR Category entry points are your long term branding goal

Only a sliver of your market can buy right now, and that sliver mostly arrives with its mind made up. The 95:5 rule tells you where the decision was actually formed: earlier, further out, among people who were not buying anything at the time.

Marketing to people who aren't buying feels inefficient in a monthly report and looks obvious in a three-year one. Contact us to chat about how we can help you get a better understanding of your CEPs and truly do justice to your brand and marketing.

FAQ

What is the 95:5 rule in B2B marketing? It is the observation that around 95% of your potential buyers are out of the market at any given moment, and only about 5% are actively looking. It came from Professor John Dawes at the Ehrenberg-Bass Institute via the LinkedIn B2B Institute.

Does the 95:5 rule mean I should stop performance marketing? No. The 5% are real and worth capturing efficiently. The rule says you shouldn’t be spending everything there, because that means nothing is building the memories that decide who makes the shortlist at some point in the future.

Is the 5% figure accurate for every category? It is a heuristic. Divide your sales period by your average contract length to estimate your own figure. Short contracts push the in-market share higher, long ones push it lower.

How long does brand investment take to show up? Expect early signals such as branded search and self-reported attribution within two to three quarters, and meaningful movement in win rate and CAC over one to two years.
