hi, i’m amr — the 95-5 rule is probably the most quoted idea in b2b marketing right now, and it is often used to justify the wrong thing. it describes the market. it does not tell you how to split your budget.
what the rule actually says
professor John Dawes of the Ehrenberg-Bass Institute observed that at any given time only about 5% of b2b buyers are in-market. the other 95% are not. companies change providers roughly every five years on average, so in a given quarter most of your future customers are not looking yet.
the budget split is a separate finding
the budget number comes from a different place. Les Binet and Peter Field, in their paper on the five principles of b2b growth, recommend about 46% on brand building and 54% on short-term activation. the 95-5 idea explains why brand matters. the 46/54 split is the allocation suggestion. confusing the two leads to teams putting 95% of spend on brand, which is not what anyone published.
the reason brand spend pays off is shortlists. a b2b buyer study quoted in the minimba write-up found that 80-90% of buyers already had a vendor list in mind before research started, and 9 in 10 chose from that day-one list.
what to check before you move budget
- count how much of your current spend is activation only: branded search, retargeting, bottom-funnel linkedin ads
- ask recent customers which vendors were on their day-one list and whether you were one
- track branded search volume and direct traffic as a slow signal of memory, not just last-click leads
- keep an activation floor so in-market buyers can still find you
- review the split once a quarter instead of reacting to one month of pipeline
how this connects to the rest of the stack
brand work shows up late and indirectly, so your analytics need to credit it fairly. a weak attribution model will always favor activation, and that bias pushes budget back toward the 5%. positioning and messaging also matter here: awareness spend on a vague message builds nothing.
start scaling — if you want a pipeline plan built on your real win rates instead of a borrowed rule, let’s connect.
