The 95:5 Rule
When you need this method
Your budget flows almost entirely into channels that pick off in-market prospects, paid search, retargeting, comparison sites. Cost per deal climbs because every competitor bids for the same 5 percent, while the 95 percent of future buyers do not have you on their shortlist when their buying trigger arrives.
Approach
- 1Split the marketing budget by audience: addressing the in-market 5 percent (capture) versus building the brand with the 95 percent out-of-market.
- 2Invest in mental availability for the 95 percent: recognizable messages, consistent presence in the audience's channels.
- 3Define the buying situations in which the brand should come to mind, and tie messages to them.
- 4Set expectations on the time horizon: brand effect on out-of-market buyers only shows at their next buying trigger.
- 5Keep capture channels running, but stop treating them as the sole growth engine.
Typical application
A typical case: a B2B SaaS in the finance space raises its paid search budget three times in a row, but the extra deals fail to appear, the in-market pool is simply exhausted. The team starts publishing systematically for the 95 percent: expert pieces and recognizable theses in the audience's channels. Over the following quarters, new prospects increasingly report having had the company "on the radar for a while" when their buying trigger arrived.
Limits and counter-indications
The rule is an average across markets; the actual in-market share varies by category and buying cycle. Brand building with the 95 percent works with a long delay and is hard to attribute short-term, which demands patience in budget discussions. For companies in acute pipeline distress, reallocation alone is no solution.
How to measure impact
Suitable observations: the share of new customers who already knew the brand before their buying trigger (self-reported), plus the trend in cost per deal in capture channels.
