What is the 95-5 rule?

The 95-5 rule says that at any one time about 95 percent of business buyers are not in the market for what you sell, and about 5 percent are. Professor John Dawes of the Ehrenberg-Bass Institute set it out in a 2021 paper. He calls it a rule of thumb, not an exact count.

Who is in the market, by how often a client buys. A client who buys every five years: 20 percent are in the market in a year and about 5 percent in a quarter. Every two years: 50 percent in a year and about 13 percent in a quarter. Computers: 75 percent of companies buy once every four years. Banking: 80 percent of companies change once every five years.

The sum behind it is short. Dawes writes that companies change a service provider, such as their main bank or law firm, about once every five years. So about 20 percent of them are in the market in a year, and about 5 percent in a quarter. LinkedIn's B2B Institute, which works with his institute, adds that 80 percent of companies change banking services once every five years.

How do you work out your own 95-5 number?

Ask how often a client like yours buys. Dawes takes a category bought every two years: half the buyers are in the market in a year, and about 13 percent in a quarter. In the interview he goes one step further, to 4 or 5 percent in a month. One survey question gives you the interval.

His question is plain: how often do you buy this, or how many times in the last year did you go looking for a new supplier? For a coach or a consultant the same question works on a call. When did you last hire someone for this, and when before that?

Then do the sum for your posts. This part is ours. A typical post from an account with 1,000 to 5,000 followers is seen about 470 times, in The Shield Index's count of 50,000 posts. Say every reader could hire you and 5 percent are looking this quarter. That is about 23 people. The other 447 are next year's clients.

Why do buyers not respond to posts right away?

Because most of them cannot buy yet. Dawes says advertising works mainly by building memory links that come to mind when a buyer does enter the market. LinkedIn asked B2B marketers how soon they expect a campaign to work, and 96 percent said within two weeks. Buying cycles run to years.

What marketers expect beside what the buying cycle allows. 96 percent of B2B marketers expected the main effect of an ad campaign within two weeks, in a study by LinkedIn. About 5 percent of buyers are in the market in a quarter, when clients change provider every five years, by John Dawes's sum. Marketing works on memory first, and the sale comes when the buyer is ready.

In the interview he gives a second reason sales are lost. Buyers weigh very few suppliers, often two or three, even where twenty five compete. So the usual cause of a lost sale is that you were never thought of. For someone who sells their own time, a post is one way a name gets on that short list before the search starts.

The paper also has a warning for anyone who works in bursts. Spend the whole budget in one quarter, Dawes writes, and you are off the air for the rest of the year, when other buyers come into the market.

What should you post for the 95 percent?

Posts that tie your name to the moments a client starts looking. Dawes calls these buying situations, or category entry points: we need a quote quickly, we need a supplier with a local office. For a consultant they might be a new finance chief, a failed audit or a funding round. Then stay visible all year.
