I get asked this question – a lot.

I read many incorrect answers – a lot.

The right answer matters – a lot.

Confusion Reigns

This is one of the most asked questions I have encountered since creating the buyer persona concept a dozen years ago.  What concerns me today with the rising interest in buyer personas, is how often this question is answered incorrectly.  The result is confusion in many areas.

First, a look at the usual confusing – and incorrect – answers proliferating today:

  • A buyer persona should be created for every role
  • Buyer personas are built for every function and department
  • Create a buyer persona for each different marketing message
  • Create a buyer persona for every role on the buying team
  • We need to create a buyer persona for each campaign
  • We should have online and offline buyer personas

The biggest source of confusion relates to three primary areas:

One, is equating a buyer persona to a role.

Two, a narrow tactical focus on marketing messaging.

Three, the focus of the buyer persona reads like a job description.

Some of the best buyer personas researched and created have been role agnostic.  They became significant game changers to business strategy.

The opposite can happen.  Where there are an inadequate number of buyer personas.  Causing an organization to miss out on a significant new opportunity.  Causing the one or two buyer personas used to be overly generalized and useless.

Finding The Right Answer

To understand the right answer, we must first understand foundational principles related to all personas in general.  Personas are representative archetypes, which models behaviors.  In psychology, archetypes are used to model various norm and atypical behavior.  In the design world, personas are used to model usage behavior.  In the business world, buyer personas are used to model buying behavior.

What is it about the relationship between buying behavior and buyer personas you need to know?

When seeking deep buyer insights about buying behavior qualitatively, one of the primary insights we look for is goal-directed behavior – in our case – goal-directed buying behavior. Goal theory is one of the building blocks of many of the social sciences such as psychology and anthropology. Goals are powerful human drivers.  They can exist at the conscious as well as the subconscious level.  Many powerful goals live at the subconscious level.


How does this apply to the question we are looking at?  The answer can be presented in this way:

If the archetype of business and personal goals related to one buying group is distinctly different from that of another buying groups, it requires a unique buyer persona. 

As mentioned above, some of the best buyer personas I have seen researched and created were role agnostic.   The best way to get this across is to use an actual example:

For one large enterprise software organization, on-site buyer interviews were conducted primarily in operations functions.  For the sake of this example, the buyers usually were Senior Director of Operations to Chief Operating Officers.  We uncovered a deep profound insight, which was unexpected.  If you think operations, you think efficiency.  Are you not thinking this now?  For one buying group, this was true.  However for another, there were very distinct goals emerging around expansion and growth.  This was true on both a business and personal goal level.  For this example, we have one-segment yet two distinct buyer personas in the same approximate archetype roles and functions. 

This company served two primary segments.  A simple graphical representation looks like this:

Important Principle

This is one of the most important principles for creating informing buyer persona.    In the example mentioned, this resulted in software enhancements, new sales enablement approaches, and new sales tools to meet buyer goals.   This can affect the effectiveness of content marketing at a strategic level.  While messaging may have a common platform, addressing the goals of distinct buying groups takes some different perspectives.  More than just mapping to buying stages.

For senior executives, do not miss this principle.  I have seen great cases were an unexpected new buyer persona and market opportunity came out of such research and insight.  Resulting in a significant leap over competition or entrenchment of a leadership position.
