Population

Quick answer

In marketing, the population refers to the total group of people that a company or business is interested in reaching with their marketing efforts. This might be all potential customers, a specific geographic area, or a targeted demographic. In A/B testing, it helps teams connect a term, metric, or behavior to a clearer optimization decision.

Key takeaways

  • Population gives teams shared language for experiment planning and analysis.
  • It should be tied to a clear metric, audience, behavior, or decision whenever possible.
  • Consistent definitions make optimization work easier to compare across tests.

Definition

In marketing, the population refers to the total group of people that a company or business is interested in reaching with their marketing efforts. This might be all potential customers, a specific geographic area, or a targeted demographic. It is this 'population' that marketing strategies and campaigns are created for, in order to effectively promote a product or service.

What Population means in A/B testing

In A/B testing, Population gives teams a clearer way to describe user behavior, measurement, or decision-making. It is most useful when connected to a primary metric, a specific audience, and the decision the experiment is meant to inform.

Why Population matters

Population matters because measurement terms shape how teams judge experiment outcomes. When the definition is clear, marketers and analysts can connect the result to a real user behavior, metric, or business decision instead of relying on vague performance claims.

Example of Population

For example, a growth team may test a new landing-page message and use Population to understand whether the change affected the intended behavior. The term helps turn a test result into a specific next step instead of a generic statement that the page performed better or worse.

How to use Population

Use Population as part of your experiment documentation. Define the metric or behavior it refers to, choose where it fits in the funnel, and use the same definition when comparing results across tests.

Common mistake

A common mistake is using Population as a vague label instead of tying it to a measurable behavior or decision. If different teammates mean different things by the same term, experiment planning and result interpretation become less reliable.
