Definition

This can be actions like "Save for later," "Add to wishlist," or "Share with a friend.

What Secondary Action means in A/B testing

In A/B testing, Secondary Action 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 Secondary Action matters

Secondary Action 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 Secondary Action

For example, a growth team may test a new landing-page message and use Secondary Action 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 Secondary Action

Use Secondary Action 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 Secondary Action 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.
