Spec: A/B Testing Events

On this page


This guide explains what data should be sent to Segment from A/B Testing tools and hence is targeted to partners who send A/B testing data back into Segment rather than targeted to customers themselves. The semantic events detailed below represent the ideal for A/B Testing events.

Overview

Every A/B Testing tool is built around the concept of showing visitors an experiment with changes to the page. Each experiment can have multiple variations shown to different random samples of visitors.

Events

The one semantic event for recording A/B Test experiments is:

Experiment Viewed

This event will be sent automatically every time a customer sees a variation of an active A/B Test when using some A/B testing tools via Segment. You don’t actually have to make these track calls! Note that the A/B testing tools will need to be loaded synchronously in order for these events to fire properly.

Properties

This event supports the following semantic properties:

Property Type Description
experiment_id String The experiment’s ID.
experiment_name String The experiment’s human-readable name.
variation_id String The variations’s ID.
variation_name String The variation’s human-readable name.
