Metric groups

Overview

This topic explains what metric groups are and when to use them. A metric group is a reusable list of metrics you can use to standardize metrics across multiple experiments.

For example, if you have a standard user sign-up flow, you could create four metrics that track customers clicking the sign up button, entering their personal information, adding payment information, and clicking the submit button. By combining these four metrics into a funnel metric group, you can then attach that group to all of your sign-up-related experiments, ensuring you’re tracking the correct metrics for each step within each funnel.

You can view your metric groups from the Metrics list on the Metric groups tab:

Metric group types

There are two types of metric groups: standard metric groups and funnel metric groups.

Funnel metric groups

A “funnel” is a marketing model that describes a customer’s journey through your purchasing or conversion cycle, typically from the awareness stage to the purchasing stage. LaunchDarkly’s funnel metric groups use multiple metrics to track the performance of each of the steps in your funnel over time.

When you create a funnel metric group, ensure that each metric measures a required step in the user journey. If end users skip a step, the results may be incomplete or misleading and will skew your experiment results. Experiments using funnel metric groups treat the final metric in the funnel metric group as the primary metric for determining the result of the experiment.

To include a metric in a funnel metric group, the metric must:

• have a custom conversion binary, clicked or tapped, or page viewed type.
• use the “Occurrence” measurement method. To learn more, read Measurement method.
• use the “Average” analysis method. To learn more, read Analysis method.

Custom conversion binary metrics and clicked or tapped metrics are most often used in funnel metric groups.

Standard metric groups

Standard metric groups are for use with A/B experiments and guarded rollouts. Metrics in standard metric groups can appear in any order. To learn more, read Creating experiments and Guarded rollouts.

The “Metric group connections” section includes information about any experiments or guarded rollouts the metric group is connected to:
