Breakdown
Breakdowns turn an overall number into a more diagnostic view. They can reveal that growth is concentrated in one market, a conversion drop affects only one device type, or a new release performs differently across versions. Analysts should use properties with reliable values and avoid creating so many small groups that the results become unstable or hard to interpret.
What is Breakdown?
A breakdown splits a metric or event by a property—such as country, plan, campaign, device, or app version—to show how different groups contribute to the total.
Why it matters
Breakdowns turn an overall number into a more diagnostic view. They can reveal that growth is concentrated in one market, a conversion drop affects only one device type, or a new release performs differently across versions. Analysts should use properties with reliable values and avoid creating so many small groups that the results become unstable or hard to interpret.
Example
A 10% decline in purchases looks alarming overall, but a breakdown by app version shows the drop exists only in the newest Android release.
