Understand the data
The data table shows your data broken out by the Default channel group dimension. For each channel, it shows 2 metrics as calculated by the selected attribution models:
- Conversions: Count of conversions that are attributed to the selected dimension
- Revenue: Amount of revenue that is attributed to the selected dimension
The Revenue metric in the report uses the same calculation method as the one used for the Purchase revenue metric.
The % Change columns show the percentage by which conversions and revenue increase or decrease under different attribution models.
In some cases, Analytics is unable to display dimension values because they're missing or otherwise unavailable. To keep the conversion and revenue credit totals accurate, the report might show one or more of the following values:
|(not set)||(not set) is a placeholder name that Analytics uses when it hasn't received any information for the dimension you have selected. For example, manually tagged URLs could be missing a parameter like campaign, source, or medium|
Unassigned is the value Analytics uses when there are no other channel rules that match the event data
Direct is the value that Analytics uses when there is no path data for which to credit the conversion; for example, data import
|Unattributable||Unable to assign credit for the dimension you've selected|
|(Other)||(Other) is the value Analytics uses for an aggregated row due to cardinality limits. Learn more|
