Customize the report

The report builder for a detail report has four sections, each explained below: Report Data, Charts, Report Template, and Summary Cards.

Once you have finished making changes, click Save. An alert will notify you if any collections contain the report that you are modifying.

Report Data

The Report Data section is where you set the dimensions and metrics that appear in the report table.

In the report builder, click Dimensions to control the list of primary dimensions that will be available in the table. For example, in the screenshot below, the Dimensions editor shows the dimensions User medium, User source, User source/medium, etc.

Use the Dimensions editor to control the primary dimensions that are available in the report table drop down menu. See example screenshot, below.

Drag dimensions so that they appear in the order you want, remove and add dimensions, and Set as default the dimension that you would like to appear in the table by default. Click Apply to apply your changes and go back to the report builder.

In the report builder, click Metrics to control the list of metrics that will display (as columns) in the table. In the Metrics editor, drag metrics so that they appear in the order you want, and remove and add metrics. Click Apply to apply your changes and go back to the report builder.


You can have up to two visualizations at the top of a detail report.

  • If you don't want one or both of the visualizations to appear, toggle one or both of them off.
  • Select the type(s) of visualization you want.
  • Drag a visualization to change which of the two visualizations appears first in the report.

Report Template

To unlink or link (see Linked reports, below) a report, click Unlink/Link [unlink]. Unlinked objects cannot be linked in the future, once you save the report changes.

Summary Cards

In this section of the report builder, you create cards that relate to this report. These cards can then be used to assemble overview reports. You can skip over the Summary Cards section if you don't want to create any cards for this report.

You won't see your summary cards reflected on the report. The cards you create become available to use in overview reports.

For each card you create, you must set at least one dimension, one metric, and one visualization. You can only select dimensions and metrics that are used in the detail report.

Linked reports

Linked objects (e.g. linked reports) receive updates from Google. For example, if Google adds a dimension to the User acquisition report, the dimension will automatically be added to all linked User acquisition reports.

Reports that you create from templates are linked by default and automatically receive updates.

Changes that you (or another administrator on the property) have made will not be impacted. For example:

  • Metrics or dimensions that you (or another property admin) have added or removed aren't impacted.
  • Charts (visualizations) that you (or another property admin) have added or removed aren't impacted.


If you don't want a report to receive updates, you can unlink it.

Objects (e.g. reports) that you create from scratch are unlinked by default.
To unlink a report, click Unlink [unlink] in the report builder. Unlinked objects cannot be linked in the future, once you save the report changes.
