To add a new widget, you need to go through 3 basic steps. Open your dashboard, click on the Edit Mode button on the left
and then in the right sidebar click on the “Select Service” drop down menu. After that, select a specific data source, for example, Google Analytics, select Account, and Sub-source. In Google Analytics, most often that is “Reporting”.
Click the blue NEXT button.
The next step is to select an Account and Profile of the website and one of the pre-defined widgets.
After that, use one of the pre-defined widgets, or create a custom widget by selecting Segment, Dimension and Metrics.
The last step is to select dimensions of the widget (dashboard is grid-based, 4 columns), graph type and, if needed, change the name of the dashboard.
