GA4 Comparisons allows you to break down your reports by various attributes.
You could not save comparisons for future use in the past, but now that has changed.
GA4 just released a new feature that allows you to save up to 50 comparisons.
Clicking on the “Add Comparison” button/link will open up an interface to pick an existing comparison or create a new one.
Comparisons are also available in the Admin section under “Data Display”.
Clicking on Comparisons shows you all the current comparisons and functionality to create new comparisons.
