The Campaign Report includes cost, click, and (optionally) conversion data for one or more campaigns with keywords. By default, the data includes one row for each applicable campaign for each time unit in the specified date range, and the rows are in ascending order first by campaign and then (when applicable) by portfolio.
You can optionally include advertiser-specific label classifications.
You can view data for the previous 36 months.
For descriptions of all default and custom columns, see “Report columns for basic and advanced reports.”
