The field
Cost in
Shopping Performance Report should return the sum of the CPC and CPM costs during the specified period. You may set the
includeZeroImpressions to
false to return Cost values that are non-zero, however, even if it is set to false and the Cost value is 0 but there are some other specified metrics fields that have non-zero values, then the row will still be returned in the report output. Since Cost is of type
Money, this will return data in micros (x 1,000,000). I'm afraid you have to do the conversion on your side.
