Currently, conversion attribution to campaigns is universal i.e. if a visitor responded to a campaign “30% off on laptop” but ordered a food processor; the laptop campaign still gets an order attribution.
While it is possible to subrelate campaigns and products (and their classification); it is very difficult to compare effectiveness of several campaigns in the same report. It should be possible to specify target product or a product classification for a campaign which then filters out any unrelated conversions for the campaign.
