It is important to set your campaigns- ad groups correctly so your rules run on what you want.
The campaigns in this list are filtered down to only show the campaigns for your selected ASINs. If you did not select any ASINs, all your campaigns will be displayed.
There are 3 settings on this page:
1 - Only run on Ad Groups with selected ASIN(s)
Selecting this option will ensure that your rule only runs on the ad groups with your selected ASINs. If you select a campaign that has multiple ad groups - but only one of those ad groups has your selected ASIN, then the rule will only run against that ad group. If you did not select any ASINs, this option will be disabled.
2. Select campaign option
There are 3 options
All current ad groups with selected ASINs
All current and future ad groups with selected ASINs
Only selected ad groups with selected ASINs
If you uncheck the first box, the "with selected ASINs" no longer applies and the rules is applied to all the ad groups selected.
3. Search and Select Campaigns
If you select the option for "only selected ad groups", you must select which campaigns or ad groups you want to apply the rule.
