How do I make them run at the same time?
Can I exclude them from being shown together?
If you want to make sure the campaigns are shown simultaneously you will have to choose the Inclusivity function. This is found under Edit Campaign Groups in the box which says Exclusivity/Inclusivity. You must bear in mind that you cannot have more than 5 campaigns in an inclusivity group.
If you on the other hand wish to make sure that the different campaigns are not shown simultaneously you can choose the Exclusivity function.
