The preferred way to display ads on PeepSo stream is to use Ad Group. Create an ad group called: “PeepSo Stream Ad Group” (or however you want it to be named).
It’ll be easier instead of creating placement for this position for every ad separately - which of course is your choice, as it will work like that as well.
However, placing all PeepSo Stream Ads in one group gives the opportunity to be able to manage everything in one place.
Managing ads in a group is handled by Advanced Ads in the groups view:
For details on these, please go to Advanced Ads documentation.
