Hello all, If you don't use Google Ad Manager then look away now, the following won't make any sense When adding an impression based line item I am asked, as you would expect, for the total impressions to deliver and a start date. However it also asks for an end date as well. For an impression campaign I don't want to use an end date as the end of the campaign is once all impressions have been served be that in 24 hours or 24 months. Knowing how many page views I typically receive I suppose I could guesstimate an end date + 30 days (just in case). However this strikes me as being somewhat unreliable (especially if there is a banner rotation in place for a particular slot), and I really don't want to have to deal with an advertiser complaint when their campaign ends with only 80% of paid for impressions served. So the question is, using Ad Manager is it possible to add a impression based line item with no end date.
I can tell you that it is definitely possible with uniQlicks. We initially tried GAM but found it to be unnecessarily inelegant, one of the reasons we developed uniQlicks.
