Is it possible to limit the number of people in a campaign? e.g. after getting 1000 people seeing a banner those 1000 people continue to see it, but no one else does, even if they meet all the targeting requirements.
I have a need to do this in Target Classic immediately, but would also like to know about Target Standard
It's not possible to limit the no of people in a campaign . However you can change the Success metric advanced options to give you the ability to define custom behavior for both content viewing and counting when visiting a success metric. Please see the following for Information
Also, , you can change the percentage of visitors to be included in the campaign or test defines the total percentage of your qualifying visitors who will see one of the experiences of this campaign. The remaining percentage of users will see the default content for the mbox. Please see link
