Changing Duration of Audience: YouTube Audiences
I have several videos on YouTube, and separately I'm running ads. If someone watches one of these videos I'd like to exclude them from seeing any of my ads for the next week. I should be able to do this with a remarketing list, but here's my problem:
In the Shared Library > Audiences section, there are 6 YouTube-based remarketing lists (Liked Only, Disliked Only, Shared Only, Visited Only, Visited Channel Only, Subscribed [Channel] Only).
I want to change their membership duration but can't (currently set to 365 or 540 days each). Is this possible? I'd make a duplicate list, but don't know how to define the rules so that previous viewers won't see ads.
