Hello - we've come across the same question a few times from the business and our Adobe Target admins.
We're seeking to do some onsite personalization via Adobe Target, using 3p audiences we built using an Audience Marketplace data provider. Given that these are 3p cookie pools, devices have already qualified for the segment. So when they land on our website for the first time, will they see the personalized experience (first page) or would need to take an action on our website to qualify?
Many thanks-
Marc K.
