Remarketing Using Existing GA Segments
This popular discussion was copied from the former Help Forum, answered by Dan Stone (Member)
Question: I created a new segment in GA called MAC OSX Users ( Where user OS is Macintosh). I used this segment to create a Remarketing audience which I intend to use in my linked Adwords account to target Mac devices.
When I use this segment as a filter in GA, I can see approx 4000 users. However, the remarketing audience created using this segment shows 0 users.
Note: I just enabled 'Remarketing and Advertising Reporting Features in Google Analytics'. Does that mean that the Remarketing Audience I created will only collect data going forward?
Answer: Yes, you needed to enable remarketing in your Google Analytics tracking settings for the audience to accumulate users. Give it 1-2 days and please respond if you're still encountering an issue.
