Question: In setting up a similar audiences list for a Google Ads campaign, Antonio is wondering whether he needs to exclude people from his original remarketing lists. A colleague tells him he doesn't need to do this. Why does the colleague tell him this?
- Because similar audiences don't have any association with remarketing lists.
- Because similar audiences lists automatically exclude people so that only new leads are reached.
- Because similar audiences will automatically remarket to existing leads if it identifies potential value in them.
- Because similar audiences use existing remarketing lists to get as much reach as possible.
Explanation
Similar Audiences are built from a seed audience such as remarketing lists to find new users who resemble the original list. The original seed members are not included in the expansion audience, so a separate exclusion is unnecessary. That keeps prospecting focused on new users instead of overlapping with re-engagement traffic. In current Google Ads documentation, the same rule appears in Lookalike segments, which automatically exclude users in the seed lists. Google Help+1
Why the other options are incorrect
No association with remarketing lists There is a direct association because the similar audience is modeled from the original remarketing list or other seed audience. Google Help+1
Automatic remarketing to existing leads This audience type is for finding new similar users, not for retargeting people who are already in the source list. Google Help+1
Maximum reach from the original list The seed list is used as the basis for expansion, but the seed members themselves are excluded from the similar audience. Google Help+1
