As a best practice, Stephanie’s colleagues have told her that she doesn’t need to exclude peoplefrom her original remarketing lists when using Similar Audiences lists. What’s the reasoningbehind this?

Similar Audiences lists automatically exclude people so that only new leads are
reached.
Similar Audiences will automatically remarket to existing leads if it identifies
potential value in them.
Similar Audiences uses existing remarketing lists to get as much reach as possible.
Similar Audiences don’t have any association with remarketing lists.
