Question

How much of a problem is audience overlap? I have a winning adset with one ad. I’d like to make a new adset with a few new ads to the same LLA. Will this impact results?  

Answer 1

Duplicate the campaign then you won't have overlap. And if you mean overlap as far as same people with over a million possible reach it wont matter and will be pennies. By the time you've reached them all it will be time for new creative anyway

Answer 2

You can check the delivery insights in ads manager if you want to know this information.

@wiatt0 I understand you can see frequency and audience overlap for an adset. I’m referring to using the same audience in different assets. Is this still available to see?

Answer 3

If you don't want to have too many campaigns. you can also duplicate the ad set with a slight variation in the creative. hitting new folks within the same audience.
