We group the creatives together by the creative ID, which means we combine anything together that has the same ID number.
There are times when there may seem like there are two duplicate creatives, but the reason for this is the ID is different on each creative. So when creating new ads in ads manager, it is best to duplicate the ad so the creative remains the same (if needed),and we will bundle those together when viewing performance based on the creative asset itself.
For ads with different creatives for different placements, these will also bundle together. Only true dynamic creatives will be broken up into different creatives when viewing with the Group By Creative option.
