I am not sure if it is the right place to post this, but if it is - I would love to get some assistance on the topic.
I am a drop shipper, and I made 3 video ads + 3 thumbnails for my product.
Obviously I need to do creative testing to find out which video ad + thumbnail are the best.
That is why I created 1 Adset with 9 advert That look like this -
VIDEO 1 THUMBNAIL 1
VIDEO 1 THUMBNAIL 2
VIDEO 1 THUMBNAIL 3
VIDEO 2 THUMBNAIL 1
VIDEO 2 THUMBNAIL 2
However, I don't understand if I need to put an interest when doing the creative testing or just keep it broad with the basic (US, 21-64+, etc..)
I would really appreciate your help on this one!
