Hello friends, I have been advertising on tiktok for 4 days. I have tested 4 videos and one is going mega well. with the remaining videos, I only have canceled checkouts and many shopping carts (8-10 per day) where what goes well with 20€ adspent, reached 7 buyers!! What should I do next? I duplicated the video that goes well 2 times and ran it to 20€ in another campaign for today. This one has advertised with 7€ ads, but 8 add to carts has not yet reached a purchase. Should I scale vertically next and pack the 2-3 winning ads into a CBO? If so, with how much budget? If not, what to do then?
