When I start campaigns, I usually make a batch of creatives to test, something like 80 creatives and then test them for a whole week. After a week, I get rid of the losers and keep all the ads with 0.1xx CTR or higher.
At this point I feel kind of lost because everybody keep telling me to test new creatives but I don't know how and in which order. Also, sometimes, the ads that had 0.1xx CTR or higher now has very poor CTR and I don't know how to manage it.
What I'm trying to say is that I know how to start testing but I get stuck everytime when it comes to test another creatives or to move on to the next level.
If someone could point me to the right direction or to give me some tips I would really appreaciate it!
