"we no longer do all the manual work as we did before, the algorithms do it for us - updates settings and select what ads to run at what time. I know what ads to run and what works in a completely new way. it’s also very nice to have someone to throw ideas with and who feedbacks on my questions regarding optimizing and algorithms."
