I have a problem that I set up a retargeting audiences on the google analytics. It performed well and I made a test I saw everywhere our ads. But after that suddenly disappeared. I don't know why.
I deleted all the made audiences and recreated all. It worked properly again, but after one week it stopped. I haven't changed anything since I created these retargeting audiences.
Does anyone have any idea what could be wrong?
Does anyone have any ideas about retargeting / remarketing? I would love some good ideas.
