I made a different YSM account and put ads in there copied from my old account that has been running okay in the search network. On the first two days, conversions was good and a very low cost per conversion. The following days were not good because I didn't get a number of conversions and the cost was high. I checked on my other account and the same thing was happening in there. I know G doesn't allow double serving ads but I don't know about Y. I tested and I think probably I got the answer. Does anybody have an idea?
