Has anyone successful converted a third party campaign (Adwords) into the new Yahoo system? I've been back and forth with Yahoo Support with no solution yet. It seems that the Yahoo system is very picky the type of CSV file imported.
It's not a straight download from one upload to the other, but requires a bit of formatting. If you call Yahoo they will send you the new template, then its just a matter of copy and pasting from your exported Adwords campaign into the YSM template. Pretty quick and painless.
