We have advertising campaigns in several different countries running over the last two weeks. Over this span we have been averaging about 100 conversions (downloads) per day, For some reason, over the last two days we have a total of 8 conversions! Does anybody have any insight as to why this might be? I haven't made any changes to the campaigns during this time. Impressions and clicks are still pretty much where they were before, but for whatever reason the conversions are taking a nosedive. Any suggestions are welcome. Thanks.
Have you checked the country split in the dimension report?
It could help identify where the problem could come from...
Not sure about your hosting solution, but if you are using a shared hosting solution, the server's bandwith might be used by a "big neighbour" resulting in slow / cancelled downloads?
Did you make any changes to your site?
