I like that it's an easy way of tracking where my advertisements are being displayed, making sure they aren't wasted in areas with little advertising exposure or too many ads cluttering up one area! We can easily adjust our budget by knowing how much we have spent so far vs what remains until next month/quarterly report comes out (or when funds run low).
There isn’t really anything i dislike about this program - if you're looking into monitoring your ad spend from beginning-to end then definitely give them some consideration as their platform meets all needs perfectly well without any flaws at present time.
