I'm running campaigns for over $2.5K per day mostly on adwords content network. Things have been very steady till over the past 4 days all my accounts are showing a 20%-30% decrease in traffic. I'm running on various verticals and GEos so I find it hard to believe it's competition. Does anyone experience the same issue? Can you think of a reason this is happening beyond competition? Thanks.
if you're using content network you should take a look to this thread: http://forums.digitalpoint.com/showthread.php?p=11021468#post11021468
Competition, the economy, participants may have changed or they may have internally changed what is required to appear (raised rates).
