Yesterday saw a slight improvement, though not quite up to average daily earnings. This morning's CTR is starting well, though CPC always gets re-estimated during the course of the day. No idea if things will pick up or continue on a downward trend.
From August 2011 until around March/April 2012, I had a great deal of consistency, and continual improvements with each passing month. July 2012 was good, but otherwise it's just been a rollercoaster ride.
