Today is looking like the same pace as the past 7 days or more. It looks to end up like a typical 4/10 or 5/10 day of earnings. If it's consistent, it's not a glitch. That's the troubling aspect of this.
This month so far has been diabolical and I wondered if it was because at the start of the month I switched to a responsive design. So I dug through some data as everything I am seeing is coming down to cpc being slashed.
This months CPC compared to the same period last month is 50% down. I checked this against the same periods for June & July 2012 and noticed the same thing where cpc for the first 2 weeks of July 2012 was approx. 50% less than for the same period in June 2012. Interestingly I checked the rest of the month for July 2012 and noticed that my CPC jumped right back up so I am hoping that it will do the same this year or else I am looking at a terrible month.
