Yesterday the worst day in 2013! (first time this year (actually in 25 month frame!) back in 2 digits Euro sum, that made no sense at all), CPC at 40% of usual and RPM just 32% of 2013 average RPM - just sucks big time.
however today all metric nearly back to normal mode (as normal as i would expect), just 1/8 of adsense day is complete (Europe), yet already made 1/3 of yesterday's. Most likely will be back to 3 digits zone.
Fingers f**** crossed.
