June '11 was my worst month of the year - lowest traffic, second-lowest CTR and lowest earnings. If I can avoid another Panda-mauling (knock on wood) this year should show a BIG improvement. We'll see in 29 days.
Things are looking fairly average here. I've come to the conclusion that some clicks are processed more slowly than others, thus accounting for some wild day-to-day fluctuations. My overall revenues month-by-month have been quite stable.
