I know July and August are the bad months of the year. The deadly drop start on August the 2nd, on August the 4th i've reached 1.71USD. Who else experienced on that day a low earning? And how come?
To be sincere, August was one of my best month in the history of my account. So, I think it depends on the market, niche, advertisers and other factors.
For some reason I have my success during the summer months for some reason. Maybe its because of all the kids that aren't in school.
