Hello everybody, I really could use some tips from you guys. My CPC dropped from 0,08/0,10 to 0,04 since last year. It could not be much but last October I made around 55€/day (average) and this year only can reach 26€/day (average). Last year My best day in October was 140 € and this October I can hardly reach at 50€. It’s a educational site from Portugal so it only profit in the school months. (From October to May) My SEO it’s optimized I think… I have lots of traffic around 20.000 views/day (average) and 650 clicks/day (average). I don´t know what else can I do. I have made some upgrades in my server in order to turn my page faster, I´m running some A/B tests on adsense, trying Autoads, change some keywords but nothing is working… I can only raise from 0,04 to 0,05. Anyone have any idea what else can I do to improve or at least have the same results of last year?
