Hello all, i have a question for you... i'm the owner of about 10 travel related websites, all with adsense inside... During last 2 years, i everything was fine, and i discovered that the CPC increases in months till july, and then go down slowly... Obvious, 'cause before summer there is more competition on travel keyword And then... why my CPC was 0.20 in March, 0.14 in April, and 0.10 in May?
