i noticed tht as well..my earnings kept on decreasing..da amount of clicks were da same tho its just that those ads paid less..den it got worse i started getting like 1 cent per click
hmmm.. diff of 4$ to 7$. Don't worry, it happens with most of us. Wait for few more days then your older days will come after these days
that's the reason y u earn so less. is it possible for u to share the website link, we can have a look
Because so many web developers have read posts about some guy can make hundred thousands a month and they realize people can make a living with adsense, so they want a piece of the pie, too.
