lol, there are many theories on this... one of them can be found here: http://www.rainbowskill.com/internet-fundas/why-is-my-adsense-earnings-going-down.php However, even though it mentions a cause, it does not provide a solution to that which is what everybody is looking for.
i ever notice that in first 15 days of each month is best than the last 15 days in adsense earning, if any 1 feel the difference than i am right?
- you shouldn't see much loss if your content is not localized on india. if it is wide then you should have wider visitors getting some true clicks and money. - economy is bad causing a decrease in click cost by 15-20%. if your growth rate is more than 15-20% then you should see more money in your account.
Please give us some details: Is the amount of traffic the same as before? Are the traffic sources the same? Is the traffic coming from the same countries as before? There are so many things that can influence the amount of money that you earn via adsense.
I have mentioned this before on a thread i notice that the beginning of the month the clicks are average or above then by the 20th of that month it below average I noticed this in the past three months. Getting back to the economy yes the small guys do not pay that much to advertise but the big guns are throwing more money on the table before than recession to get as much consumers to keep buying there product otherwise those companies will lose thousands so its the small guys that get hurt buy this so called recession.
More companies are increasing online spending and reducing traditional media spending...only online can give you definitive numbers
i totally agree with you. i have got lot of decrease in my adsense earnings because 50% of my visitors are from india and other 30% are from asian region.Although i am receiving same amount of visitors as before
