Making money online through Adsense and other ad networks

I do experience it myself. Once in a while, when I check my Adsense channel data and then my sites' aggregate data, I find out that they don't match. Oftentimes, the earnings that the Adsense channel shows is higher than the Aggregate earnings. I just dismiss it and think that it Google Adsense reports do get some glitches every now and then. Or that they update the Adsense channel reports faster than the Aggregate data.

However, I didn't know that many Adsense publishers have noticed this irregularity, too and didn't waste time on informing the big G about it. So, voila! Here are the reasons that the Google Adsense team revealed behind the channel vs. aggregate data irregularities:

1. Your ads are being tracked on multiple URL channels.
2. Your ads are being tracked on both a URL and a custom channel.
3. Your ads are being tracked on multiple custom channels.

So it's all about tracking multiple channels, huh?
