Why adsense earnings sometime dies

Hi

I would like to know why sometimes adsense earnings dies for some days. I was getting a regular flow until last month and suddenly it has dropped to almost 10% of the original.

Its has also happened in the past, after some days it starts again... There is no major change in my sites.

Thanks

 

Advertisers drop out or lower their bids.

Your site got smarted priced (google: adsense "smart pricing")

 

I think it also depends upon traffic.

 

but the traffic is almost same... sometimes even higher

 

It has nothing to do with the gross amount of traffic a site receives.

 

it's all about what bids are being placed at the time. Adsense doesn't get a static fee for advertising it changes all the time and that's why some days your adsense will change

 

Some time due to the lack of advertisers the ads are not relevent to the site content, and naturaly the clicks dies.

Sometimes the advertisers target only USA or Canada or Australia etc.. if the visitors are out of these region will have only crap ads so clicks considerably decreases.
