Some days before the Adsense team had announced a change in policy for AdSense publishers by which publishers from countries other than USA, Latin America and Japan won’t get paid for referring users to AdSense. Till then if you referred a user to AdSense and he mad $100 within 180 days you would also be paid the same amount.
So after the first policy change so many users complained to the AdSense team that they have decided to make a slight change.
The changes to referrals promoting AdSense will now depend on where your users are located, regardless of your location as a publisher. You’ll earn $100 for every user you refer to AdSense who is located in North America, Latin America or Japan when they generate $100 in AdSense revenue within 180 days and they remove all payment holds. You’ll no longer be paid for users you refer who are located elsewhere. These changes will go into effect the last week of January.
There are changes to other referrals too
Google Pack: Currently, you can earn up to $2 when a user downloads and runs Google Pack for the first time after being referred through your link or button. Starting the third week of February, each successful Pack referral will earn up to $1. This change will apply to all referrals for Google Pack and is independent of user location or publisher location.
Firefox: The payments for Firefox referrals from China are also being reduces during the third week of February. This specific referral payment change will only affect installations from users in China. Again, this is independent of your location as a publisher.
This will be a huge letdown to many of publishers. If you are an Adsense publisher and feels this is not fair complain to the Adsense team just like I did.
you can easily earn lots of dollars from adsense if you have a high traffic site.;,*
