I have a bunch of sites, some reaching over 4000 UV per day, and I have never really tested adsense referrals out. Are they really worth putting them on? What sites do they typically work good on? If anyone is experieanced with referral buttons, please let me know so I can ask you some questions if at all possible. Thanks!
If someone downloads firefox from your blog and installs .then you generate $1 iff the computer which downloaded firefox already had firefox , you generate 0.$1. If someone signs up from the Adsense banner from your page. Then the money new blogger generates profits you with the same amout the new one generated. and if the new one get $100 within 180 days you are overloaded with bonus of $250. If you want more informations on adsense you shouldn't miss astace.blogspot.com It helped me a lot.
I've gotten two referrals, but I guess both haven't reached $100 yet so I haven't received the $250 payments. Figuring it's your site and all, I'm sure it was very helpful. [/endsarcasm]
I do very well by the FF referrals (that's why they call me the Referral King.. Google has written about us a few times).. I do 'ok' with the GooglePack referrals (not near as well as the FF).. And a few times a month i get a $5 Adsense conversion.. still looking for one of the $250 conversions..
Never earned anything from adsense referrals, but I've never really focused much effort on it. I think it does require more effort and thought, compared to targeted ads.
