Suppose that I put up an Adsense referral unit. Someone clicks on it and signs up to the program, but places on his website only referral units. Someone else clicks on that ad and does the same. The cycle may repeat many times until someone decides to place an actual ad unit which earns him 5 bucks within those initial 180 days. The result will be that all people in the referral chain will earn $5. Could this be a true story?
From my understanding you will only gain that $5 bonus if the first person makes the money from ads not referrals.
is it really like that. i dont use referral ad units but i heard that once someone got much less than 100$ from adsense referral.
Yep, I already placed referral units on all websites, with some endorsement for visitors to use those features. None of the sites is technology/webmasters related yet I think some people will still sign up. Question: how to better optimize the referrals on non-webmasters sites?
