I made a calculation recently.. (it's not very accurate but could come closeby..)
Botw on the 12-11-2006:
http://botw.org/new/all/12112006.cfm, total links added that day: 827, let's say that half of that is non-commercial: so aprox 400 times 49.95USD = 19.980,- USD half of that should be paid to the affiliates of botw so thats 9.990,- times 225 working days = 2.227.500,-
Yahoo on the 12-11-2006:
http://dir.yahoo.com/new_additions/20061211/all.html, total links added that day: 321, let say half of them are non-commercial, so aprox 160 times 299USD = 47840,- = no affiliates, so times 225 working days = 10.764.000,-
Maby true, maby not. Who has another opinion about this calculation?
