But with adsense...... imagine he has 20k followers, post reach is 10% for example ( 2000 ) , say 20% of the reached people click into the link (400) ..... 2 big post per day for example cus you don't want to over do the link stuff = 800 web visitors
adsense ctr = 1%
adsense cpc = $1 ( I don't know what is it like for music keywords/genre??)
1% of 800 = 8 people click = $8 per day
Please tell me what I am missing.... but for me, with FB & adsense you would need 200k fb followers at least..
