First of all, I've read enough posts where people saying that SU gives you pretty useless traffic, so no need to flood the topic repeating same thing. I tried to search older topic about monetizing stumbleupon traffic, found few ones that talked about it, but almost all of them went off topic after the second post. + They are old. I got about 33k people from SU in 3 days on my blog. Most of the traffic comes from US and Canada. Seeing big numbers is fun. Although the traffic is pretty useless. Bounce rate was 66% and they stayed for almost 1 min on the page. I tried CPA offers, did not work. Put adsense then for a while. It got 900 impressions and 0 clicks. So, does anyone had any success with this kind of traffic? Please share your experience or ideas. I will share mine : ) - Tried Free ipod/ipad offers. Got few clicks, no leads. - Tried Browser game offers. Same here .. few clicks, no leads. So I guess SU users don't like to give their emails away. If they don't, then building email list won't work either. The question is .. what will?
