So I've got an adult sex toys site that I never bothered trying to submit to stumbleupon, or many other bookmarking services for that matter (folkd deletes them, I figure most don't allow adult links). So anyways, three days ago I start getting a boost in traffic, approximately 200 UV per day. Looking at my stats I realized someone had stumbled my store. I thought nothing of it, figured it was junk traffic and it wouldn't convert. Well -- it IS converting. So now I'm scratching my head trying to figure out what's going on. Is it normal for stumbleupon to send 100s of visitors a day? Does it last? Does it only happen when a more "trusted" person stumbles your stuff, or can any stumbleupon result in hundreds of hits a day? If you know the answers, I'd appreciate it. Thanks!
