On the previous question of unique views, I get only ~ 700 -800 day. The niche I am in (ironically - because I didn't plan it this way) has a high CPC, so I get ~ 2$ per click. I take it some of you have been banned using a Pinterest Clone site? Hmm. That may not bode well for me, if that is a criteria for nuking someone (all by itself). Still doing ~ 1,000 pins per day through the machine. I only have 150 followers. I would say (just to answer some other questions) about 75% of my traffic comes from Pinterest. Other 25% spread across Twitter, FB, and other micro-social network sites. I do have a very small delay between pins. PinBlaster really rocks for this. But I think the key is, you MUST have it appear that the pins to your boards are coming as 'pins from your website'. Not pins from your images on your desktop. That's where the custom plugin comes in, etc.
I do not even pin to group boards that often. Maybe once per week, maybe one or two pins without my watermark or anything. just a straight up pin thats super-relevant. Still hovering around $40/day Adsense... but I can see it still slowly climbing.
Could be that you should try to get a good mix of social traffic coming to your Adsense site to really try and insulate yourself and not put all eggs in one basket... so to speak.
In the next 2 weeks will be popping up another pinterest clone and doing the EXACT same thing but in another niche I discovered. I will post back here eventually to let everyone know if that one works as well as this one, or if somehow this one is a fluke of good luck, flying under the radar for some reason, etc.
