I came across this method in a mall just around my area. It was a stall, 2 good looking girls that are very good at convincing people, guys specially, and a flat screen television showing what you can get if you register by submitting your email and confirming it. They even said they'll add your email in a smal raffle draw. We all know that it's pure BS, but I found it really smart. Lastly, 2 computers in which a page is open ready for sign up. They also gave away small keychains, water bottle, and small things in return. I tried it, forgot exactly what CPA company as I was just redirected to the sign up page. It thought it was smart, and honestly speaking, they fooled a lot of people. Though, I still doubt how this works. Conversion rate would be 100%, same IP, and a lot more. Any insights on this?
