If you have tried to sell anything online, your own stuff or as an affiliate, you know how important is to convert your traffic. That especially applies if you’re paying for the traffic. Every single visit is important as it may result in a sale.
Many visitors come to your site and read it, they may or may not like what you are offering them, and they may leave your site without buying. But have you ever wondered how much of a push did they need to buy your stuff? Maybe a little tip would have been enough, maybe you’d not buy with a gun in their face.
