Distinguish yourself from other sites with conversion marketing techniques.
How nice it would be if you could simply send out some advertisements via email, pay per click advertising, etc, and have all of the business you want. But, your advertising does not stop there. You need to also apply conversion marketing, which is getting someone to actually purchase something from you. In order to do that, you need to distinguish yourself from other online retailers with a gimmick. This gimmick does not have to be a joke, it could mean offering live help, or discounted items for first time customers, etc. These types of services are part of marketing and without them, you are just like everyone else.
