Hi,
I wrote an in depth article on this subject that you can view here
Basically it talks about how promoting an ebook can not only increase your revenue (due to the ebook sale), but also increase your poker or casino room revenue.
Not everyone coming the your site will be looking for a poker room or casino to play at. They may only be looking around for a forum, strategy, and so on. Some people are already playing at a room they like and don’t have much of a reason to switch.
This is where an ebook comes in. Many people who buy an ebook want to “win like that pro” who write the book. So, it is a great idea to push the room or rooms that the ebook “pro” plays at. There are many ways to do this, and you may be surprised to see your revenue increase.
If you are looking for a poker related ebook to promote, then I suggest you try Sit N Go, N Win! You can view the affiliate page here (http://www.sitngonwin.com/affiliate.htm). By promoting this ebook, you will also earn great bonuses, including free quality advertising, quality links to your site, and even $1,000 cash bonus on top of your $40 per sale.
