The free viral e-book is a great tool to start looking for new players and affiliates to introduce. However, let's not forget that it's just one of a huge number of tools that you get for this purpose. One fantastic tool is the "grab-a-grand" contest.
For those of you not familiar with UK slang terms - a grand is 1,000. In this case it refers to £1,000, equivalent to around $1,800. The method is very simple, you advertise the contest using one of a number of different buttons and banners which are made available to you (see below for a selection) and whenever anyone clicks to enter they are sent information on the benefits of playing in an online lottery syndicate along with their contest results.
This is a very effective way to advertise - the take up rate is 6%, which is very high. So have a look at those banners and feel free to click on one and enter. Who knows, you might be the next one to win a grand!
By the way, this is just a very small selection of the tools available. There are plenty others to choose from!
