You must be having the idea of Facebook page and the role-played by the fans on it. You can promote anything to everything by creating facebook page and adding fans to it.
You always need to attract more fans to your page and by the following trick you can easily add more fans to your facebook page.
Add More Fans
The simplest of tricks, which you can use to attract more fans to your facebook page, is to have some contest. By having contest you are increasing the chance of getting attention of your fans followers too. Since, all are pretty much interested in contests.
Therefore, having contest once or twice a week can easily increase the number of fans on your facebook page.
In contests do give something valuable to them – you can either give some computer accessories, Internet plans, or memberships to other sites. This all depends on the kind of budget you have for your marketing.
But my honest suggestion would be to not give way any crap ebooks for free. Since, this will only degrade your contest offer.
Therefore, share wisely and grow rapidly.
