There are several ways to get quick and easy. Here are the one I use and have always given me a very good result:
1. Go www.gigalo.es and www.myntmarket.com pages. Here you can get thousands of followers on Facebook, Twitter, etc.. for only 5 to 10 €. Not all the fans who get here are "real." Some are automated bots. But if you're looking to impress with the total number of followers, then you do not care if all are real or not.
2. If you're looking for real followers for your online store, then I would recommend signing up on sites like www.totombola.com or www.unabuenarecomendacion.com.
Here you can hire a drawing for one of your products, you get hundreds (even thousands) of followers to your website. The good thing with this type of fan is that they are all 100% real and very active on your Facebook wall.
