Since Facebook is a heavyweight in social media and it is filled with targeted traffic, you can easily use it to get some money into your pocket through affiliates.
For you to achieve this, you will have to build your email list then promote a product with a high gravity of over 300.
Have your squeeze page setup with an attractive headline then have about 10 follow up emails going out on your autoresponder with links promoting this product.
Use related fanpages and groups for posting your ads with affiliate links. Target your traffic right to increase leads or sales. This technique is a very effective strategy as long as you make sure you are allowed to post your links in the fanpages and groups.
