How to get free traffic from Facebook?

Hi, can you tell me some good strategies to drive traffic from Facebook?

I dont have money so I can do PPC currently, so I am only looking for methods with no initial investments.

I trying to build an email list so if your method relates to my what I am trying to do even better

Any help is appreciated, thank you!

start interacting. go to groups and pages in your niche and interact with the community. its slow and hard, but since you don't have the budget for PPC, it's your best plan of attack.
