Here are a few other ways to market your product or service on Facebook:
1.) If your business has a blog, import the blog into the Notes section of your profile. This will help keep others you network with up to date on your company.
2.) Create a page for your product or service. You can list important details about what you are offering and message fans of the page with updates.
3.) Create your own group. This can be the most effective of the marketing “tools” on Facebook. You are allowed to invite people to join, post video, post pictures, post links and notes, etc. People who join can really get involved on the group message board and wall.
The great thing about all three of these is every little move you make, it’s posted on all your friends Facebook homepages in the mini-feed!
