Set some goals for your Facebook marketing campaign. You can launch your campaign on a trial basis if you are not sure how your audience will react to it. Once you get a better idea of how interested your customers are, you should set some reasonable goals for your campaign.
Make good use of Facebook Insights. You should visit this feature on a weekly basis to get an idea of how many people you reached out to. You will be able to get detailed numbers for each updates as well as a weekly number of uses you reached out to.
Create a unique Facebook page that is capapble of standing apart from the rest. The key to marketing on Facebook is to not look just like the other guys. Almost everyone uses Facebook these days, so you must be different if you want to be noticed before one of your competitors is.
Before you begin to use Facebook for marketing, consider if you really have the time to pull it off. You'll need someone to post at least once per day, and then you'll need to include other features such as a Promotions tab or polls. The only way to profit through a campaign such as this is with constantly updated content, but do you have the time?
If you are especially shy, you should find a way to overcome that before you start trying to market your business. People will not clamor to do business with someone that seems to have a hard time communicating. If this is not something you can change, you should consider hiring someone to do your marketing for you.
Your Facebook page needs to contain information that your audience is not able to get anywhere else. If they feel like they are reading old content, it will not give them the incentive to return. Make sure that you offer exclusive content that is only available for people that have subscribed to your page.
