While I would recommend experimenting with different types of posts, videos seem to be the most popular content format at the moment. According to a study by Buzzsumo on 880 million Facebook posts published by brands and publishers, videos get, on average, twice the level of engagement than other post types. If you’re posting videos, remember to optimize them for mobile consumption.
A Facebook Fan Page gives you a direct pipeline to your Fans. You can send messages to Fans all at once or target individuals or groups by country, state, city, gender, and even age range. Using the Events App, you can even schedule special events or promotions and then send invitations to only those Fans who live in or near the town where the event is scheduled to take place. All of this and more is available free of charge to any business or brand using Facebook.
If you're interested in online marketing, setup email software and create a lead magnet that you can use in your sales funnel. Then, build up that list. It's often said that you can expect to earn about $1 per subscriber per month. If you have a list of 10,000 subscribers, that means you can earn roughly around $10,000 per month. You will need to deliver value and not pitch them on every email, but it is a very achievable goal in a short period.
We’ve all heard those horror stories about folks who accidentally published personal content to their employers’ social media channels -- a marketer’s worst nightmare. So to avoid publishing mishaps like those, assign Facebook Business Page roles only to the employees who absolutely need it for the work they do each day. And before you do that, be sure to provide adequate training to those who are new to social media management, so they aren't confused about when they should be hitting "publish," what they should be posting, if something should be scheduled first, and who they should be posting it as.
