Provide new and engaging content and integrate your FB presence with other social media so you have multiple avenues for reaching folks. Include your FB Business Page URL in your other social media profiles (Twitter, Pinterest, YouTube, etc.). I tend to point all activity towards my blog (CoachPopsinator.com), as I have the most control over content there.
I’ve connected my business page to my twitter feed, so every post I make it tweeted simultaneously (and automatically). I often embed posts from my FB business page into blog posts, so someone reaching my blog from a source other than FB can see the FB post related to the entry they’re reading.
There are a variety of groups that sponsor “FanPageFridays” or “FaceBookFridays” where the focus is promoting your page and sharing the “likes”.
BTW, I’ve liked your page (as well as the other listed in the comments above) please stop by www.facebook.com/CoachPopsinatorFitness to return the favor 🙂
