There was a time when Facebook was for college kids. Without a .edu e-mail address, you were fresh out of social media luck. But now that the popular site has more than 250 million active users and the fastest-growing demographic is over 35, we all have dollar signs in our eyes and cash register ch-chings in our ears.

Facebook sells ad space and encourages biz owners to use those ads to increase their “fans,” who in turn, willingly receive your company’s messages. But beyond the cost of an ad, is it worth the time? No matter what people say, social media isn’t “free.” Just because you aren’t buying a widget doesn’t mean there’s no cost involved.

I recently met with a prospect who was looking for assitance maintaining his Facebook and other social media sites. At the risk of turning away business, I wanted to know: Why do you think you need a Facebook page? His target audience was one I doubt he’s going to reach on Facebook. He can start building a page and a presence now, but in my estimation, his time, energy and money will be better spent on reaching these targeted high-level professionals more directly — going where they are.

Facebook has its place, and it’s largely a social — and personal — medium. I enjoy following my favorite local band, and I appreciate knowing who Jon Stewart’s guest is going to be tonight, but how many small businesses are generating business (not just fan-dom) from Facebook? Most of us start our fan pages by getting our friends to endorse us. But until that circle grows, that means few business associates that you’re strengthening relationships with and no new consumers receiving your messages. A small-business owner has to decide where his or her social media resources go, and despite having a fanpage myself, I’m not sure Facebook is the place.

I have had indirect and direct business success with Twitter. So, I’m not anti-social-media; I recognize its potential, and I advocate its use — when appropriate — to my clients. But if your target audience isn’t on the medium, how much does it matter if you are? At some point, you’re likely just trying to compete with other small businesses over who has the most fans. And that is not exactly a strategy that wins you business. I welcome any thoughts … and fans on the AVC Facebook page!
