Social Media Marketing Return on Investment?

I’ve been using Social Media Marketing techniques for a few years now to help brand my small Design company. I can say my brand has definetly increased but I’m now wondering if this increased brand visibility is translating into sales, which is of course the desired and perhaps often forgotten goal. Is my return on time investment worth it?

I’ve only relatively recently got into the habit of asking enquirers where they found me but I can honestly only account for a very small handful of direct sales from my precence and activity on sites such as Twitter, Facebook, Linkedin, The IIA, etc..

I realize that there are other conversion factors ranging from; my market (whether there still is one or not!?), increased competition,  my website usability and ability to convert enquiries but should all of my efforts to brand myself as a professional, accessible and affordable design service provider not account for a little more return?

Off the top of my head I’d say I probably spend a few hours each day reading posts and engaging on Facebook and Twitter especially. I even check these sites first before email these days! I do get lots of great, free info but inevitably I get drawn into entertaining but ultimitately non business related conversations with people I barely know or people who are never ikely to be clients. Result? Time I could and should be spending actually working or maybe learning something new is possibly wasted.

I think these are things I and lots of other social media marketing exponents are going to have to think hard about and try to accurately measure in the near future as the initial social media furore passes.
