If you do just one thing, I can almost guarantee you will improve your social media success:
Post a good (perhaps even professional) picture of yourself on your social media profiles.
First a caveat: I said a GOOD picture of yourself. Not some quirky, smirky mugshot a la Jared Lee Loughner (that is guaranteed to drive people away). I know that good is subjective, but aim for some of these adjectives: professional, pleasant, smiling, poised, polished, approachable.
The reason is simple: people do business (and connect) with people.
A few days ago, an acquaintance of mine who is notoriously shy and quiet, posted her company logo as her LinkedIn profile picture. What a bad move (and I told her so). After all, are people seeking to connect with her company (where she is an employee and not an owner) or with her?
For some people, putting up a picture seems like an invasion of privacy. For some, there is fear of being judged by looks or the worry that they don’t look good enough. I have heard of women who want to lose weight before posting a picture. Unfortunately, these excuses don’t fly. Social media is social, and social means people. People are not icons or images or logos. They are themselves, and generally a photo captures this.
According to this blog post by Todd Taskey on Small Business Trends, a PROFESSIONAL photo will increase your chances of having business opportunities find you on LinkedIn. More reason to go out and get a professional portrait done. It truly is a worthwhile investment.
