social media presence
While maintaining your own blog is a great idea, you should also consider contributing to other, more-established, online communities within your industry or field of interest. The value lies in the fact that every piece of content you contribute -- which has your name attached -- may reach hundreds or even thousands of new people. All of whom can find their way back to your website or Facebook page.
When I get an endorsement "Jeff Chatterton is great at event planning," I know it's the latter. It's just someone trying to curry favour. How do I know that? I hate event planning. I don't do it, because I suck at it, and I know that. Here at Checkmate Public Affairs, if I need to stage an event, I have other people that I know will do a better job than I do the work. I've had one person, who I met at a speech I gave in Iowa, endorse me upwards of 20 times. Another former colleague is running for political office, and I've probably received a dozen endorsements from him. All it does is clog my inbox.
