5. Use proactive posting to stand out online (in a good way) While there is a lot to be cautious about when it comes to communicating via social media, that doesn't mean you should pull back altogether on your online presence. The reality is you should do whatever you can, when you can, to build your credibility. That's right: You can, and should, consciously and deliberately craft a positive online image. "For example, if you have a well-written blog about something you are passionate about or if you are a conscientious tweeter informing your followers about interesting news stories, you can actually build a very respectable reputation online," says Kuzmeski. "You should also consider joining the commenting communities on the Web sites or blogs of companies that interest you. By doing so, you can add to their dialogue, and the suggestions and comments you post just might catch the right someone's eye." "Taking these steps shows you know how to use the Web wisely and that you are well rounded, well informed, and a great communicator-factors that every company wants in an employee," she adds.
