Build Your Brand on Social Media
I provide some answers in this post at the Search Engine People blog. A taste:
Answering questions from people about the way your industry or business functions is a sure-fire way of making yourself look like an expert (provided you actually know the answers). Look through topics related to your business on sites like Quora and LinkedIn and set up a saved search on Twitter and look at hashtags. Join industry forums and participate in discussions. Use web search and Google alerts to find more questions on those topics. Don't just answer for the sake of getting your name in: you need to actually add something informative to the discussion.
