1. Build your online presence. The Internet is a perfect place to start showcasing your knowledge. Post comments on blogs, write your own posts, and connect with other bloggers to create a network.
2. Win some awards. Identify awards that matter in your industry and don't be afraid to nominate yourself, or convince colleagues to do it for you.
3. Flaunt well thought-of affiliations. Your associations aren't always in your control but if you have a degree from a top school or testimonials from important people, display them prominently. Credibility by proxy is valuable."
