In Publicity and Credibility Through Writing, marketing strategy expert Rosalie Hamilton writes:
When your expertise is publicized in articles and books, it does not look like advertising, it does not feel like advertising, but, delightfully, it works like advertising. Publicity is, in fact, the best promotional avenue after networking. Even better – it is usually free.
Appearing in publications as a writer confers credibility and authority upon the author. Your profession may even demand that you have peer-reviewed, published works. One tangible benefit from writing is that attorneys search the Internet for publications related to the subjects of their cases in order to find related, qualified expert witnesses. Being a published author can create additional publicity in the form of media interviews, book signings, and book reviews. While writing requires a tremendous effort, the benefits of being published definitely make the effort worthwhile.
