One of the most powerful tools a recruiter can use to attract more clients is publicity.  Not only does publicity provide free or low-cost advertising, it can lend credibility to your name and allows existing (and future) clients to hear your story. Here are a few tips for publicizing your company effectively.
Tip #1 - If you're a small or one-person firm you can probably use a company such PRWeb to distribute press releases and spend a little time each week networking with journalists who may be interested in hearing what your company has to say.
Tip #2 - Take a little time to find out what you have to say.  In other words, what's newsworthy about your organization?  Does your company work with disadvantaged youth?  Did you recently win an award or industry recognition? These are the types of news items that you could announce to clients and potential clients via a press release.
Tip #3 - Don't forget that once you create a press release or a journalist writes an article about you, place it everywhere--on your website, in industry newsgroups and forums.  Place the press release in as many places as possible to increase the exposure of your company.
