Lee Odden at the Top Rank Blog lists the positives of gaining visibility for a business, site or organization within the News Search Engines of the Internet and gives some tips on how to get your site included somehow in these engines.
* Research web sites that are already trusted news sources and work on getting your articles or press releases published with them.
* Submit press releases though wire services such as Business Wire, PR Newswire, PRWeb or MarketWire that supply news.
* Apply to become a trusted news source. If your site produces frequent, original content, and/or has multiple contributors and a clear editorial process, then you may qualify as a trusted news source:
Apply to Google News – Suggest a news source
Apply to Yahoo News – Suggest a local source or a source for news and blog search
For Topix.net find the relevant news category and click on the “Feedback” link at the bottom of the page
