People are very helpful and I was new at that time so don't no much about Press Release so that' Y I asked.
When you want to write about some new product launched by your website,then at that time we require press releases.
Each month, more than 27 million people in the U.S. use Google News and Yahoo News to find the latest information about a wide range of topics that interest them. When they conduct a news search, they often find relevant press releases along with articles from thousands of news sources. According to Neilsen/NetRatings, the unique audiences of Yahoo News and Google News now rival the online audiences of other current events and global news destinations such as CNN and BBC News. In fact, Yahoo News and Google News now reach audiences that are equivalent to those of major search engines like Ask Jeeves and AltaVista. If your company's marketing and promotion strategy includes the Internet, your press releases should be optimized for and distributed to the major news search engines.
