Press Releases should be posted on the web site under a “News” or “Company News” menu title and then each one should be submitted to popular PR networks which will distribute the Press Release to everyone in their network. The Google Search engine is always searching for news type information on web sites it crawls and higher rank is given to them. These PR Networks also tend to have very high Google ranking. Therefore, by just having your press releases on their site, you benefit by high link popularity.
Costs: The basic service of submitting them to the PR networks would be $10/ press release.
