If you are not interested in making a profit from your web site you are most likely going to develop an informative web site. It should be noted that information sites can also be profitable through third party advertisers but the primary purpose is to distribute information and not to obtain sales.
There are several ways to distribute information on the internet. Two of the most popular are archive sites and community sites. An archival, or database, site allows you to offer information on a topic that is usually searchable by topic for your guests. This is preferred for large amounts of information on specific topics. The second is a community site. These allow guests with similar interests to gather in one location and share information about themselves and about their topic of interest. In this instance you would need to make sure the content matched your target audience.
