One feature that distinguishes the drupal content management system from its peers and in a way places it a cut above the rest is the taxonomy module.
Taxonomy refers to the classification and organisation of content on a website in a manner that facilitates the users' usability experience. In his best-selling book, Don't make me think, Steve Krug explains that visitors to a website expect to find information without effort. He makes the valid point that the ease with which a client finds the information, product or service they are looking for ultimately has a positive impact on a company's bottom-line and objectives. The opposite is also true. A visitor to a mashed-up website where the content is not clearly organised into clearly layed out categories becomes frustrated by the experience and more often than not, clicks away from that site.
Using the taxonomy module, a drupal website's content is divided into categories or topics and then content is linked to the broad any one of the relevant topic or category. For instance, a news website can have the following categories, Business, Sports, Technology, Arts, International News and Gossip.
Visitors to the news websites then use these categories or topics to zero in on those stories that match their interests.
According to Krug, "people are good at satisficing, or taking the first available solution to their problem, so design should take advantage of this" by organising content under topics or categories.
