EVISA's web site viewed by the major search engines



The indication of content pages by major search engines is a primary factor for the visibility of a web site today. The availability of a huge amount of information for everybody has shifted the major problem from access to evaluation. The huge amount of information presented by search engines within their hitlists can no longer be handled by the searcher who most often will only look at the very first hit pages. Although search engines are programmed to rank websites based on their popularity and relevancy, empirical studies indicate various political, economic, and social biases in the information they provide. Unfortunately, placement of information sources within the hitlists of search engines is not fully transparent, differs between the major search engines and is a complex function of the quality of information, its presentation, and the number and quality of references towards related information and references from other sites pointing towards the site. The EVISA editorial office is continuously working on the quality of information and its appropriate presentation (including the meta data). All information pages do contain links to further information both to internal and external information. The success of the work is monitored by watching the placement of EVISA content pages within the hitlists of the major search engines.
