Searches for health information are one of the most common reasons that consumers use the Internet. Both consumers and quality experts have raised concerns about the quality of information on the Web and the ability of consumers to find accurate information that meets their needs. Researchers have found that the processes by which consumers locate health information on the Internet, and the evaluations they make regarding which Web sites to visit, are important variables in the quality of information they ultimately view and use. It is of great importance to understand factors influencing online searches for health information and to develop technical and educational approaches for maximizing quality and benefit of health searches.
