According to a new Pew Internet and American Life Project report, 10 million American adults look online for health information in any given day. Unfortunately, 75% of searchers do not consistently check the source and date of the content they find online. Additionally, most internet users start at a search engine when looking for health information online. Only 27% of health seekers began at a health-related website.
The most common health topics searched online include information about a specific disease or a particular medical treatment, nutrition information and exercise/fitness topics. Over 50% of all health seekers report that the information they found online affected a decision about how to treat an illness or condition.
