"The number of Cyberchondriacs has jumped to 175 million from 154 million last year, possibly as a result of the health care reform debate. Furthermore, frequency of usage has also increased. Fully 32% of all adults who are online say they look for health information "often," compared to 22% last year." said Harris Interactive in a study completed and reported in August 2010 with demographics based in the United States of America.
Online surveys: Consumers are asked to complete a survey, including their demographic information and product and lifestyle interests. This information is used as a sales lead for advertisers, who purchase the consumer's information if provided. The consumer may 'opt-in' to receive correspondence from the advertiser and is therefore considered a qualified lead.
