Seeking and Sharing Health Information Online: Comparing Search Engines and Social Media

Search engines and social media are two of the most com-monly used online services; in this paper, we examine how users appropriate these platforms for online health activities via both large-scale log analysis and a survey of 210 people. While users often turn to search engines to learn about seri-ous or highly stigmatic conditions, a surprising amount of sensitive health information is also sought and shared via so-cial media, in our case the public social platform Twitter. We contrast what health content people seek via search engines vs. share on social media, as well as why they choose a par-ticular platform for online health activities. We reflect on the implications of our results for designing search engines, so-cial media, and social search tools that better support peo-ple’s health information seeking and sharing needs
