The Bottom Line • Most consumer health information sites have trackers • About half have tracking from 3rd party advertisers • Commercial sites most commonly • Government sites least commonly Burkell and Fortier
The Bottom Line • Recommended sites have less tracking • But only because information professionals are more likely to recommend government sites • Commercial sites that are recommended are no better than those returned on Google with respect to tracking, not-for-profit sites are actually worse Burkell and Fortier
