How top health websites are sharing sensitive data with advertisers

A network diagram showing how ad tracker patterns vary for the same website from country to country. Using the example of health.com, it shows 113 nodes with 246 connections in the US, but only 39 nodes and 39 connections in the UK

“The data shared included:

  • drug names entered into Drugs.com were sent to Google’s ad unit DoubleClick.
  • symptoms inputted into WebMD’s symptom checker, and diagnoses received, including “drug overdose”, were shared with Facebook.
  • menstrual and ovulation cycle information from BabyCentre ended up with Amazon Marketing, among others.
  • keywords such as “heart disease” and “considering abortion” were shared from sites like the British Heart Foundation, Bupa and Healthline to companies including Scorecard Research and Blue Kai (owned by software giant Oracle).

In eight cases (with the exception of Healthline and Mind), a specific identifier linked to the web browser was also transmitted — potentially allowing the information to be tied to an individual — and tracker cookies were dropped before consent was given. Healthline confirmed that it also shared unique identifiers with third parties.

None of the websites tested asked for this type of explicit and detailed consent.”

“Called Screenwise Meter, the iOS and Android app gave users who opted into Google’s Opinion Rewards program gift cards in exchange for tracking their internet usage data. The iOS version of the app relied on Apple’s enterprise program, which allows for the distribution of apps with special privileges to be used only by a company’s employees. The app has now been disabled on iOS, though it’s still available on Google’s Play Store. ”
