Study of Healthcare Websites Shows Widespread and Risky Use of Tracking and Analytics Tools
A recent analysis of healthcare websites has revealed that the majority use marketing and analytics tools that could potentially disclose sensitive data to third parties. The study was jointly conducted by Piwik PRO, a privacy-first web analytics platform provider, and Verified Data, an automated audit platform that helps organizations verify analytics accuracy, data quality, and privacy compliance.
