Dr. Joseph Mercola provides another article detailing how Google and some health related websites violate people’s privacy by placing tracking cookies (a.k.a. spyware) on a visitor’s browser to track and record searches and purchasing choices. Dr. Mercola specifically cites WebMD and Healthline. Now, I have used both those websites just for information, because over the years I have spent a lot of time researching medical and nutrition information, mainly for personal reasons. But I will say that Dr. Mercola’s website has been useful in many cases, for information-seeking and for general articles of interest.
