The Journal examined 50 sites using a test computer and discovered that these sites collectively installed a total of 3,180 tracking files—an average of 63 tracking files per site:
The state of the art is growing increasingly intrusive, the Journal found.
Some tracking files can record a person's keystrokes online and then transmit the text to a data-gathering company that analyzes it for content, tone and clues to a person's social connections.
Other tracking files can re-spawn trackers that a person may have deleted.
....Some of the tracking files identified by the Journal were so detailed that they verged on being anonymous in name only.
They enabled data-gathering companies to build personal profiles that could include age, gender, race, zip code, income, marital status and health concerns, along with recent purchases and favorite TV shows and movies.
