Everybody tracks you.
The 3 things you can do about it:
1. Browse in private mode only.
2. Delete all your cookies regularly.
3. Set the 'Do not track' option in your browser
I would like to know how and who is tracking my online activity so that when I go to any web page, items I have recently viewed at online shopping sites appear as ads on those pages. This REALLY infuriates me and I want to know how to prevent it.
