You talk to your friend about wanting to buy a new rug and suddenly rug ads are showing up on your Facebook page. There have been plenty of stories like that going around, causing some conspiracy theories about Facebook tapping phone microphones to emerge. There is no truth to them, however. The truth is that your internet browsing habits tell more about you than you think! You might not remember liking pictures of rugs on Facebook or saving them on Pinterest - but that's probably why you are seeing the ads.
