new form of advertising is selling "tagged words" we say or have in our profiles. Facebook uses something similar. If you use french, some advertisements will be in french!!! Even though you have absolutely no idea what they mean! Do I agree with it ? No. It's a sale of information without examination of what we actually write. It's "Tagged words". So in that case, it linked your book with a searched item with the same tag on amazon.
