With the rise of behavorial marketing online — where marketers serve ads based on where you’ve gone online — there’s also a rising concern about how much privacy we are giving up. Do we realize that marketers are tracking the sites we visit online and that we would need to erase our computer cookies in order to keep that info private? The Federal Trade Commission met to discuss privacy concerns at a public hearing earlier this month, and consumer groups said the FTC should set up a “Do Not Track” database for people to opt out of online tracking (similar to the “Do Not Call” database for telemarketers). But if enough people opt out of tracking, they might also be taking away online publishers’ most effective way of making money. What do you think? Do you care about the way marketers do behavioral or targeted advertising online, and what are you doing about it proactively, if anything?
