By Susan Grant, Director of NCL's Fraud Center Most consumers don't know that their activities online may be tracked by companies that create profiles of them based on the Web sites they visit, the pages they look at, the ads they click on, what they buy, and other information about their behavior. These profiles help businesses target their ads to those consumers who are most likely to be interested in their products or services. So, for instance, if you're an avid golfer and you've visited Web sites about golf or bought golf equipment online, you may see an ad for golfing vacations to Scotland the next time you visit a travel Web site. This isn't necessarily sinister -- you may want to see ads that are tailored to your interests. But the practice, behavioral tracking and targeting, raises concerns about privacy, security of personal information, the potential for discrimination, and use for other purposes such as law enforcement. Even though these profiles may not include consumers' names, they may contain information that can easily be linked to specific people. On November 1 and 2, 2007, the Federal Trade Commission held a Town Hall that brought members of the online advertising industry together with researchers, consumer representatives, privacy advocates, and others to discuss these concerns. Today, the National Consumers League submitted comments asking the FTC to take action to protect consumers and ensure trust in the online marketplace. One interesting idea, which NCL supports, is to create a national "Do Not Track List" similar to the popular "Do Not Call Registry" for consumers who don't want to be tracked online.
