Behavioral targeting (BT) combines a consumer's online activity with psychographic and demographic profiles compiled in databases. Social networking is the fastest-growing area of BT. Specifically, the information that social network members willingly share on their profiles in combination with demographic and psychographic information becomes a very powerful tool for ad placement. Critics call this form of BT "conversational eavesdropping analysis," whereas advocates call it "user-declared information targeting."
