Microtargeting: How campaigns know you better than you know yourself

Political ads on the airwaves have been so pervasive this year that voters in battleground states probably see them in their sleep. But when a political spot pops up while surfing the Web, there’s a good chance it’s aimed right at you.

The practice is called microtargeting and like a lot of marketing techniques on the Internet aimed at identifying consumer tastes and behaviors, it is an information-age approach that is helping change how political groups identify and interact with voters.

Moreover, microtargeting may give pollsters, campaigns and interest groups a sharper idea of how candidates and issues may fare at the ballot box, raising concerns about personal privacy in a medium where government regulation is minimal. [cont.]
