In a lot of ways behavioral targeting is doing to large web publishers what large web publishers have done to newspapers. It’s offering an opportunity to get the same audience more cheaply. A recent BusinessWeek article highlighted how big this discount can be, citing reduction of $60 to $3 CPM, a 95% savings, as a plausible example.
Who provided the discount? Behavioral targeters. Who paid for the discount? The sales team who lost the $60 sale. Behavioral targeting let the advertiser reach a targeted audience, but on cheaper real estate through a process called re-targeting. Re-targeting is a process by which a behavioral targeting company can mark a web user when they visit participating websites, and then use that web history to target the user in the future. For example, if you want to reach BusinessWeek readers, the behavioral targeter would mark users who visit BusinessWeek.com. The targeter could then serve ads to those readers when they visited other web properties at a significantly reduced premium. Ergo, ‘premium’ audience, bargain prices.
Granted, there’s still some inherent value in an advertiser’s ads showing up on a premium publisher’s site, but behavioral advertising just nibbles away at that value by separating the publisher and the audience.
