Behavioral targeting is a technique used by online publishers and advertisers to increase the effectiveness of their campaigns. Behavioral targeting uses information collected on an individual’s web-browsing behavior, such as the pages they have visited or the searches they have made, to select which advertisements to display to that individual. Practitioners believe this helps them deliver their online advertisements to the users who are most likely to be interested.

Behavioral marketing can be used on its own or in conjunction with other forms of targeting based on factors like geography, demographics or the surrounding content. Examples of behavioral targeting in advertising targeting systems include: Audience Science, Predicta BT, AdLINK 360, Adaptlogic, Avail, Boomerang, Criteo, Leiki, nugg.ad, prudsys, Netmining and Wunderloop.

Behavioral Targeting allows site owners or ad networks to display content more relevant to the interests of the individual viewing the page. On the theory that properly targeted ads will fetch more consumer interest, the seller may ask for a premium for these over random advertising or ads based on the context of a site.
