What is Audience Extension?

Audience extension is an application of behavioral targeting . Audience extension allows advertisers to target a premium site audience, which is often sold out, across other sites that belong to the same ad network. The extension process takes a known audience segment and catalogs various shared characteristics that can be used to target people who bear similarities and are therefore likely to become customers. Audience Extension techniques are also sometimes called “Lookalike Modeling”.
