About IAB Contextuals

IAB contextual targeting is based on how a publisher self-categorizes its content for IAB. You can create segments using IAB categorization to meet your targeting needs. You can then target those segments in line targeting using either “target” or “block” logic.


To access IAB contextuals, enable them at the seat level using the Vendor Store. See Vendor Store.

IAB contextual targeting can either Target or Block the selected categories.

  • Select categories where you want your ad to serve, and Target them on the Targeting page.
  • Select categories where you don’t want your ad to serve and Block them on the Targeting page.
