The Banner Ads channel tab is where you can see and control your banner campaigns. Banner campaigns are launched from either the main campaigns page, or, by putting a % towards banners in the Master-Budgets page where you can designate a percentage of the budget to each media channel. Once you do that from that page, the banner campaigns are automatically created here.
So what do you have to do here then? Here is where you manage your default ad creative. When a new campaign is created, it's automatically set up to run the default ad creative - but also, you can update the creative individually here for each campaign - for example you may have creative aimed at IT candidates to run in your IT campaign that's different from the Sales-targeted ads. This is where you can see and control all of that.
For job-based campaigns, geographic targets are created automatically based on the locations of the jobs themselves. Also, occupation targets are set up automatically based on the jobs. However, here you can also add custom targets by searching and selecting from the BlueKai database of ad targeting. For example, Military or Diversity targeting, targeting "Active Jobseekers" or any other target that aligns to your goals or your expectations for what targeting would align to your ideal candidates for any need.
