You can use TAP and/or TAP Programmatic to target a specific mid-roll ad marker (or markers) in your Omny Studio podcast. This is a two step process, where you first create or edit the ad markers in Omny, then target those markers in TAP (or TAP Progrtammatic).
Omny: Edit the mid-roll ad markers
In Omny, either create new mid-roll markers or click Edit on an existing mid-roll marker. (See Adding pre, mid or post-roll ad markers to your podcast episodes in the Omny user guide.)
In the Edit mid-roll ad marker window, add the tags that you want to target in TAP or TAP Programatic.
TAP: Target the Ad Markers
In your TAP flight, create a Content tag content targeting rule that targets the ad markers you added in Omny.
The content tags you enter in TAP must exactly match the ones you created in Omny!
TAP Programmatic: Target the Ad Markers
In TAP Programmatic, create a new Deal. Create a Content tag content targeting rule that targets the ad markers you added in Omny..
The content tags you enter in TAP Programmatic must exactly match the ones you created in Omny!
