Advertiser represents a company or individual that pays to promote their product or service within your podcast. It is one of the required fields needed in order to create a campaign in Ad Manager.
The Advertiser field serves two purposes:
Minimize ad clashing by selecting the appropriate IAB category to ensure that no two similar ads run back-to back (e.g. two bank ads)
Allow you to run impression reports across multiple campaigns at once that have the same Advertiser
You can create an Advertiser by selecting the "Advertiser" tab at the top and clicking on the blue "New Advertiser" button. After adding the name and website, please select the appropriate IAB categories that may apply to each advertiser. Click on the "Create Advertiser" button to complete the process.
NOTE: An Advertiser may have multiple categories that they fit under. Please take note to add as many relevant categories as possible in order to ensure that the Ad Clashing logic works as intended.
Ad Manager uses the IAB Content Category Taxonomy v1
Once created, you can edit an existing Advertiser by clicking on the name and then the "Edit" button in the lower right corner.
