How to use Signal Segments: Optimize Direct Demand
By using Signal Segments to assign predicted viewability and engagement scores as key values to each impression, you can more accurately target your direct line items to your best performing inventory.
Example: A buyer you are working with directly has requested that their ads only serve on 70%+ viewable inventory:
Within your GAM account, go to Delivery > Line Items and find or create the line item for this campaign.
Under Add targeting > Custom targeting > search and select sovrn-viewability is any of 0.7, 0.8, 0.9, 1.0.
Apply any other settings to the line item & save.
