Yes, for each market/advertiser, the Segment Builder automatically stores an associated impression sharing contract that allows you to build audiences based on impression exposure.

To apply a re-targeting audience to an upcoming campaign, build out your audience in the Segment Builder—as you would with any custom segment—prior to the campaign launch. However, keep in mind that each user profile has a 30-day period to live in the Amobee DSP, starting from the day of exposure. Once the profile of an ad-exposed user has reached its 30 days in the Amobee database, you may no longer be able to retarget that user.

To target specific DMAs, Amobee partners with Digital Envoy to analyze the IP address received in a bid request. Amobee then uses the IP address in the impression event URL call to attribute impressions to locations.

For mobile devices, Amobee uses the latitude/longitude coordinates.

Amobee can retarget on desktop and mobile to users who were reached earlier on CTV (TV device) campaigns. You can set up a retargeting campaign on display and mobile line items, where the retargeting rule is to retarget the CTV line item impressions.

Yes, the device IDs of users exposed to DOOH ads can be used to retarget those users on other devices. The device IDs for a campaign would need to be requested from Vistar or Place Exchange.

The minimum setting permissible for geofencing on the Amobee Platform is 0.1 km or 0.1 miles.
