You can use Audience Solutions to leverage the data and insights you and your advertisers have about visitors to your website or app to reach specific, custom audiences and increase monetization opportunities. For example, a visitor who frequently browses a site or app's business content could be categorized as a "business news junkie". Using this information, it's possible to deliver line items tailored to such users during later visits regardless of whether or not they're viewing business related content.
The segments record visits to Google Ad Manager tagged pages or apps based on a combination of four membership criteria that you define: frequency and recency of page views or app activities, membership expiration date, and interests through ad units or key-values.
You can work with your advertisers to target line items to relevant audience segments such as "sports enthusiasts" for sporting goods ads, "travelers" for vacation advertisements, or "fashionistas" for haute couture ads.
Targeting to such specific audiences provides a better advertising experience for site or app visitors and improves effectiveness for advertisers and publishers alike.
Keep the following in mind:
- Users included in audience segments are identified solely by random identifier numbers.
- Mobile advertising IDs like Android's AdID and Apple's IDFA are resettable identifiers set by a mobile device's operating system. Both Android and iOS provide a mechanism for users to indicate they don't want to receive targeted interest-based ads, which applications receiving the identifiers must comply with. Please see the applicable Android and Apple documentation for more information.
