Sharing audiences between your sites allows you to target users on one site based on their behavior on a different site. For example, if you have 2 sites - a store and a blog, you can target content promotion related to women's shoes on your blog to users that belong to an audience of "Purchased Women Shoes" on your store. You can do this between any of your sites and apps.
Once an audience is shared with other sites, every midnight users in the audience are matched with visitors in the sites that the audience is shared with. They can only be matched if they have triggered an event with their identity (i.e. Signup, Login, Newsletter Subscription, or Identify API) in both sites, with the same identity.
Notice that they will be added or removed from the shared audiences every midnight (unlike regular audiences, which are updated in real-time).
Users must identify themselves at least once in each one of the sites (the site that shares the audience and the site that is being shared with the audience), with the same identity (e.g. same email). It can be done by firing any of the following events:
- Newsletter subscription
- Identify API
- Go to Audience Manager
- Click the ‘Share’ icon to the right of the Audience.
- Select which sites/apps will have access to the audience and click Save.
Once shared, the Audience will appear in the ‘Shared with me’ tab in the Audience Manager of the selected sites.
Targeting Shared Audiences
Once audiences are shared with a site, you will see a condition called "Shared Audience" in the targeting options of your campaigns. You can target users who belong (or do not belong) to the shared audience.
