Sharing audiences between your sites enables 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 (like 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).
Prerequisite
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 (for example the same email address). It can be done by firing any of the following events:
- Login
- Signup
- Newsletter subscription
- Identify API
Sharing audiences
- Go to Audience Manager
- Click the menu icon
to the right of the audience. and then select Share audience. - In the Share audience dialog, select sites and apps to give access to the audience, and then click Save.
The audience is now available for targeting when you create a new campaign.
Targeting shared audiences
After 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.
