+### Supplying App Content Data
+
+Occasionally, an app which embeds a webview might run Prebid.js. In this case, the app object is often specified for OpenRTB, and the site object would be invalid. When this happens, one should specify app.content.data in place of site.content.data.

 ## Segments and Taxonomy
 
 The [IAB](https://iab.com) offers standard content and audience taxonomies for categorizing sites and users. Prebid supports defining these values as first party data in `site.content.data` or `user.data` as shown in the examples above.
