When you create a custom multi-issue viewer app for the iPad or iPhone, you can enable Social Sharing. You or your customers can choose an option in your viewer app to share the article through Facebook, Twitter, email, or copy and paste. This message includes either a link to the publication URL or to the article, depending on whether you protect the article. Anyone who clicks the article link on a computer can view the article contents in the Adobe Content Viewer for the Web (also called the Web Viewer) in a browser. Anyone who taps the article link on an iPad or iPhone can open or download the app and view the article.
Views of the shared articles on the Web Viewer are included in download fulfillment counts. For details, see Social media download counts.
