When I preview an answer from the administration console, does that action get counted in reports, such as Answers Viewed, Service Summary and Session Tracking?
No, previewing an answer through the administration pages does not get counted in the reporting statistics. This includes the Answer Display Total Pages in the Session Tracking Report, the Hits and Answers Viewed columns in the Service Summary Report and the Answers Viewed column in the Answers Viewed reports.
