"Very well done"
— Justin Tadlock What They Say

Can I track the number of plays or views for a sermon?

You can track statistics for the number of times a sermon has been viewed using Google Analytics. The statistics will be for the page, not the number of times the actual audio or video has been played. For that, you can use services like YouTube, Vimeo and SoundCloud, which keep track of the number of media plays for you. They also host and serve your media files which keeps your hosting account from exceeding any storage or bandwidth limits that your provider may have in place.
