Web pages that change without the URL changing (single page apps) can be tracked. There are two ways to go about doing this.
Creating the Snapshot as you would for any other page. When you use this method, not all clicks can be placed on visual reports. Rather they tracked under our List Report
You can also use our Track by Name code and with the aid of your web developers place the code on your application where the new content renders. You would use our Page Camera tool (Capture Snapshots Manually Using Page Camera) to create the Snapshots for "page" specifying the Track by Name option in the configuration. This will provide you with more visuals on the reports.
