If you're looking to measure your ScribbleLive content's performance relative to the rest of your website, you can add third-party analytics tracking (Google Analytics, Omniture, etc.) to your white label template page.
(Of course, ScribbleLive has its own built-in analytics that can offer even more insight into your content, your audience and how the latter interacts with the former.)
Example: Google Analytics
The Google Analytics tracking code needs to be installed in the head of the template page your white label references. (What is a white label and how do you set it up? Check this article.) If auto-updates are enabled on your white label template, you can add the tracking code and it will be reflected within 5–10 minutes when ScribbleLive scrapes your template next.
