what do you want to track with Google Analytics? Facebook Page, or a custom application / tab pinned to a page?
I suppose you mean a Facebook Tab, because you can not track a Facebook Page with Analytics, you have to use Insights.
If you want to add Google Analytics to a tab, then the process will be different for each tool in which you can create custom tabs. Can you please share the URL to the tab, so I can look at it?
Or you can check the “Reach” section of Insights. There are numbers of visits to your Timeline and tabs. (it’s the last section on the bottom)
