The tracking java-code sometimes shows two tracking codes, one for user tracking (mine, correct), one for site tracking (something else).
If I browse on "my" pages, both codes show up. This is not limited to one URL, so I'm not quite sure which to register with google for the tracking.
['b._setAccount', 'UA-XXXXXX'], <--- my tracking code
ga('create', 'UA-YYYYYYY', <--- something else
