Link tagging is when you add various ?variable=value parameters to the link you use in an email newsletter, a banner ad or AdWords (which are autotagged now). The variables are campaign names, source, medium and others, which lets you track ROI of your non-indexable campaigns with Google Analytics. (Learn more about link tagging for Google Analytics here.)
Naturally, if you place such a link on your site as an internal link, it'll be considered as a different URL and will have its own link value.
The question I have is, since Google knows it's a Google link and knows the original URL (by stripping the tags), does it pass link value to the original URL? In theory, Google is able to do it, but practically, they might've not implemented this in the algorithm yet.
Do you have any knowledge/experience with this?
