A thread at WebmasterWorld started by WMW Administrator Tedster asks Referer tell-tales for personalized search? Is there a way to track referrals from Google Personalized Search?
I do not know, the thread has very few replies and it looks like there is no easy way at this point.
Why does Tedster ask? Because personalized search is believed to be the future of search. And to get a handle and start tracking referrals and data on this technology, is a wise move for any SEO.
