Noticed some of my visitors come from this url: productads-manualpolicing.amazon.com - well, i know that the company i hired was doing some Amazon ads but they would mostrly come from amazon.com as a referral so what is this one?
It appears you are correct. But you're question is way outside the scope of this forum. This group is for AdWords related questions only. You might have better luck getting an authoritative answer in the Google Analytics forum.
Best of Luck!
