I'm using a VPN to log in internationally to view search results in certain countries. 1) What is the most optimal way to ensure that I'm not being tracked - set up virtual server and create my own VPN? (I imagine my MAC address is still being tracked despite using a VPN?). 2) Using a more popular VPN (which most good VPNs probably are), does Google "discount" Page Rank or disregard traffic from VPNs? Thanks very much in advance!
