In episode 250 of Semantic Mastery's weekly Hump Day Hangouts, one viewer asked if one should use a VPN or a proxy to prevent footprint issues when using multiple Google accounts in one IP address.
The exact question was:
Hey guys, I have about 5 or 6 google accounts that I access from the same computer. Some are more personal but there are two that I would like to do more SEO on for business. Should I be thinking about a VPN or a Proxy to prevent any sort of footprint from the one IP address?
