I'm trying to build some Web 2.0s as tier 1 for my Amazon-based money site, targeted at the US audience. Must I use United States IP to create the web 2.0s? Or I could create the web 2.0 from my country and link them to the money site? For example, my money site is targeting "best hoverboard" in Google US and i want to build 10 web 2.0 properties. Should I use a vpn with US IP to create the sites, or just create them with my country IP?
