I have heard from someone that this thing it is possible to be true. Example: If you want to increase your rankings for United States, you will have to buy hosting from them. Also another thing that i read, is that the type of the hosting matters, webhosting, vps, dedicated. It is said that dedicated hosting will get your rank better than any kind of hosting. Tell me if you agree. And why is this happening? Where i have read, it doesn't say so.
