When you join the Link Building Solutions Program, we will put you into one of three groups - either Group A, B or C. All websites that you add to your account will be in the same group so your websites will never cross link with each other. The groups are determined by what category your Web site is in and when you join the program. All three groups are formed so the groups will be as even as possible in terms of the number of members and category of sites (For example: websites in the financial category will be distributed evenly throughout the three groups).
Another example: if you are in Group A, the websites that will be linking to you will all be websites that are in Group C.
