  Alan Bleiweiss: If Site A, Site B and Site C can all be valid, and valuable, and helpful to visitors on their own, as stand-alone offerings, then it is viable to link the way you describe. IF, however, you are looking to get multiple results where Site A and Site B both rank for the same phrases and you own both, that alone is toxic. Alternately, if you can`t honestly say that each site is valuable and unique enough in its own right, as a single site, that too is a problem.
