I have been building backlinks for a client. He has another guy redesigning his site. The site covers the entire US. He is making a new site for every state, thus 50 new sites. So it would look like this: City.keywordstate.com. The guy told my client that each new site should be on a different server, thus 50 hosting plans. I find this totally outrageous. My client is worried that he is being taken advantage of and I agree. Is there any legitimate reason that they should be on different host? Also the redesign guy is making a separate site map for every city in every state. So lets say Florida would have over 300 pages, each having it's own site map, thus 300 site maps. He says the benefits are "tremendous". Everything I have ever read says 1 site map per domain. Any insights would be helpful and appreciated.
