I have been developing a number of informational websites relating to the current deterioration of the real estate market. One one subject matter I have the .com domains for most major cities in the US, ie: newyorkwidgets.com, californiawidgets.com. I also have the domain for onlinewidgets.com. My question is this; if I develop a central site such as onlinewidgets.com and redirect the city domains to it, will the redirected domains be just empty space, never getting indexed or ranked. Should I consider development of the individual cities in order to have the search engines recognize them or should I just be happy to get the type in traffic that I receive from those domains. I get a fair amount of type in traffic from them now and traffic should increase as the real estate market tanks. Thanks.
