I've gotta ask, I'm thinking of a new strategy to implement in the beginning of 2010. I'm looking at ranking well for some localized keywords and was wondering how well subdomains would do? My idea is this, subdomain.maincityrelatedkw.com. My ultimate long term goal is to get my main domain (non sub-domain) to rank for the main city keyword. While attempting to rank the subdomains for smaller cities/towns within the main city. Is this a wasted effort? Obviously it'd be nice to offset my costs tremendously by purchasing one domain vs. 20-30 individual domains. What are your thoughts? Has anyone had any experience ranking a bunch of subdomains from a specific domain? The opportunity is pretty good and I don't have a doubt that I can rank a domain for these keywords, but from a cost/management aspect I'd much prefer to use subdomains. Your thoughts?
