I'm making a certain niche classifieds using Joomla. Its practically done and looking beautiful. but when I look at lets say craigslist, craigslist has their url's set up as for example [nameofcity.craigslist.org], and their meta name usually has the [name of city and category] in both the meta name and the page title. Is this a major screw up on my part? I know people will say classfieds may need marketing, but on a purely SEO basis, should I make a custom site? also, does having subdomains for each location help with appearing on google search results? My niche depends I believe mostly on a good SEO with location+category emphasis. What do I do?
