I have been thinking about this and would like other input. I will try to explain the best I can so everyone can get the idea. Lets say you own a site called 123cans.com and like most sites this one has many different categories. All the websites that I have ever looked at on the web, you click on the category and it takes you to a page under that domain. Lets say for this site, you have 3 categories (1 tin, 1 steel, 1 aluminum). Normally you would see in the address line something like 123cans.com/tin . My thinking is use a subdomain for each category so you would have tin.123cans.com . Looking at the way Google indexes subdomains, as each domain being a seperate entity in its own. This would mean that for every category you have, you have a seperate site and since all the sites are linked throughout each other in various ways, wouldn't that give you instant link popularity due to the reciprocal links within the site? You may remember not that long ago, Google had what they called a bad data push. A guy wrote a script that made endless subdomains to trap the googlebot within that domain and got top page rankings. I'm not suggesting this, but this problem has not been fixed within Google. Though my question is would this work as an honest way of generating link popularity somewhat instantly? This would also, since each category is considered an entity in its own, give you multiple sites. And since domains which seem to rank heavier than individual pages when indexed give one more draw on keywords in the search engines. In short I'm thinking of creating a site and I'm not sure if I should do it this way with the subdomains or just use individual pages. You thoughts on this matter please. Good or bad, all input helps. Thanks
