Sub-domains rock! I've been thoroughly testing this theory on [snip]. I've been building out sub-domain names for just about every webpage.
The conclusion is sub domain names are very effective at lifting your search engine positioning for niche products, less so for generic (highly competitive) search terms.
Take a Google search for a niche [snip] product like "[snip]", a webpage that is 3 pages deep into our website (with a homepage PR of 6) and we're still in the top 10.[snip - google search]
Even better still, if you are reaching a local market, like us - we're an Australian [snip]company - the results are even better. You can get a whole page of results. Take "[snip]" and of course, [snip]is 1st, but we've got 7 other webpages in the top 10.[snip - google search]
Hope that doesn't make me sound too proud, I'm new to the forum and wanted to make a contribution before I ask my own questions :-)
