As a small local business owner in a competitive industry, I am competing with mostly similar solo operators but also against a couple of "big guys" who rank #1 for almost every suburb in Melbourne(Aus) for the main KWs.
I'm a little cautious stating specifics, however the "few" businesses that constantly dominate organic results have exactly the same landing page on a different subdomain with only the suburb changed. At a guess I would say there are hundreds of potential suburbs they have a subdomain for that rank..
I don't know whether google consider this as funnelling or spammy or something else, but my question is should I bring this to the attention of google, and if so, how? Or do I focus my attention on my own website and wait for google to eventually notice the "black hat" sites?
I would love to list a few urls to give a better example but am concerned that might not be appropriate here unless approved by a moderator.
