The First few pages can be completely conquerable. Theory is the key to make this work for you.
Google Theory: Google will not give more than 1 spot per hosting IP minus a few exceptions.
You can see when I type in my forum address, I get the top heading. I also get a “most recent” plug for my site. Underneath I get 3 Spots from Digg.com which means that a few people have dug my articles. Digg ranks pretty high so be sure to pay attention in future posts. I get a twitter bump from an account that Retweeted my link. So at most 2 of these comes from the IP address of the computer that hosts my website.
The easiest way to take over multiple pages for a specific combination of keywords is similar .COMs hosted all over the web. Yahoo Hosting, Godaddy, HostGator, MSN, and Hundreds more.
This is completely blowing away the piano tuning market for as little as 75-100 dollars a month.
#1 Google Principle: Multiple hosted websites targeting the same keyword will easily take over more than 1 position on the front page.
