This is a very good piece of information. One more thing that I'm interested to know is the criteria used for display of results. For example, if I type the words 'Digital camera', what criteria does Google use to display the first 10-15 results. Is it the one who pays them for indexing or something else. I'm surprised to note that it's not the big camera manufacturers like Sony, Nikon or Canon who find a place in the first page when, e.g. 'Digital camera' is typed on the Google bar.
Don't even think you can try to figure out Google's algorythim. There's at least 200 variable to it, with each one being weighted differently. Several things that most people know is that links pointed towards your site are weighted very heavily.
I'm sorry, but don't try to trick the search engines...it will get you penalized or banned by Google. If you're just trying to get ranking, it's likely that your site will be of little value to the reader. I was at a session last week with Matt Cutts of Google and Wayne Forester of Bing on the panel and they basically said you don't need ranking reports...spend your time on creating good quality, original content that is useful to your audience and the search engines will find you. Unfortunately, most websites aren't original content. They are just a rehash of information that has already been posted elsewhere. To create original content it takes work - such as going out and doing an interview or some investigative reporting. Most tactics to get ranking fast are short-lived and you will find your site penalized back to the supplemental index.
On another note: the Google algorithm just changed. It's call the Panda/Farmer update. Search for it and you'll find the details. Again, create great content that's relevant to your readers and you will have no problem ranking.
