FOR RANKINGS -
Rankings are incredibly diverse these days. You may be a national seller and have a rank of 5 in the United States but have a rank of 30 in Australia (Even if you are a world-wide seller). Ranks depend on so many factors its best to find articles and posts on the subject. An example, back links from sites outside of your country can influence a rank for a term from that residing country.
The best start is to know where your target audience resides and the best way to reach them. Obviously, if you sell locally, you would optimize locally and can set your location preference in Google's webmaster tools and register with Google Local.
My company sells to prospects all over the world. My site has every language available for a user to interpret information. For me, it's simply a matter of choosing which country I want to focus on that will provide the best return (besides the US).
FOR UNRELATED TERMS
I too am seeing so many junk sites that provide no quality to a visitor whatsoever (just keyword spam sites). What I have noticed for these sites, they are loaded with adsense ads.
I'm thinking, google ran a query in the last few months to SET all websites WHERE adsense is not null = BOOST RANKS
