No. But, as days go by, Google gives preferences to search results randomization based on GRO location - thus presenting different results to different users based on their GEO location. I believe that in a couple of years from now, maybe less, their GEO coverage algo will be complete and we all focus, eventually, on gaining traffic from PPC networks since SEO is dying slowly.
Pay attention how Google invest a lot in destroying the SEO world, by:
1. Preventing us from watching the keywords referrals from Google analytics of Gmail logged-in users / and Chrome users
2. Positioning the Google places results up front
3. Presenting different results to different users
4. Making the search results more diverse to include results from Wikipedia, Youtube, and more
5. Giving us hard time when it comes to links building
6. Hitting our websites with Panda & Penguin
and so many more.
