Pretty good job for Facebook SEO team. They currently are ranking #3 for Barack Obama. (if you take the News Universal Search results not into account).
Facebook is even ranking higher than the Whitehouse.gov page, displayed in highlighted red here.
It was brought to my attention when I saw this Tweet:
Obviously, with all the people who became a supporter of Barack Obama, are linking with their Facebook profile to this page. This means the page already has more than 5.5 million internal back links.
Now ad all the external press links and bloggers that link to the page, and you have a super SEO ranking machine...
