Possibly whatever "tool" you are using to count back links is NOT any sort of authority regarding the number of back links that Google is counting. You see something and you automatically believe that it must be 100% accurate? com'on!
this domaine have only 2 miserable dofollow backlinks without any PR however everubodu should know that a web page on a domain without its own links, ranking based on 301′d links. To be a dullard and state the obvious, rankings based on 301′d link are still rankings based on links, this is the answer
Only the thing is unique content and you are updating your content in time or this domain has involved in redirecting process.
Why do you say this domain has no backlinks? There are 22 links to the site, not counting the ones you've created here, one of which is on a PR3 page within a PR7 .GOV domain. More thorough checking would often reveal ready answers to SEO "mysteries".
lol so much dispute. Some say it doesn't have backlinks, some say it does. How about we all agree that it has unique content and some backlinks have been removed or he is sleeping with the CEO of google ^^
