I know we have discussed N number of times on this topic. But here is something very interesting. I am working on a very competitive commercial keyword. The top 10 sites are really powerful. I never thought i will be able to break in top 10 atleast for 5-6 month. My site is hardly 4 month Old. What I am doing these 4 months is adding unique content to my site like crazy. Piling up unique content in my site. I never create any backlinks to the site. Just unique contents. I never checked rankings till I experience some nice flow of traffic to my site. I checked my rankings and surprised to see my site in top 10. My site is dancing on the first page since last few days, not settled yet. But It is like impossible to have my site in top 10. No chance my site had because the top 10 sites have thousands of quality links compare to zero of my site. Now I am surprised, if it is possible to rank a site with content only, SEO hardly have any worth. I will double up the content and speed up the process and see if it can hit the #1. Lets see, will update you guys.
