My website is on page 1 using market samurai but not really on page 1 in Google?

I have just seen this. My website is nowhere near page 1 in google search but when I used market samurai on SEO competition I see my site on rank 6. Can someone explain me how this happen? Also I have been building lots of back links like Social bookmarks, web 2.0 profiles, bookmarks, forum profile, blast those tier-1 with scrapebox but I see no backlinks at all in my site using Market samurai, there is no backlinks also using other tools. Am i doing something wrong?

Any answer/advice will surely be appreciated.. Or I am asking the wrong question here?

I dont believe in the stats provided by market samurai.

You will get different results if you are logged into a google account than if you are not. Try it both ways with clearing your cache and cookies first.

Try from other PCs or other browser, even ask someone to do a search operation for you from its pc.
