I agree, this has been my favorite program to date! I have tried so many tools and most are very expensive and/or disappointing. Market Samurai does pretty much everything that is important to me and only cost me $97 one time. I made that back in two months!
Market Samurai is great software but not free. You can also do Google analytics + SEOQuake combination and accomplish similar result if one doesn't want to buy any software.
Thank you for this post gjivan. I am also using this software and its doing fine for me. But now a days, due to yahoo site explorer being merged to bing, its actually become very difficult to believe only in Majestic SEO backlinks. Do you have any suggestions regarding this?
