Review on LinkStrategy by Jason Spainhour

The fact that it is an advanced tool with many features like content research, SEO audits etc.

It can be used by anyone who wants more out their tools than what they already have or just want something new for free which you get from all paid programs as well so no complaints here! I think there are still some things about this program which could use improvement but overall its worth using if you're looking into doing any kind of marketing work online. We've been able to improve our organic rankings since we started implementing Linkstrats recommendations.
