This tool is very useful because it has many sections to manage your site and your keywords, and not least, it gives you the possibility to perform a keyword analysis even with the free version. The best feature is that it is very simple to use. Review collected by and hosted on G2.com.

I can't appreciate all the features, because for now, I am only a free user, and what I have seen is satisfying. Review collected by and hosted on G2.com.
