I don't know why I hesitated so long with the purchase, although I really wanted a more comprehensive keyword tool. Because it generally has too few functions, for example compared to a tool like sistrix? Or because the SEO Analyzer seemed too simple in the test account? Forget it! Even though the SEO Analyzer doesn't really offer much in its current version, what it is supposed to do, everything around keywords, it does really, really terrific: Tracking keywords, compare with the competitors, showing the most important information of each keyword... You can tag keywords, and you get countless keywords suggested. And the number of keywords tracked per day is really outstanding compared to other tools. I wouldn't hesitate.
