Of all the SEO reporting tools that I use, Raven Tools is the one I rely on the most.
Raven presents much of the same data that several other worthy resources offer. The big difference is in the customized reports that you can generate. This is a great plus for agencies and consultants who regularly report back to their clients.
To be honest, there isn't a thing that Raven Tools does poorly. If there's any negative to their vast toolset, it's that they provide TOO MANY reports from which to choose.
With a 30-day free trial, you'd be crazy not to check them out.
