At first glance it looks similar to other SEM tools (SerpStat, SEMRush) but there are some surprising features in there including directory submission and blog reviews - not something I plan to use anytime soon, but the first tool I have to include this.

However, where this tool has come into its own for me is in the depth of their data. I pulled a list of backlinks for a bunch of sites, and unlike another tool I have a LTD for (I've mentioned it already) you get the FULL list of backlinks, not just the top 100. Same with keyword lists too. As long as you are realistic about the number of reports you are going to be able to run each month, this makes the tool worth the price on its own.
