The comprehensive data provided in their reports has proven very useful when analyzing a clients backlink portfolio to discover trends and assist in creating new SEO strategies.

Search Explorer provides additional capability. I can see which sites are ranking for the keywords in the niche I am researching. That gives me value in a number of ways.

I do like the most prominent features: Hugest index, lots of analysis options, etc. But the reason I like this platform is that they are constantly innovating: From releasing their own search engine (allowing us to understand search much better) to gamification components just a few weeks ago. They always have great features coming up!
