I like that they have an easy to use interface with great reporting capabilities for keyword research as well as overall analytics of our campaigns. They also offer good customer service which is very important when you are paying monthly fees! Nothing really comes across in my mind but if it's something specific then let me know so we can chat about your needs/concerns more specifically. Try them out - there isn't much risk involved because their prices aren't extremely high either. Tracking keywords performance over time to see how changes affect rankings or traffic acquisition from different channels such as organic vs paid ads etc.. The main benefit here would be knowing what type of content works best organically versus through other means i.e., google adwords pay per click advertising. This helps us find new ways to improve upon current methods without spending too many resources at once since each channel has its own strengths & weaknesses. It gives insight into where opportunities lie within certain niches rather than just relying solely.
