The free version is very useful to get started with. The ability to track campaigns, keywords and landing pages. The free version is great for getting started, but the paid version is where the real power comes in. The ability to track campaigns, keywords and landing pages is a great feature. I dislike the limitations on the free version. The free version has limitations with the number of pages you can see and the amount of data you can pull. Make sure to do your research and determine if the free version is sufficient. This is a great tool to help with keyword research and tracking campaigns. It's great to see the results of campaigns as they are running. It's also great to see if you are reaching your target audience.
