Spyfu is a game changer for someone interested in search engine marketing. My favorite features are #1 Being able to see what other sites are both ranking for and keywords they are bidding on along with their ads. #2 being able to organize each marketing campaign into projects, this tracks your keyword rankings, organized desired keywords into groups, and helps you stay organized with networking and outreach too. #3 Keyword research features are amazing. #4 Best customer support around. I totally recommend using Spyfu

100% Easy to use. Thorough explanation videos of features. They do an excellent job of communicating and adjusting based on our needs. They are always willing to track additional keywords that are niche specific.

Honestly, the customer service. I forgot to cancel my membership after I was finished with the software. It took about 2 minutes for them to void my charge.
