I'm trying to choose between SerpBook, SerpBuddy and SerpFox. All of the prices are very similar (SerpBuddy being ~$5 more per month). They all have very similar features but none really stand out to me at first glance. I wish I could play around with a demo account or free trial of Buddy/Book (fox offers a free 10 kw account). Has anybody compared the three or have another tracker that I should be considering? If there were discounts / coupons available please let me know - I couldn't find any. Thanks in advance for your opinions!
