Buy it! I purchased Visitor Tracking just before the holidays - I installed it about 10 days ago...I had to upgrade to Tier 3 to get all the functionality - but it's worth it. This is the best visitor-tracking app I've used, especially as a small business owner. Visitor Tracking has eliminated my need to look at Google Analytics. (I have Google Analytics on my cell phone and track it about every few hours. It is cumbersome and hard to work with. I constantly have to hire someone when I need to work through a new conversion.) I added three websites to VT, created a conversion, and sent out an email to my list. It tracks my UTM sources, and I can see in real-time who is online. I have Top Pages, Top Sources, Top Countries, UTM, and UTM Medium. Easy one screen no trying to figure it out. This is an excellent software...sooooo easy to use. I am glad to support it, and it is my go-to website on a daily basis. I wish they had an App, but I'm sure that will be on their runway eventually (hopefully...)
