HitTail Keyword Checker
I currently use a combination of statcounter and google analytics to track website visitors, both are great in their own ways, but it can sometimes be a little time consuming when tracking which keywords visitors are using when landing on my pages.
With this in mind I will spend next week testing out the free version of HitTail a tool which claims to be the only product that reveals in real time which keywords people use to find your website.
If it is as good as the reports I hear say, I will probably upgrade to HitTail Plus or opt for a custom quote, which appears to be the best option with the ammount of traffic I receive.
