Ever wonder just how people got to your site in the first place? I’m not just talking about "They came from Google". Deeper . HitTail is a site that tracks and records the phrase someone typed into a search engine and then clicks on your page in the results. It is invaluable for tracking what keywords people are using and what is working. As an example I recently used the OctoMom’s website as an example for a blog post. Her name is Nadya . I intentionally spelled her name correct in some places and incorrect in others. Using HitTail, I could see how many people reached my site only because they spelled it as Nadia .
