I tried to get a free 15 days trial but i couldn't. It may take a while till Yahoo makes it available again. I was wondering about their path explorer, it seems to be an useful feature

Now Yahoo bought Indextools web analytics business and technology as well as its Tensa R&D Kit subsidiary. With this acquisition Yahoo is intending to expand their powerful services designed to maximize its clients online with marketing efforts. Yahoo wants to give the most valuable and relevant insights and metrics for online campaigns that run across their entire network. The first who will benefit from this offer will be the small to medium business marketing on the Web with Yahoo.
