I don't think that they provide some tool . You can try Google analytic to get little guidance for your site .
Google analytic is good for you to analysis your website, I do not heard about yahoo tool have similar role.
i heard they made one but I think the Google analytics tool is better the site to yahoo analytics is http://web.analytics.yahoo.com/
Yahoo's Index Tools looks pretty cool, but I did not know it was paid only. Too bad as Google needs a good competitor in the free analytics departments.
Yahoo! Web Analytics is currently being offered to Yahoo! Small Business customers who host e-commerce sites with Yahoo!, as well as to advertisers who work with Yahoo! Custom Solutions and Yahoo! Buzz Marketing.
I dont think its available to the general public for free yet? I heard it should be soon though but am not sure!
Having used both Google and Yahoo! analytics (our company has 2 Yahoo! stores), I can give my opinion of both. Yahoo! is nice because it gives "real-time" data. Unfortunately, the UI is so confusing that we can never find anything, and once we do we can never find it a second time. A lot of the reports are under really counter-intuitive categories. I haven't glanced at it in a while, even though the data is great. Google, however, has a great UI but has been giving us bizarre data. It's been a nightmare to setup in Yahoo! Stores and we finally had to pay someone to do it. Yahoo! auto sets up the Web Analytics, so there was absolutely nothing to do but push a button. Oddly, neither store gives the same results as Y!stores (very limited) built-in analytics.
