Microsoft recently beta launched adCenter Analytics, a free analytics suite that offers standard site activity tracking (including number of visitors, the pages they viewed and where they originated)

Webmasters can apply to be accepted into the beta program. Once accepted, site
owners get started by creating a profile for the specific URLs they want adCenter to track. There's an option to have the tracking script automatically inserted into a page's source code or to do it
manually--and once the site goes live with the code, adCenter will start collecting data for analysis.
