Microsoft has announced that its analytics offering named Project Gatineau is ready for beta testing. Invitations are being sent to existing U.S. adCenter advertisers now but all advertisers can request an invitation to Gatineau.

Features include click and visitor tracking reports, marketing campaign reporting and conversion tracking, and even unique demographic and geographic information about site visitors. There are some interesting questions in the adCenter forums now. Here's a quick roundup:

• There will not be a standalone version of Project Gatineau in the near future.
• Gatineau will not work on Live Spaces pages as that system does not allow javascript on their blogs for security reasons.
• Multiple domains will be supported through multiple profiles - the maximum number of domains is in flux while the project is in beta.
