The Google Base blog announced the launch of the new Google Merchant Center. This is the location for you to “upload your feeds, check on the status of your items, and get information on the performance of your listings.”
The Merchant Center is replacing Google Base for those who submit products to Google. This new portal is designed around product listings and submitting data for product listings. Transitioning between Google Base and Merchant Center should be very easy, Google said they would automatically show your existing data feeds, items, FTP settings and other data in the new Merchant Center, based on your login.
Again, the Google Merchant Center replaces Google Base for anyone who uses Google Base to submit product data to Google. For anyone else, submitting anything else, stick with Google Base.
Plus, there is a new Google Merchant Blog.
