Google Products Research Tools??

[AHH888]

Does anyone know of any google products research tools? I am trying to find what attributes and classifications my competitors are using? Much help appreciated. Thanks!

Done a bit of googling on this but can't find any suitable tools.

The only approach I can think of is to attempt to guess the URL of the product feed e.g. http://www.websitename.com/googlebase.xml. Obviously this is a bit of a long shot!
