Google has announced a series of changes that are being made to the Webmaster Tools service, including a new interface and navigation system, plus subscriber statistics which can show RSS feed publishers the number of aggregated subscribers they have from other Google services, such as Google Reader and the personalised iGoogle search interface.

This comes on top of the recent changes made to the Webmaster Central landing page which provides website owners links to the range of services and tools being offered by Google to help manage and track site activity and performance. This includes Google Analytics and developer tools, as well as the range of gadgets that are available through iGoogle and Desktop Search which can also be added to webmasters' own sites.
