Google Co-op - Search Contributing Community Debuts
Google Co-op is about sharing expertise. You can contribute your expertise and benefit when others do the same. Help other users find information more easily by creating "subscribed links" for your services and labeling webpages around the topics you know best.
Google Co-op is a community of organizations, businesses, and individuals working together to help improve Google search. The benefit to you as a Google user is new ways to quickly refine your searches to find what you're looking for more quickly. Check out the Google Co-op directory for a list of providers who have contributed labels and subscribed links that you can add to your Google search results.
