Definition: Google Co-op was a service that allowed people to contribute expertise by suggesting ways Google searches can be grouped, labeled and annotated for refined results. Users subscribe to a topic, and the topic's labels and annotations appeared with the search results. This aspect of Google Co-op is no longer available.
Google Co-op also allowed webmasters to create a custom search engine that draws from these refined results. This part of Google Co-op was more successful and was rebranded as Google Custom Search Engine.
Also Known As: Google CSE
