Google has launched a custom search engine today (October 24, 2006) called Google Co-op. Co-op enables a user to create and launch a customized search engine which includes just a few specific websites. This should make for an interesting competition between a crowd of other products which includes Rollyo, Eurekster Swicki and Yahoo Search Builder. According to the Financial Time report:
"Users of Google Custom Search Engine will be able to select the websites they want to be included in their searches, and add to this list in future by “tagging” websites they visit. Any searches will then return results just from that slice of the Google search index."
This launch does not surprise me as Google has been missing out on search growth in the hot vertical search market.
