Google Tales: Searching for directory sites: Google – Yahoo! questions “We began to notice in early March that Yahoo! pages seemed to be rising in Google search rankings. This was

there was any connection. But Yahoo!’s rankings kept rising in the succeeding months, and the announcement of
the Google-Yahoo! alliance naturally raised questions about the connection.”
