    can you tell me algorithm used by Google search engine?
    The world-famous 'Page-Rank' algorithm.
    I am not sure what did the interviewer expected when he asked 'tell me the algorithm'.

    PageRank is the heart of Google's search technology, a system for ranking web pages developed by Google founders Larry Page and Sergey Brin at Stanford University.
    PageRank is a numeric value that represents how important a page is on the web. Google figures that when one page links to another page, it is effectively casting a vote for the other page. The more votes that are cast for a page, the more important the page must be. Also, the importance of the page that is casting the vote determines how important the vote itself is.

    Google calculates a page's importance from the votes cast for it. (i.e. the no. of incoming links to a particular page)
    PageRank is Google's way of deciding a page's importance. It matters because it is one of the factors that determines a page's ranking in the search results. It isn't the only factor that Google uses to rank pages, but it is an important one.
    I found a detailed explanation of the PageRank Algorithm here: #-Link-Snipped-#
    Could anyone explain it in a simplified format?
