Introduction Founders: Larry Page and Sergey Brin Incorporated: September 4, 1998 Headquarters: Googleplex, Mountain View, California.
Why do we love Google? Size and scope: Now indexing over 20 billion web pages Relevance of Results: PageRank Diversity of Search: Image, News, Book Search, Scholar, Blog Search, Finance, Video . . . Other Tools: Google Maps, Picasa, Blogger, Gmail, Calendar, Docs & Spreadsheets . . .
PageRank PageRank explained by Google: Google interprets a link on page A going to page B as a vote -- by page A, for page B. Google looks at more than the sheer volume of votes, or links a page receives; it also analyzes the page that casts the vote. Votes cast by pages that are themselves "important" weigh more heavily. Page A Page B Page C Page D
But… We may love Google, however only a few users know how to use full search capabilities. I’m not getting what I’m looking for!!!
Basic Search How does Google interpret basic search? Google places “AND” and “OR” operator between all search terms entered in basic search box. You enter: news reader Google searches: news AND reader OR readers
