    • Power Searching:Better Googling
      • When you start a search, the search is done in the Google’s index of the Web
      • Google’s program searches its index to find all the pages that contain your search terms
      • output of this process could be millions of web pages……..
      • Now the real challenge comes in…. Weeding out the irrelevant ones
      • Google filters the relevant pages using hundreds of parameters-
      • like, does the page includes synonyms for the keywords- if so it gets prominence;
      • if the search terms appear together that page gets prominence
      • If the title of the page contains the search term then the page is considered more relevant gets search; quality of the page (page-rank) etc.
      • Using these parameters Google ranks each of the pages and displays the results- the page with highest rank will appear first, then the one with second rank and so on…
