    • 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…
