Rank is a direct measure of how well a website is listed in the search engine’s results. While rank does not concern itself with whether or not a page even appears in response to some query, it does, in fact, indicate the location at which the page was listed in case of an appearance. The point to note here is that a listed page can only be said to have appeared in response to a query, but the position of the page can only be indicted through the rank it receives.
