n/a: not applicable.

Note that search engines that receive search results from the same
source still might rank those results differently. For example: Yahoo!, AltaVista and AlltheWeb all receive results from the Yahoo! database, which consists of paid-inclusion entries from Yahoo! Search Marketing and listings generated by the Yahoo! spider, Slurp’s, regular Web crawls. However, those engines utilize their proprietary algorithms when deciding which of the available database entries are the best matches for a given search phrase. Thus, a no. 1 ranking in Yahoo! will not necessarily ensure a no. 1 ranking with AlltheWeb or AltaVista.
