Data from Sept. 10, 1999

Based on an analysis of the same five very small searches used for the overlap analysis, this table shows the number and percent of unique hits for each search engine. Unique hits were those URLs that were found by only one of the thirteen search engines. Times refers to how many times in the four searches a unique hit was found. Northern Light found unique hits on each search.

Given these results from this very small sample, Northern Light found the most unique hits (20), while Fast and Northern Light found unique hits on four of the five searches.

This example is from a total of 326 hits from four searches found by thirteen search engines. Of the 326 total hits, 140 were unique Web pages.
