Search Engine Statistics: Freshness Showdown
Data from May 17, 2003.
All search engines are pictures of the past, but which search engine has taken its picture most recently? This comparison tries to begin to answer that question and tracks how the search engines change over time.
Key points from results:
* On one search of the six, AlltheWeb continues to find several extremely old records (Sept. 25, 2001, Feb. 25, 2002, June 29, 2002, Dec. 24, 2002, and Jan. 2, 2003). If these were not included, AlltheWeb's oldest would only be 103 days old.
The graph below shows the distribution of pages by date. The methodology of this study attempts to identify the date the page was crawled, and those are the dates shown below. The graph should give some idea of the crawling pattern of each of the search engines.
Also, due to the non-random nature of the searches used and the small number of results, the points on the graph only give a broad, general idea of the age groupings of the databases.
Since the freshest search engines are so crowded at the top, here is another graph with a close-up of the five most current databases looking at the recent hits from about a month and a half.
