Stats Rundown
01/06/2007
In addition to the recent news and rumours, a couple of people were more interested in the statistical side of things; and so here is a dose of search engine statistics for you! Courtesy of Dogpile which, for those of you that don't know, is a search engine that combines results from the four major engines (Google, Yahoo!, MSN, ASK) in an effort to bring you an aggregate ranking of each site. Dogpile has released a new "search overlap" study that found only 0.6% of a search engines' first page results (top 10) matched across all engines (in a study of over 12,000 queries). This is lower than the 1.0% it reported in 2005 when it last did the research.
Other stats include:
- The percentage of total results unique to one search engine was established to be 88.3 percent.
- On average, 69.6 percent of Google first page search results were unique to Google.
- On average, 79.4 percent of Yahoo! first page search results were unique to Yahoo!
- Only 3.6 percent of the #1 ranked non-sponsored search results were the same across all search engines for a given query, down from 7.0 percent in the July 2005 overlap study.
- For 22.8 percent of all queries Google did not return a sponsored link where Yahoo! returned one or more.
- For 9.9 percent of all queries Yahoo! did not return a sponsored link where Google returned one or more.
