Search Engine Rankings: October 2009
More than 10.2 billion US searches were conducted on the top search engines in October 2009, with 66.1% of them taking place on Google, 15.4% on Yahoo and 9.7% on Bing, according to new MegaView Search data from The Nielsen Company.
Google, with 6.8 billion searches, continues as the top-ranked search provider. Yahoo, Bing, AOL and Ask.com round out the top five.
Though Nielsen has, in the past, provided information on growth trends and changes that take place month-over-month and year-over year, October’s data - including total searches, unique searchers, search share, and all other search figures - cannot be trended with search results prior to October 2009 because of recent methodology changes.


I am also interested in knowing what the % is for search engines in just the USA. Last I remember it was 71% Google.
thx
I believe Nielsen is missing very important search engines here. I know that Youtube has more searches than Yahoo. It does not matter whether Youtube is not a text search engine or, for that matter, that search is restricted to Youtube itself. The wide use of Youtube and the enormous quantity of material laid there makes it impossible to ignore. Especially when the “related topics” for the very same article are SEO and SEM. Would you undertake a major SEO campaign and ignore Youtube? Not me. The same holds true for Twitter, Facebook, and other social applications. Not every firm should be on all platforms, neither should statistics ignore them.
