For the ones which follow Comscore and Nielsen monthly data already knows maybe the 2007 trends. I have tried to put this data in order and to compare it. The resulted charts will illustrate: - the share of searches between search engines - the evolution in 2007 of searches per search engine The report is also in PDF format or directly on blog: Search Engine Trends And Share Of Searches In 2007. PS: This is the first analyze done in 2008 using the Comscore and Nielsen data (US Only).
Doesn't look like much has changed in 2007. Google still in the lead by-far with Yahoo trailing and the others fighting for the scraps.
