comScore: Google Breaks 65% Market Share But Did Bing Grow Share?

comScore released its October 2009 search share numbers and Google has passed 65% search market share, holding 65.4% share in October, up 0.5% from the previous month. comScore also claims that Microsoft Bing also gained 0.5% share, reaching 9.9%, while Yahoo dropped 0.8% to 18.0% from the previous month.

Nielsen also released its October 2009 stats, showing Google has a 66.1% share, Yahoo has a 15.4% and Microsoft Bing has a 9.7% share. I was unable to find Nielsen’s September report (did they publish one?) but I did find their August report which showed Bing had 10.7% share. In this case, Bing actually decreased in share by 1%, according to Nielsen.

As we always say, looking at these search share reports month-to-month is not always a good indication of the competitive landscape. I am sure Danny will be publishing a more comprehensive report, aggregating all this data, and fleshing out the true look at growth and decline amongst the various search engines.
