Yesterday, comScore released its “Search Share Report” for September. The chart, which reflects last month’s scores in comparison to August’s, shows that there has been very little change across the board. Google is up 0.7%, while Yahoo is down that same number. Microsoft is up 0.1% and Ask is down that same number; AOL shows no change at all. The press release states that “the September 2010 qSearch figures reflect the impact of Google Instant Search”. comScore’s blog does a very nice job elaborating on intricacies of their search activity measuring procedures.
They go on to explain that they have started “Powered By” reporting; Google’s share includes all searches with Google properties including AOL and MyWebSearch (Ask), while Bing’s includes all their entities plus Yahoo! Web, image, and video searches. According to “powered by” reports a total of 69.1% of organic search results came from Google and Bing accounted for 23.5% of organic results for the months of September.
