My memory is that that the count Google Maps and Y Local (although maps.yahoo.com may be included in the yahoo numbers). Local searches on Google.com and Y.com are not counted in this particular report.
It’s most useful when comscore blends the results as they did in 2006 , so one can see the entire local landscape broken down… I guess that one is tougher to sell. Google and Yahoo were virtually tied at that time. It would be interesting to see that view again.
I don’t think there’s any mobile data in here at all, unless they can’t determine the source of the queries, which would be surprising. There’s only one source (iPhone/Safari) that’s doing any volume in mobile right now.
Based on this data, It looks like with Microsoft’s acquisition of Yahoo, Microhoo would become the market leader in Internet Yellow Pages market besting both YellowPages.com and Superpages.com with a 22.7% market share.
