GoogleGoogle Sites led the U.S. core search market in June with 62.6 percent of the searches conducted, followed by Yahoo! Sites (up 0.6 percentage points to 18.9 percent), and Microsoft Sites (up 0.6 percentage points to 12.7 percent).

Both Yahoo! Sites and Microsoft Sites have experienced gains due in part to the continued utilization of contextual search approaches that tie content and related search results together. For more detail on contextual searches, please read this post on the comScore Voices blog.

At Rank Magic, we’re changing our keyword ranking reports to focus on Google, Yahoo! and Bing alone. We’ve found that including other search engines tends to confuse our clients, and since the three top search engines account for more than 94% of all searches it makes little sense to worry about tracking the others.
