ComScore has released its search engine rankings for November 2010 and Google was the leading site once again with 66.2 percent of explicit core searches in the U.S. conducted on its site.

It's the third month that of comScore's survey in which Google has had its predictive search feature called Google Instant implemented. Google was once again the top search engine last month by a huge margin.

ComScore said in October that when people type something into Google, hit "enter," and then click on a link, it counts that activity in its "explicit core search" results. Results that show up in Google Instant as someone types will be included in "total core search" results if a user pauses on that for at least three seconds, comScore said.

Out of 16 billion total core searches, Google captured 10.6 billion. Google also accounted for 11.4 billion of 17.8 billion total core searches, which include Google Instant.

Trailing behind Google was Yahoo in second place with 16.4 percent of explicit core searches, and Microsoft's Bing was the number three in explicit core searches with 11.8 percent. Ask.com was fourth on the list with 3.6 percent and AOL was fifth with 2.0 percent of explicit core searches.

The order was the same as far as total core searches went for November. Google captured 64.3 percent, Yahood had 19.3 percent, Bing took 19.3 percent, Ask had 3.3 percent, and AOL brought up the rear with 1.8 percent of total core searches.

p>Earlier this fall, Yahoo complained that including Google Instant in search market share reports was "misleading," but the company recently introduced its own Google Instant-esque product known as Yahoo Search Assist.
