In November internet search engine rankings by comScore (NASDAQ: SCOR), Google (NASDAQ: GOOG) again lead the pack, with 5.9 billion core searches conducted -- a 58.6% market share of all searches in the internet. This was almost the exact same level as October.

Coming up a distant second (as usual) was Yahoo! (NASDAQ: YHOO) with market share of 22.4%. The next three were Microsoft (NASDAQ: MSFT) at 9.8%, IAC/InterActiveCorp.'s (NASADAQ: IACI) Ask.com at 4.6% and Time Warner's (NYSE: TWX) AOL at 4.5%. In November (a seasonally weak month for web searches), U.S. web searchers conducted 10 billion searches -- a 5% decline from October.

Do these rankings surprise any web surfer? They shouldn't -- Google continues to dominate internet searches and Yahoo!'s Project Panama -- although technically a job well done -- is probably too late to the party to put any significant pressure on Google. Microsoft's Live Search push has garnered it about the same market share as in the past (a decent third place). The power of first-mover advantage is quite evident in Google's placement, and I'd suspect it's not going anywhere soon.
