Neilsen Online has released search share rankings within the U.S. As expected, Google is leading the way with over 4 billion searches. Over half of those searches are shared while 37.9 searches were attributed per searcher. Yahoo! came in 2nd place with 1.2 billion searches, 17.7% of those were shared while there were 22.4 searches per searcher. The lesson here is that Google is till at the top of their game when it comes to search. Especially when you consider, that the figures of Yahoo combined with MSN/Windows Live Search still don’t compare to Google’s numbers.
