It has been shown that YouTube was the third largest search engine in a presentation entitled, “Getting Found in All the Right Places,” at a SEMNE event on Nov. 7, 2007. YouTube was about to pass Yahoo! in expanded searches in a story that was published in Search Engine Watch on July 20, 2008. So,“YouTube has grown to become … the second most-used platform for searching,” is old news.
If anyone wants an update, here’s the U.S. data from comScore qSearch for May 2014: Google had 12.5 billion explicit core searches, YouTube had 4.0 billion search queries, Microsoft had 3.5 billion searches, and Yahoo! had 1.8 billion.
