Google held on to its commanding lead as the preferred search engine in the US in May, processing almost 60 percent of all queries filed, way ahead of its two closest competitors Yahoo. and Microsoft.
Google nabbed 59.3 percent of search queries, followed by Yahoo in a very distant second place with 22 percent and Microsoft's MSN with 12.1 percent, says market researcher Hitwise.
Google's continued stranglehold on this market is significant considering that in recent years both Yahoo and Microsoft have invested heavily in developing and improving their search engine technology and accompanying search ad networks.
Microsoft and Yahoo officials strain to put on a happy face whenever they are confronted with Google's dominance. Both companies are fond of saying that search engine technology is still in its infancy and that consequently an opportunity exists to unseat Google as leader.
Still, when month after month trackers of search engine usage come out with their latest studies and Google remains firmly perched at the top, these predictions inevitably sound like wishful thinking and forced optimism.
Compared with March 2006, the May figures from Hitwise show Google making a percentage point gain, Microsoft losing share by the same margin and Yahoo staying almost static.
The search segment is the largest of the fast-growing US online ad market, accounting for 41 percent of revenue and worth about $5.1 billion. Online advertising spending grew 30 percent in 2005 to US$12.5 billion.
