Following the recent changes in the way Google ranks websites in Google search for mobile users, the search giant claims that users in the U.S., Japan and other countries have shifted more than half their Internet searches to handheld devices from personal computers. The company has seen the change in 10 countries, according to Jerry Dischler, vice president of search ads, who will discuss the milestone at an event Tuesday for Google’s AdWords product lineup.

Google also unveiled tools to help advertisers highlight their services next to mobile-query results. The new ad tools include features specifically designed for industries using mobile to promote their products or services.

In automotive, mobile users can see a carousel of car images that show how a vehicle looks with different option. People looking up hotels can see a variety of prices and book the location through a partner service.

The company also unveiled a mortgage feature for its Google Compare service in the U.S. Prospective home buyers can now get information on interest rates, loan terms and fees.
