Dive Brief: 

• Google announced officially Tuesday that searches on mobile surpassed desktop searches. In 10 countries, including the U.S., mobile search now makes up more than half of all Google searches.
• To respond, Google is offering new search ads and targeting hotels, automakers, and retailers. 
• New ads include a carousel style that can rotate photos, one-click hotel booking, and an ad that lists nearby stores. 

Dive Insight: 

While it's no surprise that searches on mobile surpassed desktop, it still produces challenges for Google and its advertisers. The smaller screen means stiffer competition for space so the top-of-page ads Google is offering are essential. The sales funnel is disintegrating as people move from device to device — changing the rules of targeting. Options like a one-click sale could help combat the loss of the funnel.
