MOUNTAIN VIEW, Calif.—Google Inc. has joined the mobile marketing playground with a wireless version of its AdWords service.
The Internet giant quietly launched the offering that allows AdWords customers to place marketing messages—including clickable links—in listings retrieved through Google’s mobile search service. AdWords customers can develop their own mobile advertisements and marketing campaigns, and can set daily budgets, establish scheduled marketing messages and pay only when consumers click the ad or call the business.
The U.S. offering follows April’s launch of a similar service in Japan. Google is working to patent a system for click-through ad placements that determines the type of device being used and automatically takes a user to a mobile Web site or places a voice call, depending on the phone’s capabilities.
