Yahoo has launched a self-service set of tools called Gemini for mobile search and native advertising. Per a rep for the Sunnyvale, Calif.-based digital company, it believes a one-stop shop for the two ad units could make a difference in attracting brand marketers. Mobile search ads have been available for the last month via Yahoo Ad Manager, which CEO Marissa Mayer unveiled at CES in Las Vegas. Now, they've been coupled with the platform's 10-month-old native ads. Gemini will be available within the Yahoo Ad Manager platform. Yahoo is trying to catch up with Facebook and Twitter when it comes to grabbing mobile advertising market share. And grouping native with mobile search could make a lot of sense, as the two styles of advertising appear to be on a crash course.
