Aug. 7 (Bloomberg) -- Facebook Inc., owner of the world's most popular social-networking service, unveiled a new mobile- advertising service designed to help software developers woo more users to their applications.
The service, which is being tested with a limited number of partners, will work with Apple Inc.'s App Store or Google Inc.'s Android market or Google Play, the company said on its developer blog. When users click on an application ad displayed on Facebook's mobile service, they'll be linked to the smartphone's online marketplace to download the app.
"We're announcing a new way for mobile app developers to grow their business with an ad unit that helps them reach and reengage their users," the company said.
Facebook, grappling with investor concerns about its prospects for growth, is trying to find new ways to make money from users who are increasingly accessing the service from mobile devices such as smartphones and tablets. The company started its first mobile ad service in March.
In May, Menlo Park, California-based Facebook said sales growth wasn't keeping pace with user expansion amid wider mobile adoption.
