Google is rolling out a new service in the U.K. called AdWords Business Credit that gives credit to small- and medium-sized businesses looking to boost their online ad spend with Google AdWords. This release follows a test drive of a similar service with 1,400 U.S. companies over the last year, although this remains the first commercial iteration of the credit solution. In the U.S., 74 percent of those using the pilot version of the “credit card” now use it as their primary payment method for AdWords. Additionally, the U.K. launch will be followed with more invitations to U.S. businesses.
