Earlier this month, we reported about Google's promise to begin testing Google Audio Ads by the end of this year. Apparently, Google has lived up to the promise and Google Audio Ads sign up page is now available.
If you do not have any type of account with Google, the sign up page would lead you to 'create a Google account – audio ads.' After you have created an account, sign in link takes you to Google Audio Ads home page. However, it seems the home page is not functional as yet.
