We've completed our Google Audio Ads Beta test and are in the process of rolling out access to Audio Ads to all U.S. AdWords accounts. Today, over half of all U.S. AdWords accounts have been given access to Google Audio Ads. And at the end of June, it'll be available to all AdWords advertisers across the country. As part of this roll-out, we've prepared a new resource as well as a special offer to help interested AdWords advertisers get started with radio advertising:

Beginner's Guide to Radio Advertising
AM and FM radio advertising may be new for many of our advertisers, so we've put together a Beginner's Guide that cover tips for launching a successful radio campaign. The guide offers information on the types of audiences you can reach, tips on what makes an effective ad, ways you can reach your target customer, as well as budget, tracking and optimization best practices. We'll be adding to this resource over time, so if you have questions about radio advertising not answered in our guide, please let us know.

Special Offer for your First Radio Campaign
To help kick-start your radio advertisements, we're excited to offer $400 in Audio Ads credits towards your first radio campaign. To take advantage of this offer, you must use the Google Ad Creation Marketplace, a directory of professional ad creation specialists who can help you create your 30 second ads, and launch your campaign by June 30, 2007. You can learn more about this offer here.

We hope you will take advantage of some of these resources to help you get started with radio advertising.
