The InsideAdWords blog today announced they are looking for more audio ads testers. Any of you who use AdWords may consider trying out this new ad medium.
In terms of feedback, the Audio Ads team has heard that beta testers like the simple and clean user interface and the targeting and reporting options. Beta testers also find the audio ad creation process easy and fast since it only takes them a few days to create their ads and launch their first campaigns (as compared to potentially weeks for traditional radio ads).
I’m not a big AdWords spender, so I’d not be of much use to them, but if you want you can sign up for the audio ads beta here.
