In a Search Engine Watch Forums Thread, AdWordsRep, the official Google AdWords representative for the forum, called radio ads magical.
The thread is a discussion on if one should try Google Audio Ads or not.
AdWordsRep comes in and says this:
I have to say that radio has always held a bit of magic for me. There is just something about 'hearing your name' on the radio that is too cool for words. Way back in the day I won a minor radio contest (over the phone between songs) and waited with huge anticipation to hear my name actually announced. It was such a big deal - and I can still remember exactly how it felt. I can imagine feeling that same way being a small business advertiser hearing my own ad while on the road, coming home from work. So, for me at least, 'simple' audio has a lot of power.
Yes, I know I am spinning this story, but sometimes a blogger needs to have some fun. There is indeed something special magical about being on the radio. But there is no magic to the metrics you get from search ads - it is pure analytical (outside of some of the copy-writing, I suspect - but then there you have A/B testing).
