I just looked at yellow pages vs. internet ad spending stats this past week, and everything I am seeing has businesses abandoning yellow page advertising for online keyword search arrangements at an increasing rate.
Also, newspapers as we know them are in big trouble due to retail woes, but the trend is looking really raunchy for BLC, one I follow.
Also, as far as the yellowpages goes, I manage an ad budget for a small business and we recently dumped our ads with yellowpages.com and superpages.com in favor of google and yahoo keyword buys. So far, our click and inquiry counts are trending up. So I'm seeing some trends I personally like.
