Indications are that MSN's PPC search volume and spend is now passing that of Yahoo! Search Marketing.
MSN has been recognized for a while as the best converter of the 3 major PPC players, though their traffic has been lowest. It will be interesting to see if the quality of traffic stays consistent as their search volume grows.
Quote from this article.June 2008 was the first month when our MSN AdCenter spending exceeded our YSM spending. A milestone has been passed as YSM becomes our number 3. And it wasn't because MSN spending rose; it was because YSM spending sank. I almost feel sorry for this company when I look at how they have fallen. (But I'm not really sorry because I don't like spending money and because they brought it on themselves.) A few years ago, our AdWords and YSM spending were about equal. In June AdWords spending was 35 times YSM spending. Our YSM spending went from six digits per month back in 2005 to four digits in June 2008. Is the lower spending because we are getting fewer clicks, bidding on different keywords? No. It is almost all due to the collapse in price at YSM. The competitors in this industry realized the poor quality of traffic out of YSM and drove the bids down, down, down.
