If you are online advertiser, spreading your efforts accross major search engines is a good strategy. Some people go only to Google, some only to Yahoo ro MSN. If you spread your efforts among these search engines there is more chance that you will be able to reach out to more potential clients.
I'm using Yahoo's ppc now. I'm actually quite worry and concerned about Google's slap. No doubt Google's Adword allow us to get more traffic. But their restrictions and rules are quite tight too. I don't want to get myself slapped by them and forced to buy a new domain name.
The results are good. I couldn't imagine that I could get lots of traffic from long tail keywords too.
