For those who have used both ,is there a difference in the conversions between the two. Right now im currently using Google Adwords ,and i have had a lot of success over the past year. I have not yet tried Yahoo PPC.
We've tried both for sure as well as every 2nd/3rd tier out there but we stick with google the vast majority of the time. Most the stuff we run is on very low CPCs and we have trouble making that work out on Yahoo. I've heard from time to time that you can pay more per click on average on Yahoo. We've seen that being the case once or twice but normally in the time it takes us to set up one campaign on Yahoo we can set up two on google and they'll work better so that's where we concentrate our 95%.
