Seems everyone is talking about the demise of yahoo lately.
Yahoo currently monetizes queries at about half of what Google does. Yahoo has a lot going for it.
1. Everyone in the affiliate marketing world knows that yahoo’s traffic converts far better then googles. It seems that people use google more to research and AOL/Yahoo to shop.
2. Yahoo currently doesn’t geotarget, this has deflated prices on many keywords. I’ve seen keywords that are 50% non usa traffic.
3. Yahoo’s current system is virtually impossible to use. Try adding hundreds of keywords and ads and you give up in fustration very quickly. Google lets ads run instantly, Yahoo takes 3 days if you are lucky.
If Yahoo gets their act together their Revenue per query will be significantly higher then Google in the USA.
