actually, i'm swimming in sales on google adwords, but I want to reach a broad yahoo audience. here's why. if anyone of you has a successful site that has been running on google adwords for the last year or so... just go and use a simple Statistics IP program within your cpanel. these tools will tell you which countries, websites, and ip addresses are hitting your landing page. i did this when I rand my google ppc campaign, and did this when I ran my yahoo overture campaign. the results showed that google search audience tends to be primarily american, while yahoo tends to be primarily international. with my product i've notice good users click & read, while yahoo users click & BUY. there are other small things i've noticed about my product. for instance it's keywords are MORE expensive on yahoo, but the returns/conversion is about 3 times more likely. if you are a serious Yahoo PPC guru and want to give my product a try just send me a pm.
