Yahoo customer service can't seem to grasp what a targeted ad is. I show them my adsense ads which are very well targeted and then compare them to the Yahoo ads. All they can respond is your ads are targeted to the category you chose in ad targeting. Ok, well what about context targted ads? The categories are way to broad to generate any sort of interest for people who woudl be at my site. My site is about 1 certain medical condition. When I choose the ad targeting category "Medical Conditions" I get ads for any and all medical conditions which my readers woudl not care about and thus no clicks. When I remove ad targeting I get Loan Offers and Credit Card. Very frustrating so far dealing with Yahoo.
