hey, can you please give advance explanation about what you're talking about? So that anyone can give specific answer for your question
I believe he's asking if how do Yahoo! keep their ads like Google Ad-Sense, and how will he be able to join the Yahoo! Ads.
Its easy. Using yahoo for marketing is awesome and if you want to join, just go to google and search and get more information.
Yahoo Answers is beneficial in providing large amounts of targeted traffic to sites from each answer. Yahoo Answers is a great way to promote and advertise your site. Over 90 Million people use Yahoo Answers and thousands of people are guaranteed to see the answers provided. The majority of answers also become cataloged in important search engines such as Google and Yahoo.
Hi, I think you just want to know more about advertising on Yahoo (at least what I understand from the question...) Well to share my experiences Yahoo (Overture Network) is fine but the quality of the traffic is not that cool as Google at all. Hope this helps.
