Aujourd'hui, Yahoo a annoncé le lancement de sa plateforme de publicité Panama :

Today Yahoo! announced the launch of its new ranking model, which will improve the way in which ads are ranked on Yahoo! Search. Unlike the old system for ad ranking, which was essentially a “pay for placement” model, the new model takes into account both advertiser bids and ad quality, including user click feedback, resulting in ads that are more relevant to a user’s query. What does this mean to you? When you search on Yahoo! you will see an improved search results page with more relevant ads that makes it easier for you to find exactly what you want.
