Google’s “Google Product Search” was renamed “Google Shopping”, introducing the auction model in the search of goods. The specific changes are as follows: 1, the product information presented by the lower part of the natural searching result page will be moved to the top of the page; 2, the result is no longer showed for free but decided according to advertisers’ bid. Google expected that this model adjustment will increase more than $ 1 billion for the Google each year. This adjustment is considered to be another extension of the auction model in Google. It is understood that the auction model has been widely used worldwide. The model derives from a macroeconomic theory, and a number of Nobel Economic Prize masters including Nash, Vickrey, and Myerson have studied in this area. In addition to the new revision of the “Google Shopping”, Google’s Adwords (Google’s auction ads) also use the auction model with the same standard. Customers can choose the keywords of triggered ads and specify the maximum amount that there are willing to pay for per click. And Baidu’s Promotion, Yahoo’s Panama, and Taobao’s Train also use this model. Looking at the traditional areas of media, print media, marketing, television advertising, auction of cultural relics and so on, we can find the examples of auction model are abound. In the minds of many people, “PPC” is equivalent to the price being the first, which is actually a misunderstanding. As pointed out by the president of Microsoft Online Services Group Lu Qi on the 2011 China IT Leadership Summit, “Any search engine cannot put who gives more money to in the top place. In this case, the search engine will lose users. Baidu, Google, and Yahoo all make the ad position according to user experience, clicks and other indicators. Customers’ paying for each click is only part of the factors.” In Lu Qi’s opinion, the business model of search engine must follow the principles of macroeconomics, treating optimizing the overall public welfare as the main target, and “PPC” regards the social welfare as the supreme criterion. “From this point of view, Baidu, Google, and Yahoo are the same.” This is the most important issue that search bidding model is facing foe a long time — how to make the user experience join the auction mechanism to improve the quality algorithm, to avoid malicious customer behavior and irrational auction. Currently, Baidu, Taobao and other companies have taken the lead in actively exploring and trying in these issues.
