Google AdSense is a program run by Google that allows publishers in the Google Network of content sites to serve automatic text, image, video, or interactive media advertisements, that are targeted to site content and audience. These advertisements are administered, sorted, and maintained by Google. They can generate revenue on either a per-click or per-impression basis. Google beta-tested a cost-per-action service, but discontinued it in October 2008 in favor of a DoubleClick offering (also owned by Google).〔()〕 In Q1 2014, Google earned US $3.4 billion ($13.6 billion annualized), or 22% of total revenue, through Google AdSense.〔("Google Announces First Quarter 2014 Results" ). Google. Retrieved July 9, 2014.〕 AdSense is a participant in the AdChoices program, so AdSense ads typically include the triangle-shaped AdChoices icon.〔(【引用サイトリンク】About Google Ads )〕 ==Overview== Google uses its Internet search technology to serve advertisements based on website content, the user's geographical location, and other factors. Those wanting to advertise with Google's targeted advertisement system may enroll through Google AdWords. AdSense has become one of the popular programs that specializes in creating and placing banner advertisements on a website, because the advertisements are less intrusive and the content of the advertisements is often relevant to the website. Many websites use AdSense to monetize their content; it is the most popular advertising network. AdSense has been particularly important for delivering advertising revenue to small websites that do not have the resources for developing advertising sales programs and sales people to generate revenue with. To display contextually relevant advertisements on a website, webmasters place a brief Javascript code on the websites' pages. Websites that are content-rich have been very successful with this advertising program, as noted in a number of publisher case studies on the AdSense website. AdSense publishers may only place up to three link units on a page, in addition to the three standard ad units, and two search boxes.〔(【引用サイトリンク】title=AdSense Ad limit per page )〕 This restriction is not applicable for premium publishers who work directly with account managers at Google. Some webmasters put significant effort into maximizing their own AdSense income. They do this in three ways: # They use a wide range of traffic-generating techniques, including but not limited to online advertising. # They build valuable content on their websites that attracts AdSense advertisements, which pay out the most when they are clicked. # They use text content on their websites that encourages visitors to click on advertisements. Note that Google prohibits webmasters from using phrases like "Click on my AdSense ads" to increase click rates. The phrases accepted are "Sponsored Links" and "Advertisements". The source of all AdSense income is the AdWords program, which in turn has a complex pricing model based on a Vickrey second price auction. AdSense commands an advertiser to submit a sealed bid (i.e., a bid not observable by competitors). Additionally, for any given click received, advertisers only pay one bid increment above the second-highest bid. Google currently shares 68% of revenue generated by AdSense with content network partners, and 51% of revenue generated by AdSense with AdSense for Search partners. On June 18, 2015 Google announced rebranding of AdSense with a new Logo〔(Adsense rebrands with new logo ), ''Preview Tech'', June 19, 2015.〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「AdSense」の詳細全文を読む スポンサード リンク
