Make Money with Google AdSense

Google uses its 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 login. AdSense has become one of the popular programs that specializes in creating and placing banner advertisements on a website or blog, because the advertisements are less intrusive and the content of the advertisements is often relevant to the website. Many websites use AdSense to make revenue from their web content (website, online videos, online audio content, etc.), and 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 salespeople to seek out advertisers. To display contextually relevant advertisements on a website, webmasters place a brief Javascript code on the website's 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. Google has removed the policy of limiting AdSense ads to three ads per page. Now, Adsense publishers can place unlimited amount of AdSense ads on a page.

Google Adsense History

Google launched its AdSense program, originally named content targeting advertising in March 2003. The AdSense name was originally used by Applied Semantics, a competitive offering to AdSense. The name was adopted by Google after Google acquired Applied Semantics in April 2003. Some advertisers complained that AdSense yielded worse results than AdWords, since it served ads that related contextually to the content on a web page and that content was less likely to be related to a user's commercial desires than search results. For example, someone browsing a blog dedicated to flowers was less likely to be interested in ordering flowers than someone searching for terms related to flowers. As a result, in 2004 Google allowed its advertisers to opt out of the AdSense network
