About Google ads
As you browse the internet, use mobile apps, read your email, or shop online, you see ads. Google shows ads on Google products like Search, YouTube, and Gmail. Google’s ad network also shows ads on 2+ million non-Google websites and apps. It is one of many ad networks that personalizes ads based on your online activity.
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. AdSense is a participant in the AdChoices program, so AdSense ads typically include the triangle-shaped AdChoices icon. This program also operates on HTTP cookies. Over 14.3 million websites use AdSense.
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.
