Ad sense & premium Ad sense explanation:
Contextual Advertising, Part 2 of 2: "Google has two programs for content publishers: AdSense for smaller publishers; and Premium for large ones. Ad Sense is easy for publishers to set up.
Susan's description of the process is as follows: '[Publishers] fill out a form. We [review] their Web site [for quality]. They log in, get a piece of code. They can choose different ad formats, customize the color [and background], and have access to [near real-time] online reporting so they can log in and see how much money they're making.'
Google works directly with larger publishers through the Premium Ad Sense program, and even offers a revenue share. In many instances, Google will actually buy the ad space on a CPM basis."
