Google AdSense provides a number of different programs for monetizing content, each of which works in a somewhat different way, as I’ll discuss in detail later in this chapter. You can deploy each of these different programs by clicking the AdSense Setup tab, which opens the Get Ads page shown in Figure 8-9.
The programs are:
AdSense for Content
AdSense for Search
AdSense for Feeds
AdSense for Domains
Video units
AdSense for Content is by far the most important program, with AdSense for Search a distant second. These two programs are similar in the sense that they are both utilized by website owners with content and traffic. In contrast, each of the other programs involves either specialized content (feeds, video, or mobile content) or a parked domain—so each of the other programs can be thought of as noncore, although they can present good opportunities for making money.
While the AdSense for Content and AdSense for Search are generally aimed at the same kind of web content, there are differences in the way the programs work. AdSense for Content places ads on your web pages, similar to the ad unit shown in Figure 8-10, and you make money when a site visitor clicks on the ad.
With AdSense for Search, you put a Google search box, like the one shown in Figure 8-11, on your site.
The AdSense search box displays Google search results when a user enters a query. These search results show relevant ads. You receive a portion of the revenue generated when a visitor uses your search box and then clicks on an ad from the search results page, such as that shown in Figure 8-12, returned by Google.
Adding to the power of the AdSense search program, you can use the SiteSearch option to search your site rather than the Web (see AdSense for Search Settings for details). You can also configure the AdSense search results page (whether searching your site or the Web) to match the look of your website.
