8.3. AdSense Content and AdSense Search
Google AdSense provides two programs you can use to make money from your web content:
These are different programs and work in different ways. AdSense Content places ads on your web pages, similar to the ad unit shown in Figure 8-2, and you make money when a site visitor clicks on the ad.
Figure 8-2. A typical AdSense Content unit provides text ads with links; you get paid when someone clicks one of the links
With AdSense Search, you put a Google search box, like the one shown in Figure 8-3, 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 returned by Google.
To summarize, AdSense Content and AdSense Search are two very different ways to make money from your content, but both are lumped (a little confusingly) under the AdSense program umbrella; it's important to be clear about the distinction.
