Google search ads appear primarily on te Google search engine (and might appear in google driven searches elsewhere)

The Google Ad Network, has many thousands, maybe millions of sites on which an ad using the ad network option may appear.

There is an option to select the specific sites or individual pages your ad will appear on, Google provides a list of likely placements.

Some sites will place ads on the checkout page of competitors foolish enough to insert Adsense ads on those pages, where money spending customers can be targeted.
