Google AdSense is an ad-serving program that places ads that “make sense” –
specifically, that make sense based on relevant content, and assumptions about
who might be interested in that content. AdSense is an application of the broader
concept of Contextual Marketing. Contextual Marketing is just what it sounds like.
On a website about custom cars, you might have an ad for fancy wheels or car
care kits. On a website about off-roading, you might have an ad for durable truck
tires or spotlight rigs. A hockey site might advertise hockey sticks…and a tennis
site, tennis shoes. Contextual Marketing just means aligning the ad serving with
the context/nature of the website and its audience, the same way like items are
grouped in a store. And the “context” can be cut much finer than website level, it
can be page level, article level, and so on, so the ads always match the material
they are appearing near, and thus, appeal to the interest of the reader/buyer at
any given moment.
