|AdSense program essentially allows approved websites to dynamically serve |
Google's pay-per-click AdWord results.
Website maintenance related to AdSense is very easy and requires very little
effort. Webmasters need only to insert a Google generated java script into the
web page or website template. Google's spider parses the AdServing website
and serves ads that relate to the website's content. Google uses a combination
of keyword matching and context analysis to determine what ads should be
served. The java script calls the ad from Google and will ensure that ads are
served each time a visitor goes to the web page.
Early on Google implemented a filtering system that allowed webmasters to
prevent a specific domain's ads from being served on any websites in their
account. Ad blocking meant that webmasters could prevent their competitor's
ads from being dynamically served on their websites.
Google provides a wide variety of ad formats to match the most suitable option
with a website. Webmasters can select from a handful of preformatted towers,
inline rectangles, banners and buttons. The ad boxes can be modified by
webmasters to resemble the website's color scheme. Examples of how different
the various text boxes and color schemes appear on similarly themed sites can

Ads can be geo-targeted based on the visitor's location. Advertisements
containing content in English, French, German, Italian, Dutch, Portuguese,
Japanese, or Spanish are all available.
Google recently introduced channels, enhancing AdSense reporting. When a
channel is selected Google modifies the java script to include additional tracking.
The additional tracking information allows webmasters to track a variety of
metrics across their sites. Channels can be used to measure performance on
various domains, differences in revenue with various ad sizes, or placement
