Google AdSense allows webmasters to dynamically serve content relevant advertisements on web pages. If
visitor clicks one of
AdSense ads served to
website,
website owner is credited for
referral. Google's 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
web page or website template. Google's spider parses
AdServing website and serves ads that relate to
website's content. Google uses a combination of keyword matching and context analysis to determine what ads should be served. The java script calls
ad from Google and will ensure that ads are served each time a visitor goes to
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
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
website's color scheme. Examples of how different
various text boxes and color schemes appear on similarly themed sites can be viewed at:

Ads can be geo-targeted based on
visitor's location. Advertisements containing content in English, French, German, Italian, Dutch, Portuguese, Japanese, or Spanish are all available.
Channels Google recently introduced channels, enhancing AdSense reporting. When a channel is selected Google modifies
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. By assigning each group of pages to a specific channel and comparing results in custom channel reports webmasters can work at increasing their AdSense revenue.
