Understanding Google AdSense
By
S. Housley
Google AdSense allows webmasters to
dynamically serve content relevant advertisements on web pages. If the
visitor clicks one of the AdSense ads served to the website, the website
owner is credited for the 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 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 be viewed at:

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.
Channels
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. 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.
Optimizing
Google determines the content of the ads that are shown, webmasters serious
about earning revenue from Google AdSense can use the following guidelines
to optimize their website and ensure that targeted and relevant ads are
served. If Google's spider has not crawled the site and determined the
nature of the content, public service ads may be served. Public service ads
will not accrue any AdSense revenue if clicked. As a result Google allows
webmasters to designate alternate ads. Alternate ads allow webmasters to
utilize the ad space in the event that Google is unable to serve targeted
ads to the web page. By specifying an alternate image, HTML page, or ad
server the advertising space can always being used effectively.
1.) Web page content on pages that ads are
served should be static not dynamic.
2.) Ensure that the robot.txt does not prevent
the web page from being spidered. Robots.txt file's will need to be removed
or the following text will need to bedded to allow Google's content bot to
crawl the site: User-agent: Media partners - Google
3.) If the website contains frames, select the
‘framed page’ checkbox when generating the ad layout code for that website.
4.) The body of the page and title of the page
should contain contextual words that indicate a common theme on the web
page.
Revenue Earned
Although Google doesn't disclose the exact revenue share or percentage that
webmasters will earn, webmasters will receive a portion of the amount paid
for clicks on Google ads on websites.
AdSense Conclusion:
Overall, Google AdWords can provide great supplemental income to webmasters
with content sites. Implementing and maintaining Google AdSense program on a
content site requires very little effort and can often bring a steady stream
of additional revenue for webmasters.
