Understanding
Google AdSense
Understanding Google AdSense
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.
