Free Website Content
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
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
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.
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.
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.
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.
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.
