| 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.
The website maintenance related to Adsense is very easy and
requires very little effort. Webmasters need only to insert a Google generated javascript
into the webpage 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 javascript calls
the ad from Google and will ensure that ads are served each time a visitor goes to the
webpage.
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 competitors ads from being
dynamically served on their websites.
Google provides a wide variety of ad formats, that
webmasters can choose from. Webmasters can select from a handful of preformatted text
boxes. 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 visitors location.
Advertisements containing content in English, French, German, Italian, Dutch, Portuguese,
Japanese, or Spanish are all available.
Channels
Googles recently introduced channels as a way to enhance
Adsense reporting.
When a channel is selected Google modifies the javascript
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 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 adds 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
can make sure that the advertising space is always being used effectively.
- Web page content on pages that ads are served should be
static not dynamic.
- 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:
Mediapartners-Google
- If the website contains frames, select the ‘framed
page’ checkbox when generating the ad layout code for that website.
- 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, 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.
