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.
Google AdSense program offers more than one way of earning revenue from serving Google AdSense Ads. Though �Google AdSense for Feeds� is one of the more recent ways of advertising using Google AdSense Ads, it�s in no way less effective than the others. Here, Google places the Ads of the advertisers in the relevant feed articles (again, note the most important characteristic of the Google AdSense program comes into play here too i.e. �relevant feed� not just any feed).
The feeds are in the form of articles, headlines or summaries. These content formats allow the users to easily access the content from several publishers (content owners) at one place. This is achieved through feed aggregators like Bloglines etc. Again, Google Adsense uses its technology to determine what advertisements would be contextually suited for a particular feed. You get paid as the publisher of original content and hence make easy money. As for the readers, they as such get a rich experience because they can see the relevant advertisements with the content that they are interested in. Moreover, they can also choose the feeds that they want. Users can click the advertisements to visit the advertiser�s website and check if their products and/ or services are of any use to them. Of course, the Advertisers benefit too. They get targeted advertising which means only the really interested people get to know about their products and services (and hence there are more chances of a better conversion rate for sales).
Google AdSense is moving beyond the traditional text and graphical advertising to rich media, including interstitials, expanding ads and floating ads. AdSense began contacting publishers last week to be involved in the rich media limited beta test.

The campaigns will likely be site targeted, rather than contextual, but details on the actual implementation of these new ads are still under wraps. With these kind of top-secret beta tests, NDAs are often requirements before being accepted into it.

Floating ads are ads that either stay on top as the page is scrolled, or ones that “float in” from the side of the page to the center of the page. Expanding ads are those that require user interaction to expand, either with a mouseover or a click. Interstitials are perhaps the most interesting addition to this rich media beta, because they are a format that people love to hate, and that are often more annoying than pop-ups. You have likely stumbled across an interstitial ad - they appear when you click through to read a page, and before they will show you the page, you are bypassed through to a full page ad that you must view before seeing the actual content you were wanting, often by having to click a link on the interstitial ad page.

No further details are known about the new rich media beta test, but I will see what I can find out. I can probably safely say that this is an invite-only beta test to which only a small number of publishers were invited to. So emailing the AdSense team for an invite to this beta probably wouldn’t work. But the good news is that often beta tests are turned into features that all publishers can utilize, so if you are interested in implementing rich media through AdSense, keep your fingers crossed and it may be added in the future.

This is definitely a departure from the usual text ads as well as the image and Flash ads in standard ad unit sizes that AdSense usually runs. Rich media ads are usually associated with companies such as Fastclick, PointRoll and Falk eSolutions, so the fact that AdSense is making inroads on this territory is quite significant. If AdSense offered rich media to all publishers, it could really hurt competitor companies offering similar rich media ad formats because of the vast number of publishers that AdSense has.

And if AdSense did offer rich media to all publishers, they could easily add a new clause that would mean companies such as Fastclick and PointRoll would suddenly be competitive ads and not be permitted on the same pages as AdSense. Many AdSense publishers implement rich media ads to compliment AdSense, and as non-contextual, most of these ad products are well within the AdSense terms. But if AdSense decided to not permit rich media ads on pages also running AdSense or AdSense rich media style ads, this could mean that many publishers would drop competitor’s ads and just show AdSense… as well as those advertisers flocking to AdWords to get their rich media creatives showing through the AdSense program.

In terms of dominating the online advertising market, AdSense rich media could seal the deal to make AdSense the force to be reckoned with, by not only dominating the online text ad and graphical banner-style advertising, but in the entire online advertising market. Definitely a story to watch.
