Expandable Advertisements (Mar. 2009):
- Expandable ad is a new type of ad that can appear on the pages.
- Expandable ads are rich media ads that can expand beyond the original size of the ad unit, following a user-initiated action. This creates more real estate for the ad, allowing for more interaction from interested users. For instance, expandable ads may stream a movie trailer, show video game clips, or display various views of an item for sale.
- Expandable ads will be served as third-party ads and will be created by Google-certified rich media vendors for the top display advertisers in our network. And like other Google ads, you’ll earn based on whether the expandable ads on your site are priced on a cost-per-click (CPC) or cost-per-impression (CPM) basis. Keep in mind that you’ll generate earnings from CPC expandable ads when a user visits the advertiser’s landing page, and not when a user simply clicks to expand the ad.

AdSense For Domains (Dec. 2008):
- AdSense for domains allows publishers with unused domains to help users reach relevant information by presenting content on the domains.
- Only available for domain name registrars and domain name holders before.
- AdSense for domains program is available for all users now (from Dec. 2008).
- Users often type domains into their address bar or follow expired links leading to sites with no content. Instead of an “under construction” page or 404 error, AdSense for domains provides links, search results, advertisements and other content. To do this, we use semantic technology targeted to the domain name. You earn revenue when users interact with the ads on your site.
- If you have a site that has content on it (e.g., articles, reviews, forums, blog postings or other text), then your site should be used with AdSense for content. If you have a page with no content on it, then AdSense for domains can help your users. To get started with AdSense for domains, check out our set-up instructions, or search or browse our AdSense Help Forum for more information.

AdSense For Feeds (Oct. 2008):
What is a feed?
A feed is a format that allows your content to be delivered (and subscribed to) on the web, often as headlines, summaries or articles. Users subscribe to feeds, often through a feed aggregator such as Bloglines or FeedDemon, which gives them access to all desired feeds in one location. This allows users to preview your content wherever they go, making it easier for them to find out what’s new on your site and reminding them to come back.
- AdSense for feeds allows web publishers to earn by placing targeted Google ads in their feeds.
- AdSense for feeds works the way the rest of the AdSense program works: by delivering ads that are relevant to your content and your readers.

What Is Coming Soon? – AdSense For Games
- Google began offering a limited number of online game publishers the opportunity to earn ad revenue by participating in a beta test of its AdSense advertising program for games on October 2008.
- Why games? The Yankee Group last year said that global advertising in video games reached $77.7 million in 2006. It predicted that figure will reach $971.3 million by the end of 2011. Such numbers, however, seem optimistic in light of the current global financial crisis.

“We have this amazing product called AdSense for content, where we’re monetizing the Web.” by Google CEO Eric Schmidt.

What Is Google AdSense?
- AdSense is an online advertising application developed by Google.
- Website owners can enroll in this program to enable text, image, and more recently, video advertisements on their websites.
- These advertisements are administered by Google and generate revenue on either a per-click or per-impression basis.
- Services: AdSense for Content, AdSense for feeds, AdSense for search, AdSense for mobile content, AdSense for domains, etc.

Business Plan?
AdSense has become a popular method of placing advertising on a website because the advertisements are less intrusive than most banners, and the content of the advertisements is often relevant to the website.
- For Google: Google uses the Internet search technology to serve advertisements based on website content, the user’s geographical location, and other factors.
- For advertisers: Those wanting to advertise with Google’s targeted advertisement system may enroll through AdWords.
- For webmasters: They use a wide range of traffic-generating techniques such as online advertising, SEO (Search Engine Optimization), etc, and they build valuable content on their websites that attracts AdSense advertisements, which pay out the most when they are clicked.

Google AdSense Growth?
Network growth indicates the revenue from Google AdSense. Blue color shows the revenue from the network. Base on the statistic, 80% of the network revenue is from Google AdSense. Even the Internet specialists predict that AdSense will be saturated in 2010 or 2011, we still can see around 6%-10% of the growth in the past two years.

How Does Google AdSense Work?
- The webmaster inserts the AdSense JavaScript code into a webpage.
- Each time this page is visited, the JavaScript code creates an IFrame with a src attribute set to the page’s URL.
- For contextual advertisements, Google’s servers use a cache of the page to determine a set of high-value keywords. If keywords have been cached already, advertisements are served for those keywords based on the AdWords bidding system.
- For site-targeted advertisements, the advertiser chooses the page(s) on which to display advertisements, and pays based on cost-per-mille (CPM), or the price advertisers choose to pay for every thousand advertisements displayed.
- Because the JavaScript is sent to the Web browser when the page is requested, it is possible for other website owners to copy the JavaScript code into their own webpages. To protect against this type of fraud, AdSense customers can specify the pages on which advertisements should be shown. AdSense then ignores clicks from pages other than those specified.

The Impact On E-Business?
- Google AdSense is a key element in Web2.0 service.
- Anyone can be the “broadcast” of AdSense.
- AdSense is the winner of network effect: 91.9% of search engine advertising market by Google and Yahoo!, and 75.6% by Google.
- AdSense’s partners brought 16.5 hundred million US dollars for Google in the first quarter of 2008 (37% of total revenue and 28% is from AdSense).
- Support new platforms with wireless service such as AdSense for mobile.
- Support multimedia content such as AdSense for YouTube

Conclusion
- Google AdSense brings the new fashion of life.
- Google AdSense generates extra income for SOHO.
- Keyword advertising (Google AdWords) and search engine marketing significantly change the old business model.
- They are Google, anything can happen.
