Online advertising

AdSense by Google

AdSense is an advertisement application run 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. Google beta tested a cost-per-action service, but discontinued it in October 2008 in favor of a DoubleClick offering (also owned by Google).

Google uses its Internet search technology to serve advertisements based on website content, the user's geographical location, and other factors. Those wanting to advertise with Google's targeted advertisement system may enroll through AdWords. 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.

Currently, AdSense uses JavaScript code to incorporate the advertisements into a participating website. If the advertisements are included on a website that has not yet been crawled by the Mediabot, AdSense will temporarily display advertisements for charitable causes, also known as public service announcements (PSAs). (The Mediabot is different from the Googlebot, which maintains Google's search index.)

Many websites use AdSense to monetize their content. AdSense has been particularly important for delivering advertising revenue to small websites that do not have the resources for developing advertising sales programs and sales people. To fill a website with advertisements that are relevant to the topics discussed, webmasters implement a brief script on the websites' pages. Websites that are content-rich have been very successful with this advertising program, as noted in a number of publisher case studies on the AdSense website.

Some webmasters invest significant effort into maximizing their own AdSense income. They do this in three ways:[citation needed]

They use a wide range of traffic-generating techniques, including but not limited to online advertising.
They build valuable content on their websites that attracts AdSense advertisements, which pay out the most when they are clicked.
They use text content on their websites that encourages visitors to click on advertisements. Note that Google prohibits webmasters from using phrases like "Click on my AdSense ads" to increase click rates. The phrases accepted are "Sponsored Links" and "Advertisements".
The source of all AdSense income is the AdWords program, which in turn has a complex pricing model based on a Vickrey second price auction. AdSense commands an advertiser to submit a sealed bid (i.e., a bid not observable by competitors). Additionally, for any given click received, advertisers only pay one bid increment above the second-highest bid


AdSense for Feeds
In May 2005, Google announced a limited-participation beta version of AdSense for Feeds, a version of AdSense that runs on RSS and Atom feeds that have more than 100 active subscribers. According to the Official Google Blog, "advertisers have their ads placed in the most appropriate feed articles; publishers are paid for their original content; readers see relevant advertising—and in the long run, more quality feeds to choose from."[7]

AdSense for Feeds works by inserting images into a feed. When the image is displayed by a RSS reader or Web browser, Google writes the advertising content into the image that it returns. The advertisement content is chosen based on the content of the feed surrounding the image. When the user clicks the image, he or she is redirected to the advertiser's website in the same way as regular AdSense advertisements.

AdSense for Feeds remained in its beta state until August 15, 2008, when it became available to all AdSense users.


AdSense for search
A companion to the regular AdSense program, AdSense for search, allows website owners to place Google search boxes on their websites. When a user searches the Internet or the website with the search box, Google shares any advertising revenue it makes from those searches with the website owner. However the publisher is paid only if the advertisements on the page are clicked: AdSense does not pay publishers for mere searches.


AdSense for mobile content
AdSense for mobile content allows publishers to generate earnings from their mobile websites using targeted Google advertisements. Just like AdSense for content, Google matches advertisements to the content of a website — in this case, a mobile website.


AdSense for domains
Adsense for domains allows advertisements to be placed on domain names that have not been developed. This offers domain name owners a way to monetize domain names that are otherwise dormant. Adsense for domains is currently being offered to some users, with plans to make it available to all in stages.

On December 12, 2008, TechCrunch reported that AdSense for Domains is available for all US publishers

Enhance your site—and your profits.

Keep your users coming back with contextually targeted ads.

You want to make more money from advertising, but you don't want to serve untargeted ads to your users. Google AdSense™ solves this problem by automatically delivering text and image ads that are precisely targeted to your site and your site content—ads so well-matched, in fact, that your readers will actually find them useful.

Access thousands of advertisers with minimal effort.

Signing up and maintaining relationships with advertisers is a full-time job. Luckily, Google AdSense does it for you. Our advertisers range from global brands to small local companies, in categories ranging from Education to Travel, Mortgages to Patio Furniture and just about everything in between. Best of all, once you get started, the AdSense program requires virtually no maintenance.

Rev up your site's revenue potential.

When you display Google ads on your website, you'll be maximizing your revenue potential. Google places relevant CPC (cost-per-click) and CPM (cost per thousand impressions) ads into the same auction and lets them compete against one another. The auction takes place instantaneously and when it's over AdSense will automatically display the text or image ad(s) that will generate the maximum revenue for a page -- and the maximum revenue for you.


When your content changes, so do your ads.

Google AdSense technology goes beyond simple keyword or category matching. We work hard to understand your content and deliver ads that are relevant to specific pages, automatically, no matter how many thousands of pages your site may have, or how specialized or broad your content. As your content changes, Google's ads change to match. And since our ads are also targeted by country, global businesses can display local advertising with no additional effort.*

Safeguarding your business standards is our business too.

We're committed to maintaining our customers' business standards. That's why Google AdSense features these safeguards:

Competitive ad filters. You can block competitive ads, or other ads you want to keep off your site, simply by telling us which URLs to block.
Ad Review. Before ads appear on your site, they're reviewed using a combination of human and automated processes. The review process takes into account a variety of factors, including the quality of the ad and whether it's suitable for all audiences.
Sensitive content filters. At times, certain ads may be inappropriate for some pages. For example, Google automatically filters out ads that would be inappropriate on a news page about a catastrophic event.
Choose your own default ads. In the unlikely event that Google is unable to serve targeted ads on your page, we offer you the option of displaying a default ad of your choice. This ensures that your advertising space is always being used as effectively as possible.

Customize ads to complement your site.

You spend lots of time perfecting your website's look and feel, and we want AdSense to fit in. So we let you customize the appearance of your ads to fully complement your site by choosing from over 200 colors and 24 pre-set color palettes (you can create and save your own custom palettes using a simple point-and-click color selection tool.

Track your earnings with online reports.

With AdSense, you can monitor your ad performance with customizable online reports that offer details like the number of page impressions, clicks and click-through rate. You can track the performance of specific ad formats, colors and pages, and spot trends quickly and easily. Our flexible reporting tools let you group your pages however you want, so you can gain insight into your earnings by viewing results by URL, domain, ad type, category and more.

And best of all, of course, you can check your earnings anytime.

Getting started is fast and easy.

Getting started as a Google AdSense publisher is easy. It only takes a few moments to apply online for both content and search ads. Once you're approved, simply log in to your account, copy a block of HTML code and paste it into your existing ad server or any of your web pages. And that's it—you're done. Relevant ads start to appear on your web pages, and your earnings start to add up.
