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 Google AdWords. AdSense has become a popular company in creating and placing banner
advertisements on a website, because the advertisements are less intrusive than most banners, and the content
of the advertisements is often relevant to the website.
M
any websites use AdSense to monetize their content; it is the most popular advertising network. 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 generate revenue with. To fill a website with

Google launched its AdSense program in March 2003 and made it public in June of that year. Some advertisers
complained that AdSense yielded worse results than adword since it served ads that related contextually to the
content on a web page and that content was less likely to be related to a user's commercial desires than search results. For example, someone browsing a blog dedicated to flowers was less likely to be interested in ordering
lowers than someone searching for terms related to flowers. As a result, in 2004 Google allowed its advertisers to opt out of the AdSense network.
By early 2005 AdSense accounted for an estimated 15 percent of Google's total revenues.
In 2009, Google AdSense announced that it would now be offering new features, including the ability to "enable multiple networks to
AdSense for Content
The content-based adverts can be targeted for interest or context. The targeting can be CPC (click) or CPM
(impression) based. There's no significant difference[11] between CPC and CPM earnings, however CPC ads are
more common. There are various ad sizes for available for content ads. The ads can be simple text, image,
animated image, flash, video, or rich media ads.
AdSense for Feeds
In May 2005, Google announced a limited-participation of AdSense for Feeds, a version of AdSense that runs on and 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."[12]
AdSense for Feeds works by inserting images inhto a feed. When the image is displayed by a 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 mobile content
AdSense for mobile content allows publishers to generate earnings from their using targeted
Google advertisements. Just like AdSense for content, Google matches advertisements to the content of a website — in this case, a mobile website. Instead of traditional JavaScript code, technologies such as PHP, ASP and others are used.
Criticism
o
help prevent click fraud, AdSense publishers can choose from a number of click-tracking programs.These programs display detailed information about the visitors who click on the AdSense advertisements. Publishers can use this to determine whether or not they have been a victim of click fraud. There are a number of commercial tracking scripts available for purch
Millions of webmasters and website owners depend on revenue generated from google adsense but the company can be dishonest and manipulative in reporting in that it provides estimates of revenue earned with a small disclaimer that the finalized earnings may be slightly lower than estimated. However, the amount deducted can be 50% or even 100% (deducted as "invalid clicks"), a gross manipulation of adsense publishers.
The payment terms for webmasters have also been criticized. Google withholds payment until an account reaches US$100, but many micro content providers[require a long time—years in some cases—to build up this much AdSense revenue. However, Google will pay all earned revenue greater than US$10 when an AdSense account is closed and not disabled. On the other side Google bills its customers (API users for example) monthly, in increments as low as a few cents.
Many website owners complain that their AdSense accounts have been disabled just before they were supposed to receive their first paycheck from Google.[Google claims accounts have been disabled due to click fraud or forbidden content, but have offered no proof of this] An automated email is sent to the publisher's owner which offers no reasoning, or options but a link to file an appeal.n theg email, Google states that "Because we have a responsibility to protect our AdWords advertisers from inflated costs due to invalid activity, we've found it necessary to disable your AdSense account. Your outstanding balance and Google's share of the revenue will both be fully refunded back to the affected advertisers. The revenue generated - whether legitimate or not - is taken, and all complaints are deferred
