Other miscellaneous features

Members can make groups to join friends according to their wishes. Further, each member can become fans of any of the friends in their list and can also evaluate whether their friend is "Trustworthy", "Cool", "Sexy" on a scale of 1 to 3 (marked by icons) and is aggregated in terms of a percentage. Unlike Facebook, where a member can view profile details of people only on their network, Orkut allows anyone to visit anyone's profile, unless a potential visitor is on your "Ignore List" (this feature has been recently changed so that users can choose between showing their profile to all networks or specified ones). Importantly, each member can also customize their profile preferences and can restrict information that appear on their profile from their friends and/or others (not on the friends list). Another feature is that any member can add any other member on Orkut to his/her "Crush List" and both of them will be informed only when both parties have added each other to their "Crush List".

When a user logs in, they see the people in their friends list in the order of their logging in to the site, the first person being the latest one to do so.^[13] Orkut's competitors are other social networking sites including MySpace and Facebook. Ning is a more direct competitor, as they allow creation of Social Networks which are similar to Orkut's communities.

Orkut redesign

On August 24, 2007, Orkut announced a redesign. The new UI contains round corners and soft colors including small logotype at upper left corner. The redesign has been announced on the official Orkut Blog. By August 30, 2007, most users on Orkut could see changes on their profile pages as per the new redesign. On August 31, 2007, Orkut announced its new features including improvements to the way you view your friends, 9 rather than 8 of your friends displayed on your homepage and profile page and basic links to your friends' content right under their profile picture as you browse through their different pages. It also announced the initial related languages: Hindi, Bengali, Marathi, Tamil, Kannada and Telugu. Profile editing can take place by clicking the settings button under the user profile photo (or alternatively, clicking the blue settings link at the top of any page).

On September 4, 2007, Orkut announced another new feature. user would be able to see an "Updates from your friends" box on the homepage, where it's possible to get real-time updates when friends make changes to their profiles, photos and videos. Moreover, in case someone wants to keep some things on their profile private, Orkut has added an easy opt-out button on the settings page. Scraps were also HTML-enabled letting users post videos or pictures. On November 8, 2007, Orkut greeted its Indian users Happy Diwali by allowing them to change their Orkut look to a Diwali-flavored reddish theme. On April Fools' Day 2008, Orkut temporarily changed its name on its webpage to yogurt, apparently as a prank. On 2 June 2008, Orkut has launched its theming engine with a small set of default themes.^[14] along with the photo tagging has also arrived at Orkut.

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.^[8]

AdSense for video

AdSense for video allows publishers with video content to generate revenue using ad placements from Google's extensive Advertising network. AdSense for video display both InVideo overlay and text overlay ads.

XHTML compatibility

As of September 2007, the HTML code for the AdSense search box does not validate as XHTML, and does not follow modern principles of website design because of its use of

• non-standard end tags, such as and ,
• the attribute checked rather than checked="checked",
• presentational attributes other than id, class, or style — for example, bgcolor and align,
• a table structure for purely presentational (i.e., non-tabular) purposes,¹ and
• the font tag.²

1: using a table structure for unintended purposes is strongly recommended against by the W3C^{[citation needed]}, but nevertheless does not cause a document to fail validation — there is currently no algorithmic method of determining whether a table is used "correctly" (for displaying tabular data or for displaying elements, that get proportionally wider or narrower when browser window resizes in width without active client side scripting).
2: the font tag is deprecated but does not fail validation in any XHTML standard.

Additionally, the AdSense advertisement units use the JavaScript method document.write(), which does not work correctly when rendered with the application/xhtml+xml MIME type. The units also use the iframe HTML tag, which is not validated correctly with the XHTML 1.0 Strict or XHTML 1.0 Transitional DOCTYPEs.

The terms of the AdSense program forbid its affiliates from modifying the code, thus preventing these participants from having valid XHTML websites.

However, a workaround has been found by creating a separate HTML webpage containing only the AdSense advertisement units, and then importing this page into an XHTML webpage with an object tag.^[9] This workaround appears to be accepted by Google.^[10]

How AdSense works

This article contains instructions, advice, or how-to content. The purpose of Wikipedia is to present facts, not to train. Please help improve this article either by rewriting the how-to content or by moving it to Wikiversity or Wikibooks.

• The webmaster inserts the AdSense JavaScript code into a webpage.
• Each time this page is visited, the JavaScript code uses inlined JSON to display content fetched from Google's servers.
• 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. (More details are described in the AdSense patent.)
• 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.^[11][12]
• For referrals, Google adds money to the advertiser's account when visitors either download the referred software or subscribe to the referred service.^[13] The referral program was retired in August 2008.^[14]
• Search advertisements are added to the list of results after the visitor performs a search.
• 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.

Abuse

Some webmasters create websites tailored to lure searchers from Google and other engines onto their AdSense website to make money from clicks. These "zombie" websites often contain nothing but a large amount of interconnected, automated content (e.g., a directory with content from the Open Directory Project, or scraper websites relying on RSS feeds for content). Possibly the most popular form of such "AdSense farms" are splogs (spam blogs), which are centered around known high-paying keywords. Many of these websites use content from other websites, such as Wikipedia, to attract visitors. These and related approaches are considered to be search engine spam and can be reported to Google.^{[citation needed]}

A Made for AdSense (MFA) website or webpage has little or no content, but is filled with advertisements so that users have no choice but to click on advertisements. Such pages were tolerated in the past, but due to complaints, Google now disables such accounts.

There have also been reports of Trojan horses engineered to produce counterfeit Google advertisements that are formatted looking like legitimate ones. The Trojan downloads itself onto an unsuspecting computer through a webpage and then replaces the original advertisements with its own set of malicious advertisements.^[15]

Criticism

Due to concerns about click fraud, 'Google AdSense' has been criticized by some search engine optimization firms as a large source of what Google calls "invalid clicks", in which one company clicks on a rival's search engine advertisements to drive up the other company's costs.^[16]

To help prevent click fraud, AdSense publishers can choose from a number of click-tracking programs.^{[citation needed]} 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 purchase.

The payment terms for webmasters have also been criticized.^[17] Google withholds payment until an account reaches US$100,^[18] but many micro content providers^{[citation needed]} 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.

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.^{[citation needed]}

Google came under fire when the official Google AdSense Blog showcased the French video website Imineo.com. This website violated Google's AdSense Program Policies by displaying AdSense alongside sexually explicit material. Typically, websites displaying AdSense have been banned from showing such content.^[19] Some sites have been banned for distributing copyright material even when they hold the copyright themselves or are authorized by the copyright holder to distribute the material.^[20]

It has been reported that using both AdSense and AdWords may cause a website to pay Google a commission when the website advertises itself.^[21]
