ADSENSE:-
(all about adsense)
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 one of the popular programs that specializes in creating and placing banner advertisements on a website, because the advertisements are less intrusive and the content of the advertisements is often relevant to the website.
Many 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 display contextually relevant advertisements on a website, webmasters place a brief Javascript code 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 put significant effort into maximizing their own AdSense income. They do this in three ways:
- 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".
Google currently shares 68% of revenue generated by AdSense with content network partners, and 51% of revenue generated by AdSense with AdSense for Search partners.
On June 18, 2015 Google announced rebranding of AdSense with a new Logo
How AdSense works:-
- 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 created by its Mediabot crawler 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
- 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.
- For referrals, Google adds money to the advertiser's account when visitors either download the referred software or subscribe to the referred service.The referral program was retired in August 2008.
- 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 publishers 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. Such 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" aresplogs (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.
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 uploads itself onto an unsuspecting user's computer through a webpage and then replaces the original advertisements with its own set of malicious advertisements.
