Besides the clicks and the impressions, you can earn money by including a Google search box in your web site code. If your web site visitors use it you will get a percent of the profit relevant to their search terms. AdSense for Feeds and AdSense for Domains are also available . The first one places ads in the feeds managed by Google for your web site. The second one allows advertisements to be included for domains that do not open a web site with content. Bear in mind that making money with Google AdSense requires a popular site with popular keywords on it and attractive positions for the ad placements. Generally, the software is administered by Google and you can monitor your balance through your Google profile.The service is freely accessible for everyone who complies with the corresponding Terms of Use.
Overview:- 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. AdSense publishers may only place
up to three link units on a page, in addition to the three standard ad units,
and two search boxes. This restriction is not applicable for premium publishers
who work directly with account managers at Google.
Some webmasters put significant
effort into maximizing their own AdSense income. They do this in three ways:-
1.
They use a wide range of traffic-generating techniques, including but not
limited to online advertising.
2.
They build valuable content on their
websites that attracts AdSense advertisements, which pay out the most when they
are clicked.
3.
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. 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.
History:- Google launched its AdSense program, originally named
content targeting advertising in March 2003. The AdSense name was originally
used by Applied Semantics, a competitive offering to AdSense and then adopted
by Google after Google acquired Applied Semantics in April 2003. Applied
Semantics was started in 1998 by Gilad Elbaz
and Adam Weissman. Some advertisers complained that AdSense yielded worse
results than AdWords, 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 flowers than someone searching for terms related to
flowers. As a result, in 2004 Google allowed its advertisers to opt out of the
AdSense network. Paul Buchheit, the founder of Gmail, had
the idea to run ads within Google's e-mail service. But he and others say it
was Susan Wojcicki, with the backing of Sergey Brin, who organized the team that adapted
that idea into an enormously successful product. 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 display ads".In February
2010, Google AdSense started using search history in contextual matching to
offer more relevant ads. On January 21, 2014, Google AdSense launched Direct
Campaigns, a tool where publishers may directly sell ads.
Types:
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 between CPC and CPM earnings, however CPC ads are more common. There
are various ad sizes available for content ads. The ads can be simple text,
image, animated image, flash, video, or rich media ads. At most ad sizes, users
can change whether to show both text and multimedia ads or just one of them. As
of November 2012, a grey arrow appears beneath AdSense text ads for easier
identification.
AdSense for Search:- AdSense for search allows publisher to display ads relating
to search terms on their site and receive 51% of the revenue generated from
those ads. AdSense custom search ads can be displayed either alongside the
results from an AdSense Custom Search Engine or alongside internal search results
through the use of Custom Search Ads. Custom Search Ads are only available to
white-listed publishers. Although the revenue share from AdSense for Search
(51%) is lower than from AdSense for Content (68%) higher returns can be
achieved due to the potential for higher Click Through Rates.
AdSense for video:- AdSense for video allows publishers with video content to
generate revenue using ad placements from Google's extensive advertising network. The publisher is able to decide
what type of ads are shown against their video inventory. Formats available
include linear video ads (pre-roll or post-roll), overlay ads that display
AdSense text and display ads over the video content, and the TrueView format.
Publishers can also display companion ads - display ads that run alongside
video content outside the player. AdSense for video is for publishers running
video content within a player and not for YouTube
publishers.
Discontinued Types:
AdSense for
mobile content:-
AdSense for mobile content allowed 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. Instead of traditional JavaScript code, technologies such as
Java and Objective-C are used. As of February 2012, AdSense for Mobile Content
was rolled into the core AdSense for Content offering to better reflect the
lessening separation between desktop and mobile content.
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 or not in use. AdSense for
domains is currently being offered to all AdSense publishers, but it wasn't
always available to all. On December 12, 2008, Tech Crunch
reported that AdSense for Domains is available for all US publishers. On
February 22, 2012, Google announced that it was shutting down its Hosted
AdSense for Domains program.
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. 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. On December 3, 2012, Google discontinued
AdSense For Feeds program.
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 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.
- 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 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. 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" 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. 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.
