What is ADWORD

AdWords
is Google's flagship advertising product and main source of revenue. AdWords offers pay-per-click (PPC) advertising, and site-targeted advertising for both text and banner ads. The AdWords program includes local, national, and international distribution. Google's text advertisements are short, consisting of one title line and two content text lines. Image ads can be one of several different Interactive Advertising Bureau (IAB) standard sizes.

Pay-Per-Click advertisements (PPC)
Advertisers specify the words that should trigger their ads and the maximum amount they are willing to pay per click. When a user searches Google's search engine on www.google.com, ads for relevant words are shown as "sponsored links" on the right side of the screen, and sometimes above the main search results.
The ordering of the paid listings depends on other advertisers' bids (pay for placement P4P) and the "quality score" of all ads shown for a given search. The quality score is calculated by historical click-through rates and the relevance of an advertiser's ad text, keyword, and landing page to the search, as determined by Google. The quality score is also used by Google to set the minimum bids for an advertiser's keywords.[1]
The auction mechanism that determines the order of the ads has been called a "generalized second price" auction. It is a variation of the Vickrey auction.

Site targeted advertisements
In 2003 Google introduced site-targeted advertising. Using the AdWords control panel, advertisers can enter keywords of interest, and Google offers to place ads on what they claim are relevant sites within their content network. Advertisers then bid on a cost per mille (CPM) basis for placement. Advertisers can also enter domains directly. Google will provide a list of related sites that you can select along with your entered site.
Site targeting campaigns are mainly designed for branding purposes, as the ROI will almost always be considerably lower than a traditional content-targeted campaign. Your ad will take up the entire ad block (as opposed to being 1 of 4 ads in a traditional AdSense ad unit), which will make it more prominent but cost quite a bit more.
The minimum CPM you can set on a Site-Targeted campaign is 25 cents.

AdWords distribution
All AdWords ads are eligible to be shown on www.google.com. Advertisers also have the option of enabling their ads to show on Google's partner networks. The "search network" includes AOL search, Ask.com, and Netscape. Like www.google.com, these search engines show AdWords ads in response to user searches.
The "content network" shows AdWords ads on sites that are not search engines. These content network sites are those that use AdSense, the other side of the Google advertising model. AdSense is used by publishers who wish to bring traffic to their websites. Click through rates on the content network are typically much lower than those on the search network and are therefore ignored when calculating an advertiser's quality score.
Google automatically determines the subject of pages and displays relevant ads based on the advertisers' keyword lists. AdSense publishers may select channels to help direct Google's ad placements on their pages, to better track performance of their ad units. There are many different types of ads you can run across Google's network, including text ads, image ads (banner ads), local business ads, mobile text ads, and in-page video ads.
Google AdWords' main competitors are Yahoo! Search Marketing and Microsoft adCenter.

AdWords Account Management
To help clients with the complexity of building and managing AdWords accounts search engine marketing agencies and consultants offer account management as a business service. This has allowed organizations that otherwise would not have the advertising skills to reach a global, online audience. Google has started the Google Advertising Professionals program to certify agencies and consultants who have met specific qualifications and passed an exam.[2]. Google also provides account management software, called AdWords Editor.

Click-to-Call
Google Click-to-Call is a service provided by Google which allows users to call advertisers from Google search results pages. Users enter their phone number, Google calls them back and connects to the advertiser. Calling charges are paid by Google.

History
The AdWords product was launched in 2000.[3] At first advertisers would pay a monthly amount, and Google would set up and manage their campaign. To accommodate small businesses and those who wanted to manage their own campaigns, Google soon introduced the AdWords self-service portal. As of 2005, Google provides a campaign management service called Jumpstart [4] to assist advertisers in setting up their campaigns.
In 2005, Google launched the Google Advertising Profesional (GAP) Program to certify individuals and companies who have completed AdWords training and passed an exam. Due to the complexity of AdWords and the amount of money at stake, some advertisers hire a consultant to manage their campaigns.

Legal context
AdWords has generated lawsuits in the area of trademark law and click fraud. In 2006, Google settled a click fraud lawsuit for US$90 million. [5]
Overture Services, Inc. sued Google for patent infringement in April 2002 in relation to the AdWords service. Following Yahoo!'s acquisition of Overture, the suit was settled in 2004 with Google agreeing to issue 2.7 million shares of common stock to Yahoo! in exchange for a perpetual license under the patent. [6]

Technology
The AdWords system was initially implemented on top of the MySQL database engine. After the system had been launched, management decided to use a commercial database (Oracle) instead. As is typical of applications simultaneously written and tuned for one database, and ported to another, the system became much slower, so eventually it was returned to MySQL.

What is ADSENSE

AdSense is an ad serving program run by Google. Website owners can enroll in this program to enable text, image and, more recently, video advertisements on their sites. These ads are administered by Google and generate revenue on either a per-click or per-thousand-impressions basis. Google is also currently beta-testing a cost-per-action based service.
[edit] Overview
Google uses its search technology to serve ads based on website content, the user's geographical location, and other factors. Those wanting to advertise with Google's targeted ad system may sign up through AdWords. AdSense has become a popular method of placing advertising on a website because the ads are less intrusive than most banners, and the content of the ads is often relevant to the website.
Currently, the AdSense uses JavaScript code to incorporate the advertisements into a participating site. If it is included on a site which has not yet been crawled by the Mediabot, it will temporarily display advertisements for charitable causes known as public service announcements (PSAs). (The Mediabot is a separate crawler from the Googlebot that maintains Google's search index.)
Many sites use AdSense to monetize their content and some webmasters work hard to maximize 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 sites which attracts AdSense ads which pay out the most when they get clicked.
They use copy on their websites that encourage clicks on ads. Note that Google prohibits people from using phrases like "Click on my AdSense ads" to increase click rates. 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, in that it commands an advertiser to submit a sealed bid (not observable by competitors). Additionally, for any given click received, advertisers only pay one bid increment above the second-highest bid.

History
The underlying technlogy behind AdSense was derived originally from WordNet and Simpli, a company started by the founder of Wordnet — George A. Miller — and a number of professors and graduate students from Brown University, including James A. Anderson, Jeff Stibel and Steve Reiss.[1] A variation of this technology utilizing Wordnet was developed by Oingo, a small search engine company based in Santa Monica founded in 1998.[2] Oingo focused on semantic searches rather than brute force string searches.[3] Oingo changed its name to Applied Semantics, which was then bought by Google for $102 million in April 2003, to replace a similar system being developed in house.

[edit] AdSense for feeds
In May 2005, Google unveiled 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 the reader/browser, Google writes the ad content into the image that it returns. The ad 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 site in the same way as regular AdSense ads.
AdSense for search
A companion to the regular AdSense program, AdSense for search lets website owners place Google search boxes on their pages. When a user searches the web or the site with the search box, Google shares any ad revenue it makes from those searches with the site owner. However, only if the ads on the page are clicked, the publisher is paid. Adsense does not pay publishers for mere searches.

How AdSense works
Each time a visitor visits a page with an AdSense tag, a piece of JavaScript writes an iframe tag, whose "src" attribute includes the URL of the page.
For contextual advertisements, Google's servers use a cache of the page for the URL or the keywords in the URL itself to determine a set of high-value keywords. (Some of the details are described in the AdSense patent). If keywords have been cached already, ads are served for those keywords based on the AdWords bidding system.
For Site targeted ads, advertiser can choose the page or sites he wants to display ads on and pays on a CPM basis (cost per thousand impressions)
For referrals Google manage the subscriptions on a long term, to add money when the visitors either download the product of subscribe, that depend upon the sort of product.
For search, advertisements are added to the list of results and clicks on them make money.
To protect webmasters from bad use of their code, it is possible for them in the configuration panel to make a list of websites where advertisements are published. When other sites use their JavaScript code, clicks on ads are ignored.

What is BLOG

A blog (a portmanteau of web log) is a website where entries are written in chronological order and commonly displayed in reverse chronological order. "Blog" can also be used as a verb, meaning to maintain or add content to a blog.
History
Before blogging became popular, digital communities took many forms, including Usenet, commercial online services such as GEnie, BiX and the early CompuServe, e-mail lists[2] and Bulletin Board Systems (BBS). In the 1990s, Internet forum software, such as WebEx, created running conversations with "threads". Threads are topical connections between messages on a metaphorical "corkboard". Some have likened blogging to the Mass-Observation project of the mid-20th century.[citation needed]

1983–1990 (Pre-HTTP)
Usenet was the primary serial medium included in the original definition of the World Wide Web.[3] It featured the Moderated Newsgroup which allowed all posting in a newsgroup to be under the control of an individual or small group. Most such newsgroups were simply moderated discussion forums, however, in 1983-84, one exception, named mod.ber, was created, named after and managed by an individual: Brian E. Redman. Regularly, Redman and a few associates posted summaries of interesting postings and threads taking place elsewhere on the net. With its serial journal publishing style, presence on the pre-HTTP web and strong similarity to the common blog form which features links to interesting and cool places on the net chosen by the blogger, mod.ber had many of the characteristics commonly associated with the term "blog".[citation needed][original research?] It ceased operation after approximately 8 months. Brad Templeton calls the newsgroup rec.humor.funny (which he founded) the world's oldest still existing blog.
1994–2001
The modern blog evolved from the online diary, where people would keep a running account of their personal lives. Most such writers called themselves diarists, journalists, or journalers. A few called themselves "escribitionists". The Open Pages webring included members of the online-journal community. Justin Hall, who began eleven years of personal blogging in 1994 while a student at Swarthmore College, is generally recognized as one of the earliest bloggers,[5] as is Jerry Pournelle.[citation needed] Another early blog was Wearable Wireless Webcam, an online shared diary of a person's personal life combining text, video, and pictures transmitted live from a wearable computer and EyeTap device to a web site in 1994[6]. This practice of semi-automated blogging with live video together with text, was referred to as sousveillance, and such journals were also used as evidence in legal matters.
Other forms of journals kept online also existed. A notable example was game programmer John Carmack's widely read journal, published via the finger protocol. Some of the very earliest bloggers, like Steve Gibson of sCary's Quakeholio (now Shacknews) and Stephen Heaslip of Blue's News (still running since 1995 with online archives back to July 1996), evolved from the Quake scene and Carmack's .plan updates. Steve Gibson was hired to blog full-time by Ritual Entertainment on February 8th, 1997 [7], possibly making him the first hired blogger.
Websites, including both corporate sites and personal homepages, had and still often have "What's New" or "News" sections, often on the index page and sorted by date. One example of a news based "weblog" is the Drudge Report founded by the self-styled maverick reporter Matt Drudge, though apparently Drudge dislikes this classification. Another is the Institute for Public Accuracy which began posting news releases featuring several news-pegged one-paragraph quotes several times a week beginning in 1998. One noteworthy early precursor to a blog was the tongue-in-cheek personal website that was frequently updated by Usenet legend Kibo.
Early weblogs were simply manually updated components of common websites. However, the evolution of tools to facilitate the production and maintenance of web articles posted in reverse chronological order made the publishing process feasible to a much larger, less technical, population. Ultimately, this resulted in the distinct class of online publishing that produces blogs we recognize today. For instance, the use of some sort of browser-based software is now a typical aspect of "blogging". Blogs can be hosted by dedicated blog hosting services, or they can be run using blog software, such as WordPress, Movable Type, blogger or LiveJournal, or on regular web hosting services.
The term "weblog" was coined by Jorn Barger on 17 December 1997. The short form, "blog," was coined by Peter Merholz, who jokingly broke the word weblog into the phrase we blog in the sidebar of his blog Peterme.com in April or May of 1999.[8][9][10] This was quickly adopted as both a noun and verb ("to blog," meaning "to edit one's weblog or to post to one's weblog").
After a slow start, blogging rapidly gained in popularity. Blog usage spread during 1999 and the years following, being further popularized by the near-simultaneous arrival of the first hosted blog tools:
Open Diary launched in October 1998, soon growing to thousands of online diaries. Open Diary innovated the reader comment, becoming the first blog community where readers could add comments to other writers' blog entries.
Brad Fitzpatrick, a well known blogger started LiveJournal in March 1999.
Andrew Smales created Pitas.com in July 1999 as an easier alternative to maintaining a "news page" on a website, followed by Diaryland in September 1999, focusing more on a personal diary community.[11]
Evan Williams and Meg Hourihan (Pyra Labs) launched blogger.com in August 1999 (purchased by Google in February 2003)
Blogging combined the personal web page with tools to make linking to other pages easier — specifically permalinks, blogrolls and TrackBacks. This, together with weblog search engines enabled bloggers to track the threads that connected them to others with similar interests.
2001–2004
Several broadly popular American blogs emerged in 2001: Andrew Sullivan's AndrewSullivan.com, Ron Gunzburger's Politics1.com, Taegan Goddard's Political Wire, Glenn Reynolds' Instapundit, Charles Johnson's Little Green Footballs, and Jerome Armstrong's MyDD — all blogging primarily on politics (two earlier popular American political blogs were Bob Somerby's Daily Howler launched in 1998 and Mickey Kaus' Kausfiles launched in 1999).
By 2001, blogging was enough of a phenomenon that how-to manuals began to appear, primarily focusing on technique. The importance of the blogging community (and its relationship to larger society) increased rapidly. Established schools of journalism began researching blogging and noting the differences between journalism and blogging.
In 2002, Jerome Armstrong's friend and sometime business partner Markos Moulitsas Zúniga began DailyKos. With up to a million visits a day during peak events, it has now become one of the Internet's most popular blogs.
Also in 2002, many blogs focused on comments by U.S. Senate Majority Leader Trent Lott. Senator Lott, at a party honoring U.S. Senator Strom Thurmond, praised Senator Thurmond by suggesting that the United States would have been better off had Thurmond been elected president. Lott's critics saw these comments as a tacit approval of racial segregation, a policy advocated by Thurmond's 1948 presidential campaign. This view was reinforced by documents and recorded interviews dug up by bloggers. (See Josh Marshall's Talking Points Memo.) Though Lott's comments were made at a public event attended by the media, no major media organizations reported on his controversial comments until after blogs broke the story. Blogging helped to create a political crisis that forced Lott to step down as majority leader.
The impact of this story gave greater credibility to blogs as a medium of news dissemination. Though often seen as partisan gossips, bloggers sometimes lead the way in bringing key information to public light, with mainstream media having to follow their lead. More often, however, news blogs tend to react to material already published by the mainstream media.
Since 2002, blogs have gained increasing notice and coverage for their role in breaking, shaping, and spinning news stories. The Iraq war saw bloggers taking measured and passionate points of view that go beyond the traditional left-right divide of the political spectrum.
Blogging by established politicians and political candidates, to express opinions on war and other issues, cemented blogs' role as a news source. (See Howard Dean and Wesley Clark.) Meanwhile, an increasing number of experts blogged, making blogs a source of in-depth analysis. (See Daniel Drezner and J. Bradford DeLong.)
The second Iraq war was the first "blog war"[citation needed] in another way: Iraqi bloggers gained wide readership, and one, Salam Pax, published a book of his blog. Blogs were also created by soldiers serving in the Iraq war. Such "warblogs"[citation needed] gave readers new perspectives on the realities of war, as well as often offering different viewpoints from those of official news sources.
Blogging was used to draw attention to obscure news sources. For example, bloggers posted links to traffic cameras in Madrid as a huge anti-terrorism demonstration filled the streets in the wake of the March 11 attacks.
Bloggers began to provide nearly-instant commentary on televised events, creating a secondary meaning of the word "blogging": to simultaneously transcribe and editorialize speeches and events shown on television. (For example, "I am blogging Rice's testimony" means "I am posting my reactions to Condoleezza Rice's testimony into my blog as I watch her on television.") Real-time commentary is sometimes referred to as "liveblogging."

2004–present
In 2004, the role of blogs became increasingly mainstream, as political consultants, news services and candidates began using them as tools for outreach and opinion forming. Even politicians not actively campaigning, such as the UK's Labour Party's MP Tom Watson, began to blog to bond with constituents.
Minnesota Public Radio broadcast a program by Christopher Lydon and Matt Stoller called "The blogging of the President," which covered a transformation in politics that blogging seemed to presage. The Columbia Journalism Review began regular coverage of blogs and blogging. Anthologies of blog pieces reached print, and blogging personalities began appearing on radio and television. In the summer of 2004, both United States Democratic and Republican Parties' conventions credentialed bloggers, and blogs became a standard part of the publicity arsenal. Mainstream television programs, such as Chris Matthews' Hardball, formed their own blogs. Merriam-Webster's Dictionary declared "blog" as the word of the year in 2004.[12]
In 2004, Global Voices Online, a site which "aggregates, curates, and amplifies the global conversation online – shining light on places and people other media often ignore" surfaced, bringing to light bloggers from around the world. Today, the site has a relationship with Reuters and is responsible for breaking many global news stories.
Blogs were among the driving forces behind the "Rathergate" scandal, to wit: (television journalist) Dan Rather presented documents (on the CBS show 60 Minutes) that conflicted with accepted accounts of President Bush's military service record. Bloggers declared the documents to be forgeries and presented evidence and arguments in support of that view, and CBS apologized for what it said were inadequate reporting techniques (see Little Green Footballs). Many bloggers view this scandal as the advent of blogs' acceptance by the mass media, both as a news source and opinion and as means of applying political pressure.
Some bloggers have moved over to other media. The following bloggers (and others) have appeared on radio and television: Duncan Black (known widely by his pseudonym, Atrios), Glenn Reynolds (Instapundit), Markos Moulitsas Zúniga (Daily Kos), Alex Steffen (Worldchanging) and Ana Marie Cox (Wonkette). In counter-point, Hugh Hewitt exemplifies a mass media personality who has moved in the other direction, adding to his reach in "old media" by being an influential blogger.
Some blogs were an important news source during the December 2004 Tsunami such as Medecins Sans Frontieres, which used SMS text messaging to report from affected areas in Sri Lanka and Southern India. Similarly, during Hurricane Katrina in August 2005 and the aftermath a few blogs which were located in New Orleans, including the Interdictor and Gulfsails were able to maintain power and an Internet connection and disseminate information that was not covered by the Main Stream Media.
In the United Kingdom, The Guardian newspaper launched a redesign in September 2005, which included a daily digest of blogs on page 2. Also in June 2006, BBC News launched a weblog for its editors, following other news companies.[13]
In January 2005, Fortune magazine listed eight bloggers that business people "could not ignore": Peter Rojas, Xeni Jardin, Ben Trott, Mena Trott, Jonathan Schwartz, Jason Goldman, Robert Scoble, and Jason Calacanis.
In 2007, Tim O'Reilly proposed a Blogger's Code of Conduct.
