Google Adsense:
AdSense is an advertisement application run by Google. Website owners can enroll in this program to enable text, image, and more recently, video advertisements on their websites. These advertisements are administered by Google and generate revenue on either a per-click or per-impression basis. Google is also currently beta-testing a cost-per-action based service.

Things you Need:

1. A website or blog.
2. Google Adsense account.
3. Time.
   

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 AdWords. AdSense has become a popular method of placing advertising on a website because the advertisements are less intrusive than most banners, and the content of the advertisements is often relevant to the website.

Currently, AdSense uses JavaScript code to incorporate the advertisements into a participating website. If the advertisements are included on a website that has not yet been crawled by the Mediabot, AdSense will temporarily display advertisements for charitable causes, also known as public service announcements (PSAs). (The Mediabot is different from the Googlebot, which maintains Google's search index.)

Many websites use AdSense to monetize their content. AdSense has been particularly important for delivering advertising revenue to small websites that do not have the resources for developing advertising sales programs and salespeople. To fill a website with advertisements that are relevant to the topics discussed, webmasters implement a brief script 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 invest significant effort into maximizing their own AdSense income. They do this in three ways:[citation needed]

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.

Content-driven AdSensers sometimes bemoan Wikipedia. They seem to imagine that it ranks well for so many terms because it just has so many pages, and so many contributors, and is so well known. The wiki-mystique blinds people to the fact you can rank higher for terms by just doing some of the same things Wikipedia does.

• Have definition pages.
  If your site is about widget repair, and some of that involves widget lock washers, why don't you have a page devoted to explaining what "widget lock washers" are, where to buy them, and so on?
  Why does that matter?
  It gives Googlebot pages whose primary topic is easy to grasp. It produces SERP listings that do a good job of communicating to searchers exactly what they'll get if they click on your link. That, in turn, means folks who click are highly likely to find what they need, so Google will give that page more ranking love.
  It also gives you a nice landing page that can "sell" lots more content to the visitor. Once you know they arrived looking for something so specific, you should be able to tick off all the other pages that are relevant and link to them from there.
• Be coherent When people see wikipedia in the SERPs, they know what they're going to get if they click on it -- some encyclopedia-like explanation of plausible quality. Your website isn't as well known as Wikipedia, so you have to work hard to make sure your SERP entry gives a good clue as to what they're going to get. You don't want a SERP that claims to be all about "mastering pool shots" that actually links to a page describing drinking games for your swimming pool -- when Google sees all the folks who click on that are coming back to look elsewhere, your ranking goes in the crapper. This is where a well-thought-out domain name and carefully chosen URL text pays off. If my SERP's URL looks like www.widgetrepair.com/using-widget-lock-washers, and my SERP synopsis repeats the "how to use widget lock washers" message, and the linked-to page really is about that, then I'm clear about what I'm delivering and Google will reward that (assuming anybody is actually interested in that topic).

  If you see people are arriving at your "widget lock washers" page with a search term like "widget painting", figure out why that is. Too many not-on-target SE arrivals probably implies you need to split some content off and give it its own page (with lots of internal links to it, of course). Remember: people finding what they were looking for explains much of Wikipedia's ranking success.

  In case you missed it, I'll reiterate an important sub-point here. Your URL is the one thing on the Google SERP that you have 100% control over. Stop focusing on keyword stuffing your URLs and focus instead on using a URL that accurately conveys to the searcher what they'll get if they click on that link.

• Use intra-site links everywhere Lots of people waste enormous time and energy trying to get someone to link to them -- and don't lift a finger to link to themselves. Relevant intra-site links are gold! You don't have to beg anybody for them, you get to control the anchor text, and you don't have to add links back to anybody else to get them. Some people think it's a magic power that Wikipedia has to quickly pop to the top of any long-tail search. It's not. It's the fact that any new page invariably is linked to (with the key term in the anchor text) from one (usually more) other Wikipedia pages.
• Cover up your nav bars Do you feel like you already do use inline, intra-site links a lot? Baloney. Put your hand over the nav bars on your site. Now try to navigate. Can you get to all the pages on your site? How long before you hit a page that's a total dead end. The wiki structure essentially forces Wikipedia content to do things (like extensive intra-links with relevant anchor text) that are great for SEO. Ever get annoyed with how sometimes it seems like every other damn word on Wikipedia is a hotlink to another page? That shows how little you use intra-site, inline links in your own pages.
• Cover up your nav bar -- really! Somebody is saying "but my navigation is really logical and comprehensive, and I don't like the look of inline links." Ever hear of ad-blindness? Well people get just as blind to the navbar. I can put a big, red "CONTACT INFO" link in the navbar on every page -- and every day I will get an email saying "what's your address/phone# over there?" People cannot see your nav bar. Use inline links in the text with relevant anchor text. Santa knows if you're sleeping, but Google knows if a visitor didn't find what he wanted on your site -- and complaining that the visitor should have found the information won't alter Google's ranking one bit.
• Write, dammit, write! Sometimes the most obvious Wikipedia lesson is the most overlooked. I see people sometimes with a product to sell moaning over how they just can't get the SEO tricks right to bring in the free Google traffic. Then I go check out their site and they may literally have less than 10 pages of content. Which part of "Google likes content" did they not understand when they went to SEO school? Often people have extensive product manuals that they haven't even bothered to put online (or almost as bad, they put the whole manual up as a single PDF file), and yet they'll spend hours trying to tweak keyword density, or beg for links. Wikipedia shoves the message of "make some content someone wants to read" in your face, yet some people still don't get it.
• Edit as needed You can't be on WebmasterWorld long before you see people talking about being afraid of changing something on their website for fear it will drop their rankings. Sure, that's why Wikipedia never lets anyone change their pages... Change pages as needed, but most especially(!) to add in links to new relevant pages you've added, so those new pages will get immediate link love. If the last time you added a new page of content, you didn't have to go add inline links to it from at least a couple of other pages, then you haven't learned the Wikipedia Way.
• Make an Authority Page that Attracts Links OK, it is true that wikipedia also benefits from external links. You can compete on that front, too. People will often just link to them because it lets them avoid a lengthy explanation of a term. So supply those pedia-like pages that would be useful for someone who just wants to link to a term definition.

  In fact, if Wikipedia is overlapping into your Long Tail content, then why not jump on their back to higher rankings? Look at their page devoted to "widget wuffling". Make your own page devoted to defining that content. But make yours better/different. Supply something they don't. OK, now you've got a ready-made link campaign that will work a whole lot better than begging for cross-links. Use search tools to find all the pages hot-linking to Wikipedia's "widget wuffling" page. Track down those author email addresses and make your pitch. "I noticed your 'widget wuffling' link to Wikipedia and just wanted to point out that it says wuffling was first used in 1857. However, it was actually first used in 1856, as I've documented on my page at [...]".

  If you're staying awake, you've just realized that tracking down links to Wikipedia pages can be a real useful research tool for AdSensers in the content business.
  

Wikipedia dominates rankings for a lot of different reasons, but a lot of those reasons are things you can do as well or better than Wikipedia. And you're not handicapped by a lack of consistent style, a prohibition against commercial or controversial slants, or a horde of random visitors who keep patching your content when you're not looking! Don't hate Wikipedia -- learn from the free lessons they provide.

Google Inc has abandoned its efforts to sell advertising for broadcast radio stations, acknowledging that the three-year project has failed.

The leading Web search company said on Thursday that it plans to sell its Radio Automation business, which created software to automate broadcast radio programing, and phase out its Audio Ads service. The move will likely result in up to 40 people being laid off, Google said.

Google has been re-appraising initiatives intended to expand its income beyond Internet advertising, which accounts for more than 90 percent of total revenue.

In January, the company threw in the towel on a similar business to place advertisements in newspapers and other print media.

"We have always accepted that if you take risks not all of them will pay off," Google's vice president of product management, Susan Wojcicki, wrote on the company's blog on Thursday.

Advertisers will continue to be able to use Audio Ads until May 31, the company said.

Google -- which had 20,222 full-time employees as of December 31 -- would instead focus its efforts on placing ads on streaming audio over the Internet, according to Wojcicki.

JMP Securities analyst Sameet Sinha said that while diversifying is important for Google, the company should stick to efforts that are more closely related to its strength in the online market.

"The offline media business is going through significant turmoil anyway," he said. "To come in with a new business model, even if it makes things more efficient, is a difficult pitch at this point."

Sinha cited display advertising and ads on Web-connected mobile devices as areas where Google might have a better shot.

Google continues to invest in certain projects, despite the tough economy. Earlier this month, it unveiled Google Ocean, which charts Earth's bodies of water, and broadly expanded the breadth of its online map of the world.

Shares of Google rose 1.4 percent to $363.05.

Google said on Thursday it aimed to build a data center at an old paper mill in southeastern Finland that it bought from Stora Enso for 40 million euros ($51.7 million).

"We are currently considering to build a data center at this site," said Google spokesman Kay Oberbeck.

Google has dozens of data centers, or server farms, which consume significant amounts of energy, around the world.

In early 2008 Stora Enso closed down the loss-making Summa mill, which consumed 1,000 gigawatt hours of electricity per year, after nearly 53 years in operation.

The oldest parts of the mill were designed by renowned Finnish architect Alvar Aalto.

Stora Enso and Google have agreed that part of the mill site will be transferred to the city of Hamina for other industrial uses. The sale is expected to close by the end of the first quarter 2009.

Google Inc will allow developers to sell applications for its Android cell phone operating system beginning next week in the United States, as the search giant strives to expand in a smartphone arena dominated by Apple Inc.

Google's announcement marked an important step in the search giant's quest to catch up with Apple in the fast-growing market for smartphones.

It signals Google's commitment to expand into a relatively hot mobile market, even as it pulls back on certain other initiatives such as broadcast radio.

Google said in a blog post on Friday its Android Market will initially carry paid applications from developers in the United States and Britain, with plans to allow developers in Germany, Austria, the Netherlands, France and Spain to participate later this quarter.

That could present an outlet for developers such as Electronic Arts Inc that have been anxious to expand sales of their mobile phone games to the Android Market, which has been limited to free applications until now.

Smartphones, which allow consumers to browse the Web, send email, play games and listen to music, in addition to making calls, are one of the few bright spots in a slowing technology and consumer electronics market.

While overall unit sales of cell phones declined 12.6 percent year-over-year in the fourth quarter, smartphone shipments increased 22.5 percent, according to research firm Gartner.

The T-Mobile G1 phone uses the Android operating system.

The availability of applications that run on a particular smartphone are important to define and distinguish the product, said analyst Rob Enderle of the Enderle Group.

"It's what's providing that extra value and getting people into the stores," he said.

Apple, for instance, enticed a large community of developers to create both paid and free applications for its iPhone.

According to a Google spokeswoman, there are currently 1,000 applications that run on Android smartphones.

Consumers will buy the forthcoming paid Android applications via the Google Checkout payment product.

Shares of Google were down less than 1 percent at $360 in late afternoon trading.
