IPv4 means Internet Protocol version 4, whereas IPv6 means Internet Protocol version 6.

IPv4 is 32 bits IP address that we use commonly, it can be 192.168.8.1, 10.3.4.5 or other 32 bits IP addresses. IPv4 can support up to 232 addresses, however the 32 bits IPv4 addresses are finishing to be used in near future, so IPv6 is developed as a replacement.

IPv6 is 128 bits, can support up to 2128 addresses to fulfill future needs with better security and network related features. Here are some examples of IPv6 address:

1050:0:0:0:5:600:300c:326b
ff06::c3
0:0:0:0:0:0:192.1.56.10

The below diagram shows the two different types of Cat 5 network cable, 'straight-thru' and 'crossover'
Straight-thru cables are used between a Hub and a computer, and crossover cables are used directly between two PC's, when no Hub is being used.

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.

The use of proxy is allowed but if you use a proxy to enter your adsense account your account will be disabled. It has been seen lately that you can use proxies for logins, but sign up must be from a real computer. Proxies like hidemyass, armyproxy, schoolproxy, etc., can be used after signup.

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 sales people. 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.

History:

Oingo, Inc., a privately held company located in Los Angeles, was started in 1998 by Gilad Elbaz and Adam Weissman. Oingo developed a proprietary search algorithm that was based on word meanings and built upon an underlying lexicon called WordNet, which was developed over the previous 15 years by researchers at Princeton University, led by George Miller.[2]

Oingo changed its name to Applied Semantics in 2001,[3] which was later acquired by Google in April 2003 for US$102 million.[4]

In 2009, Google AdSense announced that it would now be offering new features, including the ability to "enable multiple networks to display ads".


Types:

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.
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.

Description:

Although contextual advertising in general refers to the inclusion of advertisements adjacent to relevant online context (e.g., Google AdSense), in-text advertising places hyperlinks directly into the text of the webpage. Most in-text advertising has the following characteristics:

1. The text associated with an advertisement is identified by a double-underline to differentiate it from regular hyperlinks.
2. An in-page bubble containing advertising content appears when the cursor is positioned over the corresponding text.
3. When the mouse is moved away from the double-underline hyperlink, the bubble disappears.
4. If the reader is interested in learning more about the product being offered, he can simply click on the ad bubble to go to the advertiser's site.
5. Some examples of in-text ad providers include Vibrant, Infolinks, and Kontera

Advertising Model:

In text advertising works on a cost per click (CPC) model, which means that each time a website visitor clicks on an In-Text ad, the websites owner gets paid by the advertiser.

Advantages:

In-text advertising can supplement other methods of contextual advertising since it monetizes the website content itself without taking any extra space of the web-page. The integration process of in-text ads usually requires the insertion of script code into the web-pages' html. After that, the entire process is intelligently automated. The advantages of this type of advertising have been discussed on the Online Marketing professional blog - Online Siesta

Criticism:

The use of this type of advertising in news and journalism websites has been criticized by journalism ethics counselors as "ethically problematic at the least and potentially quite corrosive of journalistic quality and credibility."[2] However, publishers such as the Indianapolis Star who use in-text advertising have reported that despite early objections by some readers, such complaints have "tapered off".

SEO is an acronym for "search engine optimization" or "search engine optimizer." Deciding to hire an SEO is a big decision that can potentially improve your site and save time, but you can also risk damage to your site and reputation. Make sure to research the potential advantages as well as the damage that an irresponsible SEO can do to your site. Many SEOs and other agencies and consultants provide useful services for website owners, including:

* Review of your site content or structure
* Technical advice on website development: for example, hosting, redirects, error pages, use of JavaScript
* Content development
* Management of online business development campaigns
* Keyword research
* SEO training
* Expertise in specific markets and geographies.

Keep in mind that the Google search results page includes organic search results and often paid advertisement (denoted by the heading "Sponsored Links") as well. Advertising with Google won't have any effect on your site's presence in our search results. Google never accepts money to include or rank sites in our search results, and it costs nothing to appear in our organic search results. Free resources such as Webmaster Tools, the official Webmaster Central blog, and our discussion forum can provide you with a great deal of information about how to optimize your site for organic search. Many of these free sources, as well as information on paid search, can be found on Google Webmaster Central.

Before beginning your search for an SEO, it's a great idea to become an educated consumer and get familiar with how search engines work. We recommend starting here:

* Google Webmaster Guidelines
* Google 101: How Google crawls, indexes and serves the web.

If you're thinking about hiring an SEO, the earlier the better. A great time to hire is when you're considering a site redesign, or planning to launch a new site. That way, you and your SEO can ensure that your site is designed to be search engine-friendly from the bottom up. However, a good SEO can also help improve an existing site.

Some useful questions to ask an SEO include:

* Can you show me examples of your previous work and share some success stories?
* Do you follow the Google Webmaster Guidelines?
* Do you offer any online marketing services or advice to complement your organic search business?
* What kind of results do you expect to see, and in what timeframe? How do you measure your success?
* What's your experience in my industry?
* What's your experience in my country/city?
* What's your experience developing international sites?
* What are your most important SEO techniques?
* How long have you been in business?
* How can I expect to communicate with you? Will you share with me all the changes you make to my site, and provide detailed information about your recommendations and the reasoning behind them?

While SEOs can provide clients with valuable services, some unethical SEOs have given the industry a black eye through their overly aggressive marketing efforts and their attempts to manipulate search engine results in unfair ways. Practices that violate our guidelines may result in a negative adjustment of your site's presence in Google, or even the removal of your site from our index. Here are some things to consider:

* Be wary of SEO firms and web consultants or agencies that send you email out of the blue.

Amazingly, we get these spam emails too:

"Dear google.com,
I visited your website and noticed that you are not listed in most of the major search engines and directories..."

Reserve the same skepticism for unsolicited email about search engines as you do for "burn fat at night" diet pills or requests to help transfer funds from deposed dictators.
* No one can guarantee a #1 ranking on Google.

Beware of SEOs that claim to guarantee rankings, allege a "special relationship" with Google, or advertise a "priority submit" to Google. There is no priority submit for Google. In fact, the only way to submit a site to Google directly is through our Add URL page or by submitting a Sitemap and you can do this yourself at no cost whatsoever.
* Be careful if a company is secretive or won't clearly explain what they intend to do.

Ask for explanations if something is unclear. If an SEO creates deceptive or misleading content on your behalf, such as doorway pages or "throwaway" domains, your site could be removed entirely from Google's index. Ultimately, you are responsible for the actions of any companies you hire, so it's best to be sure you know exactly how they intend to "help" you. If an SEO has FTP access to your server, they should be willing to explain all the changes they are making to your site.
* You should never have to link to an SEO.

Avoid SEOs that talk about the power of "free-for-all" links, link popularity schemes, or submitting your site to thousands of search engines. These are typically useless exercises that don't affect your ranking in the results of the major search engines -- at least, not in a way you would likely consider to be positive.
* Choose wisely.

While you consider whether to go with an SEO, you may want to do some research on the industry. Google is one way to do that, of course. You might also seek out a few of the cautionary tales that have appeared in the press, including this article on one particularly aggressive SEO: http://seattletimes.nwsource.com/html/businesstechnology/2002002970_nwbizbriefs12.html. While Google doesn't comment on specific companies, we've encountered firms calling themselves SEOs who follow practices that are clearly beyond the pale of accepted business behavior. Be careful.
* Be sure to understand where the money goes.

While Google never sells better ranking in our search results, several other search engines combine pay-per-click or pay-for-inclusion results with their regular web search results. Some SEOs will promise to rank you highly in search engines, but place you in the advertising section rather than in the search results. A few SEOs will even change their bid prices in real time to create the illusion that they "control" other search engines and can place themselves in the slot of their choice. This scam doesn't work with Google because our advertising is clearly labeled and separated from our search results, but be sure to ask any SEO you're considering which fees go toward permanent inclusion and which apply toward temporary advertising.
* What are the most common abuses a website owner is likely to encounter?

One common scam is the creation of "shadow" domains that funnel users to a site by using deceptive redirects. These shadow domains often will be owned by the SEO who claims to be working on a client's behalf. However, if the relationship sours, the SEO may point the domain to a different site, or even to a competitor's domain. If that happens, the client has paid to develop a competing site owned entirely by the SEO.

Another illicit practice is to place "doorway" pages loaded with keywords on the client's site somewhere. The SEO promises this will make the page more relevant for more queries. This is inherently false since individual pages are rarely relevant for a wide range of keywords. More insidious, however, is that these doorway pages often contain hidden links to the SEO's other clients as well. Such doorway pages drain away the link popularity of a site and route it to the SEO and its other clients, which may include sites with unsavory or illegal content.
* What are some other things to look out for?

There are a few warning signs that you may be dealing with a rogue SEO. It's far from a comprehensive list, so if you have any doubts, you should trust your instincts. By all means, feel free to walk away if the SEO:
o owns shadow domains
o puts links to their other clients on doorway pages
o offers to sell keywords in the address bar
o doesn't distinguish between actual search results and ads that appear on search results pages
o guarantees ranking, but only on obscure, long keyword phrases you would get anyway
o operates with multiple aliases or falsified WHOIS info
o gets traffic from "fake" search engines, spyware, or scumware
o has had domains removed from Google's index or is not itself listed in Google

If you feel that you were deceived by an SEO in some way, you may want to report it.
