IP Address

2007-11-04T07:35:00.000-08:00

An IP address (Internet Protocol address) is a unique address that certain electronic devices use in order to identify and communicate with each other on a computer network utilizing the Internet Protocol standard (IP)—in simpler terms, a computer address. Any participating network device—including routers, switches, computers, infrastructure servers (e.g., NTP, DNS, DHCP, SNMP, etc.), printers, Internet fax machines, and some telephones—can have their own address that is unique within the scope of the specific network. Some IP addresses are intended to be unique within the scope of the global Internet, while others need to be unique only within the scope of an enterprise.

In other words, the IP address acts as a locator for one IP device to find another and interact with it. It is not intended, however, to act as an identifier that always uniquely identifies a particular device.

An IP address can also be thought of as the equivalent of a street address or a phone number (compare: VoIP (voice over (the) internet protocol)) for a computer or other network device on the Internet. Just as each street address and phone number uniquely identifies a building or telephone, an IP address can uniquely identify a specific computer or other network device on a network. An IP address differs from other contact information, however, because the linkage of a user's IP address to his/her name is not publicly available information.

Further, an IP address is not necessarily linked, in a persistent way, to a physical location or even data link layer address. In the past, an IP address could be considered a unique identifier of a particular IP host, in addition to being a locator. When it was usable as an identifier, it was static, and it was assumed to be globally unique from end to end of the Internet.

In current practice, an IP address is less likely to be an identifier, due to technologies such as:

Dynamic assignment, as with an address that is assigned by the access device by which the user's host connects over a dialup telephone line or by a set-top box for an IP over cable network. However the network provider maintains a database of which IP address was assigned to which access port on dialup, or MAC address on LANs or broadband networks. This information, assuming it is available to the investigator, may help to identify the computer, although that is unlikely if it was a dialup connection where the identifier is of the dial-in port, not the computer itself. More extensive forensic work, with access to telephone records, may identify the calling telephone, although that may itself be a "cutout" on the way to the real telephone.

Network address translation (or NAT), a feature common on gateway routers in corporate networks or home LANs, where the address visible to the Internet is the "outside" of a device that maps it to a completely different and hidden address on the "inside". See IP Address Translation, below.

Nofollow Tag

2007-10-28T10:50:00.000-07:00

Nofollow is a non-standard HTML attribute value used to instruct search engines that a hyperlink should not influence the link target's ranking in the search engine's index. It is intended to reduce the effectiveness of certain types of spamdexing, thereby improving the quality of search engine results and preventing spamdexing from occurring in the first place.

While all engines that support the attribute exclude links that use the attribute from their ranking calculation, the details about the exact interpretation of the attribute vary from search engine to search engine.

* Google takes "nofollow" literally and does not "follow" the link at all. That is supposedly their official statement, but experiments conducted by SEOs show conflicting results. They show instead that Google does follow the link, but not index the linked-to page, unless it was in Google's index already for other reasons (such as other, non-nofollow links that point to the page). Links with NOFOLLOW are included in the back-links reporting data at Google's Webmaster Central.
* Yahoo! "follows it", but excludes it from their ranking calculation.
* MSN Search respects "nofollow" as regards not counting the link in their ranking, but it is not proven whether or not MSN follows the link.
* Ask.com does not use the attribute for anything.

Google Bombing

2007-10-13T09:42:00.000-07:00

A Google bomb (also referred to as a 'link bomb') is Internet slang for a certain kind of attempt to influence the ranking of a given page in results returned by the Google search engine, often with humorous or political intentions।[1] Because of the way that Google's algorithm works, a page will be ranked higher if the sites that link to that page use consistent anchor text. A Google bomb is created if a large number of sites link to the page in this manner. Google bomb is used both as a verb and a noun. The phrase "Google bombing" was introduced to the New Oxford American Dictionary in May 2005.[2] Google bombing is closely related to spamdexing, the practice of deliberately modifying HTML pages to increase the chance of their being placed close to the beginning of search engine results, or to influence the category to which the page is assigned in a misleading or dishonest manner.

The term Googlewashing was coined in 2003 to describe the use of media manipulation to change the perception of a term, or push out competition from search engine results pages (SERPs)

Some website operators have adapted Google bombing techniques to do spamdexing। This includes, among other techniques, posting of links to a site in an Internet forum along with phrases the promoter hopes to associate with the site (see Spam in blogs)। Unlike conventional message board spam, the object is not to attract readers to the site directly, but to increase the site's ranking under those search terms। Promoters using this technique frequently target forums with low reader traffic, in hopes that it will fly under the moderators' radar. Wikis in particular are often the target of this kind of page rank vandalism, as all of the pages are freely editable.

Another technique is for the owner of an Internet domain name to set up the domain's DNS entry so that all subdomains are directed to the same server। The operator then sets up the server so that page requests generate a page full of desired Google search terms, each linking to a subdomain of the same site, with the same title as the subdomain in the requested URL. Frequently the subdomain matches the linked phrase, with spaces replaced by underscores or hyphens. Since Google treats subdomains as distinct sites, the effect of a large number of subdomains linking to each other is a boost to the PageRank of those subdomains and of any other site they link to.

On 2 February 2007, many have noticed changes in the Google algorithm that largely affects, among other things, Google bombs: only roughly 10% of the Google bombs worked as of 15 February 2007। This is largely due to Google refactoring its valuation of PageRank.

White hat V/S black hat

2007-09-23T13:13:00.000-07:00

SEO techniques are classified by some into two broad categories: techniques that search engines recommend as part of good design, and those techniques that search engines do not approve of and attempt to minimize the effect of, referred to as spamdexing. Some industry commentators classify these methods, and the practitioners who employ them, as either white hat SEO, or black hat SEO. White hats tend to produce results that last a long time, whereas black hats anticipate that their sites will eventually be banned once the search engines discover what they are doing.

A SEO tactic, technique or method is considered white hat if it conforms to the search engines' guidelines and involves no deception. As the search engine guidelines are not written as a series of rules or commandments, this is an important distinction to note. White hat SEO is not just about following guidelines, but is about ensuring that the content a search engine indexes and subsequently ranks is the same content a user will see.

White hat advice is generally summed up as creating content for users, not for search engines, and then making that content easily accessible to the spiders, rather than attempting to game the algorithm. White hat SEO is in many ways similar to web development that promotes accessibility, although the two are not identical.

Black hat SEO attempts to improve rankings in ways that are disapproved of by the search engines, or involve deception. One black hat technique uses text that is hidden, either as text colored similar to the background, in an invisible div, or positioned off screen. Another method gives a different page depending on whether the page is being requested by a human visitor or a search engine, a technique known as cloaking.

Search engines may penalize sites they discover using black hat methods, either by reducing their rankings or eliminating their listings from their databases altogether. Such penalties can be applied either automatically by the search engines' algorithms, or by a manual site review.

One infamous example was the February 2006 Google removal of both BMW Germany and Ricoh Germany for use of deceptive practices Both companies, however, quickly apologized, fixed the offending pages, and were restored to Google's list.

Keyword Stuffing

2007-09-19T06:00:00.000-07:00

Keyword stuffing is considered to be an unethical search engine optimization (SEO) technique. Keyword stuffing occurs when a web page is loaded with keywords in the meta tags or in content. The repetition of words in meta tags may explain why many search engines no longer use these tags.

Keyword stuffing is used to obtain maximum search engine ranking and visibility for particular phrases. A word that is repeated too often may raise a red flag to search engines. In particular, Google has been known to delist sites employing this technique, and their indexing algorithm specifically lowers the ranking of sites that do this.

Hiding text out of view of the visitor is done in many different ways. Text colored to blend with the background, CSS "Z" positioning to place text "behind" an image – and therefore out of view of the visitor – and CSS absolute positioning to have the text positioned far from the page center, are all common techniques. As of 2005, some of these invisible text techniques can be detected by major search engines.

"Noscript" tags are another way to place hidden content within a page. While they are a valid optimization method for displaying an alternative representation of scripted content, they may be abused, since search engines may index content that is invisible to most visitors.

Inserted text sometimes includes words that are frequently searched (such as "sex"), even if those terms bear little connection to the content of a page, in order to attract traffic to advert-driven pages.

Keyword stuffing can be considered to be either a white hat or a black hat tactic, depending on the context of the technique, and the opinion of the person judging it। While a great deal of keyword stuffing is employed to aid in spamdexing, which is of little benefit to the user, keyword stuffing in certain circumstances is designed to benefit the user and not skew results in a deceptive manner। Whether the term carries a pejorative or neutral connotation is dependent on whether the practice is used to pollute the results with pages of little relevance, or to direct traffic to a page of relevance that would have otherwise been de-emphasized due to the search engine's inability to interpret and understand related ideas.

Search Engine Optimization

2007-09-03T05:14:00.000-07:00

Search engine optimization (SEO) is the process of improving the volume and quality of traffic to a web site from search engines via "natural" ("organic" or "algorithmic") search results. Usually, the earlier a site is presented in the search results, or the higher it "ranks", the more searchers will visit that site. SEO can also target different kinds of search, including image search, local search, and industry-specific vertical search engines.

As a marketing strategy for increasing a site's relevance, SEO considers how search algorithms work and what people search for. SEO efforts may involve a site's coding, presentation, and structure, as well as fixing problems that could prevent search engine indexing programs from fully spidering a site. Other, more noticeable efforts may include adding unique content to a site, ensuring that content is easily indexed by search engine robots, and making the site more appealing to users. Another class of techniques, known as "Black Hat" SEO or spamdexing, use methods such as link farms and keyword stuffing that tend to harm search engine user experience. Search engines look for sites that employ these techniques and may remove their listings.

The initialism "SEO" can also refer to "search engine optimizers", a term adopted by an industry of consultants who carry out optimization projects on behalf of clients, and by employees who perform SEO services in-house। Search engine optimizers may offer SEO as a stand-alone service or as a part of a broader marketing campaign. Because effective SEO may require changes to the HTML source code of a site, SEO tactics may be incorporated into web site development and design. The term "search engine friendly" may be used to describe web site designs, menus, content management systems and shopping carts that are easy to optimize.

Spamdexing

2007-08-23T04:39:00.000-07:00

Spamdexing is any of various methods to manipulate the relevancy or prominence of resources indexed by a search engine, usually in a manner inconsistent with the purpose of the indexing system. It is a form of search engine optimization. Search engines use a variety of algorithms to determine relevancy ranking. Some of these include determining whether the search term appears in the META keywords tag, others whether the search term appears in the body text or URL of a web page. Many search engines check for instances of spamdexing and will remove suspect pages from their indexes.

The rise of spamdexing in the mid-1990s made the leading search engines of the time less useful, and the success of Google at both producing better search results and combating keyword spamming, through its reputation-based PageRank link analysis system, helped it become the dominant search site late in the decade, where it remains. Although it has not been rendered useless by spamdexing, Google has not been immune to more sophisticated methods either. Google bombing is another form of search engine result manipulation, which involves placing hyperlinks that directly affect the rank of other sites[1]. Google first algorithmically combated Google bombing on January 25, 2007.[citation needed]

The earliest known reference to the term spamdexing is by Eric Convey in his article "Porn sneaks way back on Web," The Boston Herald, May 22, 1996, where he said:

The problem arises when site operators load their Web pages with hundreds of extraneous terms so search engines will list them among legitimate addresses. The process is called "spamdexing," a combination of spamming — the Internet term for sending users unsolicited information — and "indexing."[2]

Common spamdexing techniques can be classified into two broad classes: content spam and link spam.
